[0001] This application relates to the field of interior design technology, and in particular to an interactive method, device and electronic device for curved windows. Background Technology

[0002] Existing architectural design and interior design software typically offers drawing and editing functions for straight walls and rectangular windows. However, these software programs often have the following shortcomings when dealing with curved structures:

[0003] 1. Lack of flexible creation and editing support for curved windows and curved walls; 2. Difficulty in establishing the connection between curved windows and curved walls; 3. Movement and shape adjustment of curved windows are usually not intuitive and precise enough; 4. Difficulty in ensuring the connection between curved windows and curved walls during the editing process; 5. Lack of intelligent handling mechanism for special cases (such as large curved walls).

[0004] The aforementioned shortcomings severely impact the creativity and efficiency of architects when dealing with complex curved structures, and also affect the final design outcome. Therefore, the interactive design of curved windows has become a problem to be solved in housing design. Summary of the Invention

[0005] In view of the above problems, embodiments of this application provide a curved window interaction method, apparatus, and electronic device that overcomes or at least partially solves the above problems.

[0006] In a first aspect, embodiments of this application provide a curved window interaction method, including:

[0007] In response to the drag input of the target curved window, a target curved wall that meets the adsorption conditions between the target curved window and the target curved window is identified, and the target curved window is adsorbed to the target curved wall;

[0008] Upon receiving a motion interaction input for the target curved window, in response to the motion interaction input, the target curved window is controlled to move on the target curved wall to update the position of the target curved window;

[0009] Upon receiving an update input for the first endpoint of the target curved window, in response to the update input, the position of the first endpoint on the target curved wall is adjusted to update the shape of the target curved window.

[0010] Secondly, embodiments of this application provide an arc-shaped window interaction device, comprising:

[0011] The identification and adsorption module is used to identify a target curved wall that meets the adsorption conditions between the target curved window and the target curved window in response to the drag input of the target curved window, and adsorb the target curved window to the target curved wall.

[0012] The control module is configured to, upon receiving a motion interaction input to the target curved window, control the target curved window to move on the target curved wall in response to the motion interaction input, so as to update the position of the target curved window;

[0013] An adjustment module is configured to, upon receiving an update input for the first endpoint of the target curved window, adjust the position of the first endpoint on the target curved wall in response to the update input, so as to update the shape of the target curved window.

[0014] Thirdly, embodiments of this application provide an electronic device, including a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the steps of the arc-shaped window interaction method as described in the first aspect above.

[0016] The technical solution of this application embodiment, in response to the drag input of the target curved window, identifies the target curved wall that meets the adsorption conditions between the target curved window and the target curved window, and adsorbs the target curved window to the target curved wall. This allows the shape of the window to adapt to the wall, achieving a reasonable match between the target curved window and the target curved wall, and greatly improving design efficiency. Based on the interactive input of moving the target curved window, the target curved window is controlled to move on the target curved wall, and the shape of the target curved window is updated based on the update input of the first endpoint of the target curved window. This ensures that the target curved window always fits on the target curved wall during movement and deformation, improving design accuracy. Moreover, the intuitive interaction method makes the design of complex curved structures simple and easy to use.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of this application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Multiple embodiments in this application may include two or more.

[0035] In the various embodiments of this application, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0036] This application provides an embodiment of an interactive method for an arc-shaped window, such as... Figure 1 As shown, it includes:

[0037] Step 101: In response to the drag input of the target curved window, identify the target curved wall that meets the adsorption conditions between the target curved window and the target curved window, and adsorb the target curved window to the target curved wall.

[0038] The arc-shaped window provided in this application embodiment includes the following parameters: arc center point (representing the specific location of the arc-shaped window, specifically the center point of the middle arc), start point (start, representing the initial position of the arc-shaped window), end point (end, representing the final position of the arc-shaped window), chord length (chord, representing the straight-line distance from start to end), radius (radius, representing the radius of the circle containing the arc-shaped window, which is also the radius of the arc-shaped window), arc-shaped window category (whether it is a large arc or a small arc), and clockwise / counterclockwise direction of the arc-shaped window (determined based on the arc direction from the start point to the end point). Specifically, the arc-shaped window is determined to be a large or small arc by comparing the distance from the arc center point to the chord length and the arc-shaped window radius. If the distance from the arc center point to the chord length is greater than the arc-shaped window radius, it indicates a large arc; if the distance from the arc center point to the chord length is less than or equal to the arc-shaped window radius, it indicates a small arc. Typically, isSmall can be used to distinguish between large and small arcs; isSmall = true indicates a small arc, and isSmall = false indicates a large arc. Counterclockwise is used to indicate the clockwise or counterclockwise direction of a curved window. Specifically: Counterclockwise = true indicates counterclockwise, and Counterclockwise = false indicates clockwise. Figure 2 In the arc-shaped window shown, the distance from the center point of the arc to the chord length is less than the radius of the arc-shaped window. The arc-shaped window is a small arc, and the direction of the arc from the starting point to the ending point is clockwise, indicating that the arc-shaped window is in a clockwise direction.

