DETAILED DESCRIPTION

[0012] To make the objectives, technical solutions and advantages of embodiments of the present application clearer, the technical solutions of the present application will be described below in detail with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0013] Season pass systems are becoming more common in modern games, providing a structured reward mechanism that incentivizes players to continue playing over a period of time. A common interaction design is a swipe list that displays images and text information of pass prizes on the list.

[0014] In the related art, the season pass system of some game products is provided with a time limit, requiring users to complete corresponding tasks within a specified time to obtain rewards. However, for the season pass system without a time limit, the product needs to provide an operation interface for users to access historical season passes. For the historical season pass interface, there are deficiencies in visual presentation and user interaction experience, and there is a lack of effective visual enhancement means.

[0015] Based on this, the model rendering method, device and electronic device provided by an embodiment of the present application can be applied to the entry presentation process of multiple subsystems in a game.

[0016] Referring to Figure 1 , first, a model rendering method provided by an embodiment of the present application is introduced. A graphical user interface is provided by a terminal device. The method includes the following steps: Step S102, a rectangular model and a texture map corresponding to the rectangular model are obtained; the rectangular model has multiple vertices, and the texture map is used to make the rectangular model display a longitudinal track.

[0017] The above rectangular model is usually a planar model. The surface of the planar model is composed of primitives connected by a plurality of vertices. The rectangular model has a corresponding texture map. In order to make the rectangular model display a longitudinal track effect, the texture map usually includes the texture of the longitudinal track. The longitudinal track can be a straight track, a polyline track such as a lightning-shaped track as shown in Figure 2 , or other tracks with curvature, which are not limited here.

[0018] Step S104, based on the pre-determined shape transformation parameter, the positions of the plurality of vertices of the rectangular model are transformed to form a trapezoidal model connected by the vertices in the transformed positions; the shape transformation parameter is used to map the rectangle to the trapezoid.

[0019] Due to the lack of expression of normal space perspective, the longitudinal track in the planar model needs to be artificially enhanced to enhance the expression of near large and far small, that is, false perspective. If the false perspective effect is directly realized by using the trapezoidal model, because of the characteristics of the trapezoid being narrow at the top and wide at the bottom, the texture coordinates are not evenly distributed, resulting in that the longitudinal track with a polyline appears as a curved shape on the trapezoid, as shown in Figure 3 , and also causes the longitudinal track with curvature to be deformed, resulting in poor display effect. Therefore, the positions of the vertices of the rectangular model are transformed by the shape transformation parameter, and the vertices connected in the transformed positions form a trapezoid. At this time, the longitudinal texture coordinates of the rectangular model after the position transformation of the vertices become uneven, and the rendering effect obtained by rendering the rectangular model can conform to the perspective effect under the normal perspective condition.

[0020] The shape transformation parameter is usually generated based on the rectangle and the trapezoid, and is used to map the rectangle to the trapezoid. In actual application, it can be realized by matrix transformation. The matrix representing the rectangle and the matrix representing the trapezoid can be established respectively, and then the matrix corresponding to the product of the matrix of the trapezoid and the inverse matrix of the rectangle is taken as the shape transformation parameter. For each vertex of the rectangular model, the shape transformation parameter can be applied to the position coordinate parameter of the vertex to obtain the updated position coordinate parameter of the vertex, thereby determining the transformed positions of the plurality of vertices.

[0021] Step S106, based on the transformed positions of the plurality of vertices and the texture map, the trapezoidal model is rendered to display the rendered longitudinal track in the graphical user interface.

[0022] After the positions of the vertices are transformed, the corresponding texture map of the rectangular model can be sampled according to the texture map coordinates of each vertex to obtain the color parameters corresponding to the vertices, and then the rectangular model is rendered. Finally, the longitudinal track is displayed. Due to the transformation of the positions of the vertices, the longitudinal track in the graphical user interface presents a perspective effect, giving the player a visual experience with impact.