[0039] After clicking the "Create Curved Window" button, a target curved window is drawn on the canvas. The mouse position represents the center point of the arc, which also indicates the position of the target curved window. The target curved window updates its position information as the mouse moves across the canvas. If a target curved wall close to the target curved window is detected, it is snapped to the wall. That is, when a target curved wall is detected on the canvas whose distance from the target curved window meets the snapping condition, the target curved window is snapped to the target curved wall. Snapping the target curved window to the target curved wall allows the window's shape to adapt to the wall, achieving a reasonable match between the curved window and the curved wall, significantly improving design efficiency.

[0040] Step 102: Upon receiving a motion interaction input for the target curved window, in response to the motion interaction input, control the target curved window to move on the target curved wall to update the position of the target curved window.

[0041] After the target curved window is snapped to the target curved wall, it can receive interactive input for movement. For example, after selecting the target curved window, it can be dragged to move it, with the drag point being the center point of the arc. To ensure the target curved window remains on the target curved wall, a large-distance snapping threshold can be applied to the drag point. This means that even if the mouse is not on the target curved window (e.g., at a certain distance), the target curved window will still remain snapped to the target curved wall, allowing dragging of the target curved window based on mouse movements.

[0042] Responding to mobile interactive input, the target curved window is controlled to move on the target curved wall. While maintaining the shape of the target curved window, its position on the target curved wall is adjusted, and the position of the target curved window is updated. This ensures that the target curved window always fits on the target curved wall during the movement, thus improving design accuracy.

[0043] Step 103: Upon receiving an update input for the first endpoint of the target curved window, adjust the position of the first endpoint on the target curved wall in response to the update input to update the shape of the target curved window.

[0044] After snapping the target curved window to the target curved wall, it can receive update input for the first endpoint of the target curved window, which is either the start or end point of the target curved window. This update input for the first endpoint can be understood as dragging the first endpoint. During the dragging of the first endpoint, the target curved window remains on the target curved wall. Therefore, we also need to snap the mouse position to the wall at a large distance during dragging. This way, even if the mouse position is not on the target curved window, the target curved window will remain snapped to the target curved wall, allowing dragging of the target curved window's endpoint based on mouse movements.

[0045] In response to the update input of the first endpoint of the target curved window, the position of the first endpoint on the target curved wall is adjusted. Since the position of the first endpoint changes while the second endpoint remains unchanged on the target curved wall, the target curved window deforms. This deformation is based on the update input of the endpoints. For example, by changing the position of the first endpoint of the target curved window, the target curved window can be changed from a small arc to a large arc, or vice versa. During the deformation process, the target curved window remains attached to the target curved wall. By adjusting the position of the first endpoint of the target curved window on the target curved wall and updating the shape of the target curved window attached to the target curved wall, the shape of the target curved window is updated, ensuring that the target curved window remains attached to the target curved wall during deformation, thus improving design accuracy.

[0046] The above-described implementation scheme of this application, in response to the drag input of the target curved window, identifies the target curved wall that meets the adsorption conditions between the target curved window and the target curved wall, and adsorbs the target curved window to the target curved wall. This allows the shape of the window to adapt to the wall, achieving a reasonable match between the target curved window and the target curved wall, and greatly improving design efficiency. Based on the interactive input of moving the target curved window, the movement of the target curved window on the target curved wall is controlled, and the shape of the target curved window is updated based on the update input of the first endpoint of the target curved window. This ensures that the target curved window always fits against the target curved wall during movement and deformation, improving design accuracy. Moreover, the intuitive interaction method makes the design of complex curved structures simple and easy to use.

[0047] Furthermore, the highly flexible, precise, and easy-to-use arc-shaped structure design provided by the embodiments of this application offers new possibilities for architectural and interior design scenarios.

[0048] The process of adsorbing a target curved window onto a target curved wall is described below. In response to drag input to the target curved window, identifying the target curved wall that meets the adsorption conditions between the target curved window and the target curved wall, and adsorbing the target curved window onto the target curved wall, the process includes:

[0049] In response to drag input, update the position information of the target curved window;

[0050] During the process of dragging the target arc-shaped window to update its position information, identify whether there is an arc-shaped wall whose distance from the target arc-shaped window meets the adsorption conditions;

[0051] If a target arc wall is identified where the absolute value of the difference between the distance between the center of the circle and the arc center point of the target arc window and the wall radius is less than the adsorption threshold, the position of the arc center point of the target arc window on the corresponding arc center point on the target arc wall is determined, and the circle information of the target arc window is updated.

[0052] Based on the position of the arc center point, the chord length corresponding to the target arc window, the circle information corresponding to the target arc window, and the arc category to which the target arc window belongs, calculate the starting and ending positions of the target arc window on the target arc wall.

[0053] Draw the target curved window on the target curved wall based on the starting and ending positions.

[0054] Based on the drag input of the target curved window on the canvas, the position information of the target curved window on the canvas is updated, and the shape of the target curved window remains unchanged during this process. While updating the position information of the target curved window on the canvas, it is identified whether there are curved walls whose distance from the target curved window meets the adsorption condition. Curved walls whose absolute value of the difference between the distance between the center of the identified circle and the center point of the arc of the target curved window and the radius of the wall is less than the adsorption threshold are identified as target curved walls.

[0055] like Figure 3A As shown, the difference between the distance d between the center of the curved wall and the center point of the target curved window, and the wall radius R, is positive. When the difference is less than the adsorption threshold, the curved wall is determined to be the target curved wall that has an adsorption relationship with the target curved window. Figure 3B As shown, the difference between the distance d between the center of the curved wall and the center point of the target curved window and the wall radius R is negative. If the absolute value of the difference is less than the adsorption threshold, the curved wall is determined to be the target curved wall that has an adsorption relationship with the target curved window.

[0056] After determining the target curved wall, the position of the arc center point corresponding to the arc center point of the target curved window is determined on the target curved wall, and the circle information of the target curved window is updated, replacing the circle information (radius and center) of the target curved window with the circle information of the target curved wall. Specifically, the updated radius of the target curved window is the radius of the attached target curved wall, and the updated center of the target curved window is the center of the attached target curved wall.

[0057] Given the known position of the center point of the arc of the target curved window on the corresponding arc center point on the target curved wall, the circle information corresponding to the target curved window, and the arc category to which the target curved window belongs (whether the target curved window belongs to a large arc or a small arc), calculate the starting position and ending position of the target curved window on the target curved wall based on the position of the arc center point, the chord length corresponding to the target curved window, the circle information corresponding to the target curved window, and the arc category to which the target curved window belongs. Then, draw the target curved window on the target curved wall based on the starting position and ending position.

[0058] The chord length corresponding to the target arc window remains unchanged. When calculating the starting and ending positions based on the arc center point position, the chord length corresponding to the target arc window, and the circle information corresponding to the target arc window, different calculation methods are used for different arc categories. Therefore, it is necessary to consider the arc category to which the target arc window belongs.

[0059] In the above implementation scheme, during the process of dragging the target curved window on the canvas, a target curved wall whose distance from the target curved window meets the snapping condition is identified, and the position information of the target curved window on the target curved wall is determined. Based on the determined position information and the chord length, circle information and arc type of the target curved window, the corresponding start position and end position on the target curved wall are calculated. The target curved window is drawn on the target curved wall according to the start position and end position. The target curved window can be snapped onto the target curved wall, so that the shape of the window is adapted to the wall, realizing the reasonable matching of the curved window and the curved wall, and greatly improving the design efficiency.

[0060] Specifically, determining the position of the arc center point of the target arc window on the corresponding arc center point on the target arc wall includes: determining the position of the arc center point of the target arc window on the corresponding arc center point on the target arc wall based on the intersection of the line connecting the arc center point of the target arc window and the center of the target arc wall or the extension of the line connecting the line and the target arc wall.

[0061] When determining the position of the center point of the arc corresponding to the center point of the target arc window on the target arc wall, such as Figure 3A As shown, based on the intersection of the line connecting the center point of the target curved window's arc and the center of the target curved wall with the target curved wall, the position of the center point of the corresponding arc on the target curved wall is determined. Figure 3A The intersection point 1 is the location of the arc center point.

[0062] When determining the position of the center point of the arc corresponding to the center point of the target arc window on the target arc wall, such as Figure 3B As shown, after connecting the center point of the arc of the target curved window to the center of the circle of the target curved wall, the position of the center point of the arc of the target curved window on the target curved wall is determined based on the intersection of the extension of the connecting line and the target curved wall. Figure 3B In the diagram, the intersection point 2 determined by the extended line (dashed line) is the location of the arc center point on the target arc wall.

[0063] In the above implementation process, based on the positional relationship between the target curved window and the target curved wall, the position of the center point of the arc corresponding to the target curved window on the target curved wall is determined by an appropriate method. The positional information of the target curved window on the target curved wall is calculated based on the accurate projection point, which provides a positional basis for redrawing the target curved window on the target curved wall and ensures that the curved window fits on the curved wall.

[0064] Optionally, when calculating the start and end positions of the target curved window on the target curved wall based on the position of the arc center point, the chord length corresponding to the target curved window, the circle information corresponding to the target curved window, and the arc category to which the target curved window belongs, the calculation includes:

[0065] In response to the fact that the target arc window belongs to the first type of arc window, coordinate calculations are performed based on the first angle, the second angle and the center coordinates of the target arc window to determine the first coordinate position and the second coordinate position. The first angle is the angle between the line connecting the arc center point and the center coordinates of the target arc window and the positive half axis of the X-axis. The second angle is 1 / 2 of the central angle of the target arc window.