[0023] The model rendering method, the rectangular model and the texture map corresponding to the rectangular model are obtained; the rectangular model has a plurality of vertices, and the texture map is used to display a longitudinal track for the rectangular model; a plurality of vertices of the rectangular model are subjected to position transformation processing based on a predetermined shape transformation parameter, so that the vertices after position transformation are connected to form a trapezoidal model; the shape transformation parameter is used to map the rectangle to the trapezoid; the trapezoidal model is rendered based on the positions after transformation of the plurality of vertices and the texture map, so as to display the rendered longitudinal track in the graphical user interface. This way of displaying the track association with perspective effect has visual impact and can easily arouse the exploration interest of the players, thereby improving the game retention rate to a certain extent and improving the utilization rate of game system resources.

[0024] In a specific embodiment, the shape transformation parameter can be determined in the following way: (1) Obtain a preset rectangle and a trapezoid corresponding to the rectangle.

[0025] The rectangle can be a square or a rectangle. The trapezoid corresponding to the rectangle is usually formed by reducing the upper side of the rectangle. As shown in Figure 4 , points A (1, 0), B (0, 0), C (0, 1), and D (1, 1) in the two-dimensional Cartesian coordinate system are the vertices of the rectangle, and the gray part is the internal area of the rectangle. As shown in Figure 5 , points A1 (1, 0), B1 (0, 0), C1 (2 / a, 1), and D1 (1-2 / a, 1) in the coordinate system are the vertices of the trapezoid, and the gray part is the internal area of the trapezoid. At this time, the upper base of the trapezoid is determined by the length of the side of the rectangle minus the variable a, that is, the length of the upper base of the trapezoid = the length of the segment C1D1 = 1-a, and a takes a value in the range (0, 1). The length of the upper base of the trapezoid can also be set to a fixed value according to requirements, which is not limited here.

[0026] (2) Determine a first matrix based on the rectangle; the first matrix is used to describe the positional relationship of the four vertices of the rectangle.

[0027] In order to obtain the first matrix, the coordinates of A, B, C, and D can be substituted into the following linear equation:

[0028] Wherein, the coordinates of point A are (x1, y1), the coordinates of point B are (x2, y2), the coordinates of point C are (x3, y3), and the coordinates of point D are (x4, y4).

[0029] The solution is obtained

[0030] Substitute λ, μ, τ, and A, B, C, and D coordinates into the following matrix

[0031] The first matrix (denoted as matrix A) is obtained:

[0032] (3) Calculate the inverse matrix of the first matrix.

[0033] After the first matrix is calculated, the inverse operation needs to be performed on the first matrix. When the first matrix is the above-mentioned matrix A, the inverse result is as follows:

[0034] (4) Determine the second matrix based on the trapezoid; the second matrix is used to describe the positional relationship of the four vertices of the trapezoid.

[0035] Similar to the way of obtaining the above-mentioned first matrix, A1, B1, C1, and D1 coordinates are substituted into the following linear equations

[0036] Wherein, the coordinates of A1 point are (x1, y1), the coordinates of B1 point are (x2, y2), the coordinates of C1 point are (x3, y3), and the coordinates of D1 point are (x4, y4).

[0037] The solution obtained is:

[0038] Substitute λ, μ, τ, and A1, B1, C1, and D1 coordinates into the following matrix:

[0039] The second matrix (denoted as matrix B) is obtained:

[0040] (5) Multiply the second matrix and the inverse matrix of the first matrix to obtain the third matrix.

[0041] As mentioned above, the first matrix can be written as matrix A, and the second matrix can be written as matrix B. Let the transformation matrix be C, because:

[0042] Then according to the properties of matrix multiplication, the following is obtained:

[0043] Substitute B and the inverse matrix of A calculated in the above into the following result:

[0044] (6) Determine the shape transformation parameter based on the third matrix.

[0045] In a specific implementation, the third matrix can be directly stored as the shape transformation parameter. Alternatively, each element of the third matrix can be stored in the form of a character to obtain the shape transformation parameter. The specific setting can be determined according to requirements, which is not limited herein.

[0046] The following embodiments provide an implementation manner of performing position transformation processing on a plurality of vertices of a rectangular model based on a predetermined shape transformation parameter to obtain transformed positions of the plurality of vertices.