[0066] Since the target curved window belongs to the second type of curved window, coordinate calculations are performed based on the third angle, fourth angle and center coordinates of the target curved window to determine the first coordinate position and the second coordinate position. The third angle is the angle between the line connecting the target position and the center coordinates and the positive half axis of the X-axis. The target position and the position of the arc center point are symmetrical about the center of the target curved window. The fourth angle is 360 minus 1 / 2 of the difference between the center angle of the target curved window and the center angle of the target curved window.

[0067] Determine the starting and ending positions based on the first and second coordinate positions;

[0068] Among them, arc windows whose distance from the arc center point to the chord length is less than or equal to the radius corresponding to the target arc window belong to the first type of arc window, and arc windows whose distance from the arc center point to the chord length is greater than the radius corresponding to the target arc window belong to the second type of arc window.

[0069] When calculating the starting and ending positions of the target curved window on the target curved wall, it is necessary to distinguish whether the target curved window belongs to the first type of curved window (the distance from the center point of the arc to the chord length is less than or equal to the radius corresponding to the target curved window) or the second type of curved window (the distance from the center point of the arc to the chord length is greater than the radius corresponding to the target curved window).

[0070] If the target curved window belongs to the first type of curved window, the first angle is determined based on the angle between the line connecting the determined arc center point position and the center coordinates of the target curved window and the positive half-axis of the X-axis. The second angle is determined based on half of the central angle of the target curved window. Then, coordinate calculations are performed based on the first angle, the second angle, and the center coordinates to determine the first coordinate position and the second coordinate position of the target curved window on the target curved wall.

[0071] Wherein, the first angle (angle b) = Math.atan2(y-center.y, x-center.x), the second angle (angle a) = Math.asin(chord length / (2radius)) = central angle / 2, the angle range of the second angle is: greater than 0 degrees and less than or equal to 90 degrees, the coordinates of the arc center point are (x, y), and the coordinates of the center are (center.x, center.y).

[0072] The following example illustrates the process of determining the start and end points when the target curved window belongs to the first type of curved window. For example... Figure 4AAs shown, the target curved window is located in the fourth quadrant of the current coordinate system (the right side of the X-axis is the positive half-axis, and the bottom of the Y-axis is the positive half-axis). Angle 'a' is half the central angle and is taken as a positive angle. Angle 'b' is in the fourth quadrant and is taken as a negative angle. Angle 'c' is in the fourth quadrant and is taken as a negative angle, with angle 'c' = angle 'b' + angle 'a'. Angle 'd' is in the fourth quadrant and is taken as a negative angle, with angle 'd' = angle 'b' - angle 'a'. All four angles are considered in terms of sign. Specifically, cos(angle c) is greater than 0, sin(angle c) is less than 0, cos(angle d) is greater than 0, and sin(angle d) is less than 0. For the case where the target curved window is clockwise, the x-coordinate of the starting point A is Ax = center.x + R * cos(angle b - angle a), and its y-coordinate is Ay = center.y + R * sin(angle b - angle a), where R represents the updated radius of the target curved window. The x-coordinate of endpoint B is Bx = center.x + R*cos(angle b + angle a), and its y-coordinate is By = center.y + R*sin(angle b + angle a). If the target curved window is counterclockwise, the x-coordinate of starting point B is Bx = center.x + R*cos(angle b + angle a), and its y-coordinate is By = center.y + R*sin(angle b + angle a). The x-coordinate of endpoint A is Ax = center.x + R*cos(angle b - angle a), and its y-coordinate is Ay = center.y + R*sin(angle b - angle a).

[0073] In another example, such as Figure 4BAs shown, the target arc-shaped window is located in the third quadrant of the current coordinate system (the right side of the X-axis is the positive semi-axis, and the bottom of the Y-axis is the positive semi-axis). Angle a is half the central angle and is taken as a positive angle; angle b is taken as a negative angle; angle c1 = angle b + angle a and is taken as a negative angle; angle d1 = angle b - angle a and is taken as a negative angle; angle c2 is a negative angle and its sum with angle c1 is -π; angle d2 is a negative angle and its sum with angle d1 is -π. cos(angle c1) is negative, cos(angle c2) is positive, and they are opposites of each other; sin(angle c1) is negative, sin(angle c2) is negative, and they are equal. cos(angle d1) is negative, cos(angle d2) is positive, and they are opposites of each other; sin(angle d1) is negative, sin(angle d2) is negative, and they are equal. For the target curved window that is clockwise, the x-coordinate of the starting point B is Bx = center.XR*cos(angle d2) = center.X + R*cos(angle d1) = center.X + R*cos(angle b - angle a), and its y-coordinate is By = center.y + R*sin(angle d2) = center.y + R*sin(-π - angle d1) = center.y + R*sin(angle d1) = center.y + R*sin(angle b - angle a). The x-coordinate of endpoint A is Ax = center.XR*cos(angle c2) = center.X + R*cos(angle c1) = center.X + R*cos(angle b + angle a), and its y-coordinate is Ay = center.y + R*sin(angle c2) = center.y + R*sin(-π - angle c1) = center.y + R*sin(angle c1) = center.y + R*sin(angle b + angle a). For the case where the target curved window is counter-clockwise, the x-coordinate of starting point A is Ax = center.X + R*cos(angle b + angle a), and its y-coordinate is Ay = center.y + R*sin(angle b + angle a); the x-coordinate of endpoint B is Bx = center.X + R*cos(angle b - angle a), and its y-coordinate is By = center.y + R*sin(angle b - angle a).

[0074] Based on the above calculations, the first and second coordinate positions of the target arc-shaped window belonging to the first type of arc window can be determined, which also determines the starting and ending positions.

[0075] If the target curved window belongs to the second type of curved window, the third angle is determined based on the angle between the line connecting the target position and the center coordinates and the positive half-axis of the X-axis. The target position and the position of the arc center point are symmetrical about the center of the target curved window. The fourth angle is determined based on 360 minus 1 / 2 of the difference between the angle of the center of the target curved window and the angle of the center of the target curved window. Then, coordinate calculations are performed based on the third angle, the fourth angle and the center coordinates to determine the first coordinate position and the second coordinate position of the target curved window on the target curved wall.

[0076] The third angle (angle e) = Math.atan2(Py-center.y, Px-center.x), the fourth angle (angle f) = Math.asin(chord length / (2radius)) = (360-central angle) / 2, the coordinates of the arc center point are (x, y), the coordinates of the target point P are (Px, Py), and the coordinates of the center are (center.x, center.y).

[0077] For example, such as Figure 5A As shown, the target arc-shaped window is a large arc. The target position (point P), which is symmetrical to the center point of the arc about the center, is located in the second quadrant of the current coordinate system (the right side of the X-axis is the positive half-axis, and the bottom of the Y-axis is the positive half-axis). Both angles e and f are positive angles. For the case where the target arc-shaped window is clockwise, the x-coordinate of the starting point A is Ax = center.XR*cos(π-(angle e+angle f)) = center.X+R*cos(angle e+angle f), and its y-coordinate is Ay = center.y+R*sin(π-(angle e+angle f)) = center.y+R*sin(angle e+angle f); the x-coordinate of the ending point B is Bx = center.X+R*cos(angle e-angle f), and its y-coordinate is By = center.y+R*sin(angle e-angle f). For the target curved window that is counterclockwise, the x-coordinate of the starting point B is Bx = center.X + R*cos(angle e - angle f), and its y-coordinate is By = center.y + R*sin(angle e - angle f); the x-coordinate of the ending point A is Ax = center.X + R*cos(angle e + angle f), and its y-coordinate is Ay = center.y + R*sin(angle e + angle f).

[0078] Or, such as Figure 5BAs shown, the target arc-shaped window is a large arc. The target position (point P), which is symmetrical to the center point of the arc about the center, is located in the first quadrant of the current coordinate system (the right side of the X-axis is the positive half-axis, and the bottom of the Y-axis is the positive half-axis). Both angles e and f are positive angles. For the case where the target arc-shaped window is clockwise, the x-coordinate of the starting point A is Ax = center.X + R*cos(angle e + angle f), and its y-coordinate is Ay = center.y + R*sin(angle e + angle f); the x-coordinate of the ending point B is Bx = center.X + R*cos(angle e - angle f), and its y-coordinate is By = center.y + R*sin(angle e - angle f). For the target curved window that is counterclockwise, the x-coordinate of the starting point B is Bx = center.X + R*cos(angle e - angle f), and its y-coordinate is By = center.y + R*sin(angle e - angle f); the x-coordinate of the ending point A is Ax = center.X + R*cos(angle e + angle f), and its y-coordinate is Ay = center.y + R*sin(angle e + angle f).

[0079] Based on the above calculations, the first and second coordinate positions of the target arc window belonging to the second type of arc window can be determined, which also determines the starting and ending positions.

[0080] In the above implementation scheme, the coordinates of the endpoint position of the target curved window on the curved wall are calculated by using an appropriate scheme based on the type of curved window. The curved window can be ensured to fit on the curved wall based on an accurate parameter update algorithm.

[0081] Optionally, after determining the starting and ending positions, when drawing the target curved window on the target curved wall based on the starting and ending positions, the process includes:

[0082] The first outer contour point and the first inner contour point are determined based on the starting position, and the second outer contour point and the second inner contour point are determined based on the ending position.

[0083] The first starting point angle and the first ending point angle are determined based on the first outer contour point and the second outer contour point, and multiple discrete points of the outer contour arranged clockwise are determined based on the first starting point angle and the first ending point angle.

[0084] The second starting point angle and the second ending point angle are determined based on the first inner contour point and the second inner contour point, and multiple discrete points of the inner contour arranged clockwise are determined based on the second starting point angle and the second ending point angle.

[0085] Place the starting point, multiple outer contour discrete points, the ending point, and multiple inner contour discrete points as key points in the target array, and draw the target arc window on the target arc wall based on the key points in the target array.