[0047] In actual application, a shape transformation matrix needs to be constructed based on the predetermined shape transformation parameter. As described above, the shape transformation parameter can have a variable, and a variable value of the variable can be set in advance by relevant personnel. In material calculation in actual application, the variable a in the shape transformation parameter can be set as ShrinkPercent (S) as a shrinkage rate of the top of the trapezoid, and the value is 0-1. Further, the shape transformation matrix not including the variable is constructed based on the shape transformation parameter and the set variable value. When the shape transformation parameter includes nine values, three row vectors can be first constructed, and then the shape transformation matrix is constructed based on the three row vectors. Then, the transformed position parameters of the plurality of vertices can be obtained based on the initial position parameters of the plurality of vertices and the shape transformation matrix.

[0048] The initial position parameters include X-axis coordinate values, Y-axis coordinate values and Z-axis coordinate values corresponding to the initial positions of the vertices in the Cartesian space. Because the rectangular stretching into a trapezoid is a two-dimensional transformation, only x and y of the vertex coordinates x, y and z participate in the calculation.

[0049] For each vertex of the plurality of vertices, the homogeneous coordinates corresponding to the vertex are generated based on the X-axis coordinate value and the Y-axis coordinate value in the initial position parameter of the vertex. In a specific implementation, the z=1 component can be added. Then, the shape transformation matrix is applied to the homogeneous coordinates, that is, the shape transformation matrix is multiplied by the homogeneous coordinates corresponding to the vertex to obtain updated homogeneous coordinates corresponding to the vertex. In a specific implementation, the transformed position parameter of the vertex is determined based on the updated homogeneous coordinates of the vertex, and the transformed position parameter includes the coordinates corresponding to the transformed position of the vertex in the Cartesian space.

[0050] The updated homogeneous coordinates correspond to the X-axis coordinate value, the Y-axis coordinate value and the Z-axis coordinate value of the transformed position of the vertex in the homogeneous space. In the process of determining the transformed position parameter of the vertex, the perspective division needs to be performed first, that is, the X-axis coordinate value and the Y-axis coordinate value in the updated homogeneous coordinates of the vertex are divided by the Z-axis coordinate value in the updated homogeneous coordinates to obtain the calculated X-axis coordinate value and the calculated Y-axis coordinate value. Based on the calculated X-axis coordinate value and the calculated Y-axis coordinate value, the transformed position parameter of the vertex is determined. The calculated X-axis coordinate value and the calculated Y-axis coordinate value are replaced by the original X-axis coordinate value and the original Y-axis coordinate value of the vertex, that is, the transformed position parameter of the vertex is obtained. After the transformation of the vertex, the display effect of the material is as shown in Figure 6

[0051] In an embodiment, the rectangular model and the corresponding texture map are included in the interface rendering resource of the specified system. In response to the entry display triggering event of the specified system, the interface rendering resource of the specified system is obtained. When the specified system includes multiple subsystems, the interface rendering resource usually also includes the identification model corresponding to each subsystem. The identification model can be a three-dimensional model or a planar model. The identification model also usually has a corresponding texture map, color parameter, etc., which will not be described here.

[0052] The specified system can be various, such as the pass system and the browsing system of game elements as described above, which will not be limited here. The specified system includes multiple subsystems, and the establishment time of different subsystems is usually different, and the content is also different. When the specified system is a pass system, different subsystems can correspond to passes established at different times.

[0053] The entry display triggering event of the specified system can be automatically generated by the game system or generated by the game operation of the player. For example, after the player opens the game client on the terminal device, the game system can generate the entry display triggering event of the specified system after a set time; or a control for triggering the entry display of the specified system can be pre-set in the graphical user interface, and the player triggers the control to consider that the entry display triggering event of the specified system is generated. The specific setting can be made according to the demand, which will not be limited here. The interface rendering resource of the specified system can be pre-stored in the terminal device or obtained in real time by the terminal device from the game server.