[0086] Given the starting point position, calculate the tangent vector at that position, and then calculate two unit vectors perpendicular to the tangent vector. Based on the coordinates of the starting point and the two unit vectors, calculate and determine the outer and inner contour points of the starting point. Here, 'top' represents the outer contour of the curved wall, and 'bottom' represents the inner contour of the curved wall.

[0087] like Figure 6 As shown, the tangent vector unv at the starting position is determined, and then the first unit vector unv1 and the second unit vector unv2 are calculated. The directions of the first and second unit vectors are opposite. After defining the positive direction, the sign of the unit vectors needs to be considered when calculating based on them. The x-coordinate top.x of the first outer contour point = unv1.x * half the wall thickness + start.x, and the y-coordinate top.y of the first outer contour point = unv1.y * half the wall thickness + start.y. For the inner contour point, the x-coordinate bottom.x of the first inner contour point = unv2.x * half the wall thickness + start.x, and the y-coordinate bottom.y of the first inner contour point = unv2.y * half the wall thickness + start.y. The calculation method for the outer and inner contour points on the endpoint side is similar and will not be described here.

[0088] After determining the first outer contour point and the first inner contour point based on the starting position, and the second outer contour point and the second inner contour point based on the ending position, for the two outer contour points, the first starting angle startTopAngle and the first ending angle endTopAngle are calculated using the Math.atan2 function based on the information of the circle's center. Taking the calculation of the first starting angle startTopAngle as an example, startTopAngle = Math.atan2(A1.y - center.y, A1.x - center.x), where (A1.x, A1.y) represent the coordinates corresponding to the first outer contour point at the starting position. After obtaining the first starting angle and the first ending angle, multiple discrete points of the outer contour arranged clockwise on the outer contour are calculated based on the first starting angle and the first ending angle.

[0089] At this stage, it is first necessary to determine whether the outer contour is clockwise or counterclockwise. If it is clockwise, the calculation is performed directly. If it is counterclockwise, the start and end points of the outer contour need to be replaced. After the replacement, startTopAngle and endTopAngle are determined. If endTopAngle is less than startTopAngle, 2π is added to endTopAngle.

[0090] When determining discrete points on the outer contour through calculation, the angle range of the corresponding arc of the outer contour is determined as endTopAngle minus startTopAngle. This angle range is divided into n equal parts, and the angle t corresponding to each part is t = startTopAngle + i(endTopAngle - startTopAngle) / n, where i takes a value greater than or equal to 0 and less than or equal to n. For angle t, taking the positive half-axis of the XY axis as an example, the corresponding coordinates on the arc are (center x + R*cos t, center y + R*sint). Based on the above calculation, multiple discrete points on the outer contour arranged clockwise can be determined.

[0091] Similarly, for the two inner contour points, the second starting angle (startBottomAngle) and the second ending angle (endBottomAngle) are calculated. After obtaining the second starting angle and the second ending angle, multiple discrete points of the inner contour arranged clockwise are calculated based on the second starting angle and the second ending angle. For a detailed explanation of the outer contour, please refer to the description of the outer contour, which will not be repeated here.

[0092] After determining multiple discrete points on the outer contour and multiple discrete points on the inner contour, identify whether the target curved window is clockwise or counterclockwise (the direction from the starting point to the ending point is clockwise or counterclockwise). If it is clockwise, first add the starting point to the target array, then add the multiple outer contour discrete points in ascending order, then add the ending point to the target array, and finally add the multiple inner contour discrete points in descending order. Draw the points in the target array sequentially, ensuring they are connected end-to-end, to draw the target curved window. If it is counterclockwise, first add the ending point to the target array, then add the multiple outer contour discrete points in ascending order, then add the starting point to the target array, and finally add the multiple inner contour discrete points in descending order. Draw the points in the target array sequentially, ensuring they are connected end-to-end, to draw the target curved window. The drawn target curved window can be understood in terms of shape as part of a target curved wall.

[0093] In the above implementation scheme, multiple outer contour discrete points and multiple inner contour discrete points are determined based on the starting point and ending point positions. The outer contour discrete points and inner contour discrete points are used as key points to draw the target arc-shaped window. The target arc-shaped window can be redrawn on the target arc-shaped wall, so that the target arc-shaped window is adapted to the wall, and the reasonable matching between the arc-shaped window and the arc-shaped wall is achieved.

[0094] The following describes a scheme for moving a target curved window on a target curved wall. Optionally, when controlling the movement of the target curved window on the target curved wall in response to a movement interaction input to update the position of the target curved window, the following steps are included:

[0095] In response to interactive input of dragging the center point of the target curved window on the target curved wall, update the start and end positions of the target curved window; based on the updated start and end positions, redraw the target curved window on the target curved wall to control the movement of the target curved window and update the position of the target curved window on the target curved wall.

[0096] After selecting the target curved window, dragging it allows you to move it on the target curved wall. The dragging point is the center point of the curved window's arc; this dragging operation is the interactive input for moving the target curved window. Based on this interactive input, the start and end positions of the target curved window on the target curved wall are updated. During this process, the shape of the target curved window remains unchanged; only its position on the target curved wall changes.

[0097] After determining the updated start and end positions based on mobile interactive input, the target curved window is redrawn on the target curved wall based on the updated start and end positions, and the position of the target curved window on the target curved wall is updated to respond to mobile interactive input to control the movement of the target curved window on the target curved wall. For example... Figure 7 As shown, in the initial state, the target curved window is attached to the first position of the target curved wall. Based on the movement interaction input of dragging the target curved window, the position of the target curved window on the target curved wall is adjusted so as to update the position of the target curved window while maintaining its shape.

[0098] It should be noted that during the dragging of the target curved window, the starting and ending positions of the target curved window on the target curved wall are updated in real time. Based on these updated starting and ending positions, the target curved window is redrawn on the target curved wall to maintain its display during movement. The process of redrawing the target curved window based on the starting and ending positions will not be further elaborated here.

[0099] Optionally, if the perimeter of the target curved wall is greater than half the perimeter of the circle it is in, the method further includes: in response to the target curved window stopping moving on the target curved wall, identifying whether the two endpoints of the target curved wall are in the target curved window; and in response to the two endpoints of the target curved wall being in the target curved window, adjusting the category of the target curved window.

[0100] Specifically, if the target curved window is a second type of curved window where the distance from the center point of the arc to the chord is greater than the radius of the target curved window, the target curved window is adjusted to a first type of curved window where the distance from the center point of the arc to the chord is less than the radius of the target curved window; if the target curved window is a first type of curved window, the target curved window is adjusted to a second type of curved window.

[0101] For the specific case where the target curved wall is a large arc (i.e., the circumference of the target curved wall is greater than half the circumference of the corresponding circle), since the target curved window moves and continuously adjusts its position on the target curved wall, there is a possibility that the target curved window will cover the gap in the curved wall after updating its position. Therefore, a judgment process is required. That is, when the target curved window stops moving on the target curved wall, it is determined whether the target curved window covers the gap in the curved wall. If it covers the gap in the curved wall, the target curved window is reclassified. For the case where the target curved window is a second-class curved window (the distance from the arc center point to the chord length is greater than the radius corresponding to the target curved window), the target curved window is adjusted to a first-class curved window (the distance from the arc center point to the chord length is less than the radius corresponding to the target curved window). For the case where the target curved window is a first-class curved window (the distance from the arc center point to the chord length is less than the radius corresponding to the target curved window), the target curved window is adjusted to a second-class curved window. This can be simply understood as follows: For large arched windows that cover the gaps in the curved wall, adjust them to small arched windows; for small arched windows that cover the gaps in the curved wall, adjust them to large arched windows. For example, such as... Figure 8 As shown, the large curved window moves on the curved wall. When it stops moving, the large curved window covers the gap in the curved wall. At this point, the large curved window is adjusted to become a small curved window that attaches to the curved wall. Consider a special case: if the distance from the center point of the arc to the chord length is equal to the radius corresponding to the target curved window, then the target curved window also belongs to the first type of curved window. When adjusting, the starting and ending positions are interchanged to adjust the curved window, or the arc direction from the starting point to the ending point is adjusted to adjust the curved window.

[0102] When adjusting a small arc window to a large arc window, or vice versa, since the starting and ending positions are known, the arc window can be redrawn in the manner described above. Alternatively, if the starting and ending positions are known, the new arc window can be determined by directly changing the clockwise or counterclockwise direction from the starting point to the ending point.

[0103] In determining whether a target curved window covers a gap in a curved wall, it can be identified whether the two endpoints of the target curved wall are within the target curved window. If both endpoints are within the target curved window, then it is determined that the target curved window covers the gap in the curved wall. For a specific endpoint of the target curved wall, the following method can be used to identify whether that endpoint is within the target curved window:

[0104] The first and second vectors are determined based on the arc center point of the target arc window and the two endpoints of the target arc window; the third vector is determined based on the arc center point of the target arc window and the center of the circle; and the fourth vector is determined based on the arc center point of the target arc window and the endpoint of the target arc wall.

[0105] The first value is determined by multiplying the value of the cross product of the first vector and the fourth vector by the cross product of the first vector and the third vector.

[0106] The second value is determined by multiplying the value of the cross product of the second vector and the fourth vector, and the value of the cross product of the second vector and the third vector.

[0107] In response to a negative first or second value, determine that the endpoint of the target curved wall is within the target curved window.

[0108] When determining whether a point is on the left or right side of a line, the cross product operation can be used. If two points (such as point A and point B) are on opposite sides of line segment CD, then vector 1 is determined based on line segment CD, vector 2 is determined based on CA, and vector 3 is determined based on CB. The product of the cross product of vector 1 and vector 2 and the cross product of vector 1 and vector 3 will definitely be less than 0.

[0109] like Figure 9 As shown, the first vector is determined by the arc center point P and the starting point start of the target curved window; the second vector is determined by the arc center point P and the ending point end of the target curved window; and the third vector is determined by the arc center point P and the center O of the circle. If there exists a point E (the endpoint of the target curved wall) on the arc corresponding to P and start, then points E and O must be on opposite sides of the line containing vector Pstart (the first vector). That is, the cross product of vector Pstart and vector PE (the fourth vector) multiplied by the cross product of vector Pstart and vector PO (the third vector) will always be negative. Similarly, if there exists a point E (the endpoint of the target curved wall) on the arc corresponding to P and end, then points E and O must be on opposite sides of the line containing vector Pend (the second vector). That is, the cross product of vector Pend and vector PE (the fourth vector) multiplied by the cross product of vector Pend and vector PO (the third vector) will always be negative.

[0110] Based on the above, it can be determined that for a certain endpoint of the target curved wall, if either the first value (the product of the first vector's cross product with the fourth vector and the first vector's cross product with the third vector) or the second value (the product of the second vector's cross product with the fourth vector and the second vector's cross product with the third vector) is negative, then that endpoint of the target curved wall is determined to be within the target curved window. The same judgment strategy is used to identify whether the other endpoint of the target curved wall is within the target curved window.

[0111] In the above implementation scheme, when the target curved window updates its position on the target curved wall, it is identified whether the target curved window covers the gap in the curved wall when the target curved window stops moving. If the target curved window covers the gap in the curved wall, the target curved window is reclassified and a new curved window is determined. This intelligently handles the special case of large curved walls through a dynamic large and small arc switching mechanism, solving the problem of large curved wall gaps being covered and enhancing applicability.

[0112] The following describes a scheme for updating the shape of a curved window. Optionally, when adjusting the position of the first endpoint on the target curved wall in response to the update input to update the shape of the target curved window, the following steps are included:

[0113] In response to the update input of dragging the first endpoint of the target curved window to change its position on the target curved wall, update the chord length of the target curved window and the position information of the first endpoint; update the arc center point of the target curved window according to the position information of the first endpoint and the initial position information of the second endpoint; determine the category of the target curved window according to the distance between the arc center point and the chord length; redraw the target curved window on the target curved wall according to the category of the target curved window, the position information of the first endpoint and the initial position information of the second endpoint, so as to adjust the position of the first endpoint on the target curved wall and update the shape of the target curved window.

[0114] After selecting the first endpoint (start or end point) of the target curved window, drag the first endpoint to update its position on the target curved wall. Since the first endpoint's position is updated while the second endpoint remains stationary, the chord length corresponding to the target curved window changes. Based on the dragging first endpoint and the other endpoint (second endpoint), determine the target curved window's position point (arc center point) to update the arc center point of the target curved window according to the position information of the first endpoint and the initial position information of the second endpoint. After updating the arc center point and chord length, calculate the distance from the arc center point to the chord length. Based on the calculated distance and the current radius of the target curved window, identify the category of the target curved window. Then, based on the category of the target curved window, the position information of the first endpoint, and the initial position information of the second endpoint, redraw the target curved window on the target curved wall.

[0115] Specifically, when updating the arc center point of the target arc window based on the position information of the first endpoint and the initial position information of the second endpoint, the coordinates of the chord center F are determined based on the position information of the first endpoint and the initial position information of the second endpoint. Then, based on the coordinates of the center O and the coordinates of the chord center F, the unit vector unv3 in the OF direction is calculated. The coordinates of the arc center point are determined based on the coordinates of the center O, the unit vector unv3, and the radius R. For example, the abscissa of the arc center point P is Px = center.x + unv3.x * R, and the ordinate of the arc center point P is Py = center.y + unv3.y * R.

[0116] After determining the arc center point and chord length, the distance from the arc center point to the chord length is calculated. This distance is compared with the radius of the target arc window. If the distance is greater than the radius, it is determined to be a large arc window; if it is less than or equal to the radius, it is determined to be a small arc window. With the arc window type determined, the target arc window is redrawn on the target arc wall based on the position information of the first endpoint and the initial position information of the second endpoint. The redrawing process is not described here. Because the first endpoint updates its position in real time while being dragged, it is necessary to determine the chord length, update the arc center point, and redraw the target arc window in real time to maintain the display of the target arc window during shape changes.

[0117] After dragging the first endpoint stops, the shape update of the target curved window ends. At this point, the target curved window attached to the target curved wall is the curved window after the shape change. For example, Figure 10 As shown, by dragging one end point and changing the shape of the target curved window, the small curved window attached to the curved wall can be adjusted into a large curved window.

[0118] In the above implementation scheme, the target curved window is updated by updating the position of the endpoint of the target curved window on the curved wall. The window shape can be adjusted in real time based on the movement of the drag point, and the curved window shape can be edited and updated intuitively.

[0119] This application also provides an arc-shaped window interaction device, such as... Figure 11 As shown, it includes:

[0127] The calculation submodule is used to calculate the starting position and ending position of the target arc window on the target arc wall based on the position of the arc center point, the chord length corresponding to the target arc window, the circle information corresponding to the target arc window, and the arc category to which the target arc window belongs;