[0054] When the identification corresponding to at least part of the subsystems is displayed in the graphical user interface, these identifications are usually considered to be triggerable as the entry of the corresponding subsystem. The player can trigger a certain identification through a human-computer interaction device such as a mouse, a touch screen, etc. Here, for the convenience of writing, it is called "first identification". After the first identification is triggered, the graphical user interface displays the subsystem corresponding to the first identification.

[0055] ​After the interface rendering resource is acquired and the positions of the vertices of the rectangular model are changed, a target interface corresponding to a specified system is rendered based on the positions of the vertices after transformation, the texture map, and the identification model corresponding to each subsystem, to display the rendered longitudinal track and the identification corresponding to at least part of the subsystems in the target interface. The identification corresponding to at least part of the subsystems is displayed in association with the longitudinal track.

[0056] The number of the identifications of the subsystems displayed in the graphical user interface is usually preset. When the number of the subsystems is small, the identifications of all the subsystems can be displayed in the graphical user interface. When the number of the subsystems is large, only part of the identifications of the subsystems can be displayed in the graphical user interface. In this case, when the establishment times of the subsystems are different, the identifications of the subsystems that can be displayed in the graphical user interface, i.e., the identifications corresponding to at least part of the subsystems, can be determined based on the order of the establishment times of the subsystems. For example, the identifications corresponding to the subsystems with establishment times close to the current time can be determined as the identifications that need to be displayed in the graphical user interface.

[0057] The identification model corresponding to the subsystem can be used to generate the identification displayed in the graphical user interface. After the identifications that need to be displayed in the graphical user interface are determined, the initial positions of the identification models corresponding to the identifications can be determined. The identifications can be displayed above the longitudinal track, or on the side of the longitudinal track, etc. The identifications can also be displayed at the set positions of the longitudinal track, such as the corners of the polyline track as shown in the figure. The display positions of the identification models and the rectangular model can be preset according to the desired display effect. Figure 2

[0058] In the above graphical user interface, the identifications of the subsystems are displayed in association with the longitudinal track. The player can generate an update instruction by performing an upward or downward sliding operation on the touch screen, or an upward or downward scrolling of the mouse wheel, to control the display scrolling effect of the longitudinal track, while the relative positions of the identifications of the subsystems and the longitudinal track usually remain unchanged and are scrolled together. When the longitudinal track is a polyline or has a curvature, the identifications of the subsystems can be controlled to scroll along the longitudinal track.

[0059] In a specific implementation, in response to an update instruction for the graphical user interface, the moving parameters of the longitudinal track are first determined, and the updated display positions of the identification models of at least part of the subsystems are determined. The moving parameters usually include a moving direction and a moving distance. The moving direction usually corresponds to the rolling direction of the scroll wheel or the sliding direction of the sliding operation. For example, if the sliding direction of the sliding operation is upward along the screen, the moving direction of the track is also upward along the screen. The moving direction is usually proportional to the sliding distance of the sliding operation, or proportional to the rolling angle of the scroll wheel.

[0060] ​The update instruction is triggered by rolling the scroll wheel of the mouse connected to the terminal device, and the update instruction includes the rolling distance of the scroll wheel. For each of the identification models of the at least part of the subsystems, a moving distance of the identification model needs to be determined based on the rolling distance of the scroll wheel and a moving direction corresponding to the identification model. The moving direction of the identification model can be a longitudinal direction, that is, consistent with the moving direction of the track, or a direction along the broken line direction or curvature direction of the track, which is not limited here.

[0061] The longitudinal moving distance of the identification model is usually the same as the moving distance of the longitudinal track. The moving distance of the identification model in the longitudinal direction can be determined based on the rolling distance of the scroll wheel and a preset scale value, and then the moving distance of the identification model on the plane can be determined based on the moving direction of the identification model. Further, the initial update position can be determined based on the initial position and the moving distance of the identification model. Since the longitudinal track is displayed with a perspective effect, in order to keep the relative position of the longitudinal track and the identification model unchanged, the initial update position also needs to be positionally transformed based on the shape transformation parameter. The transformation process is similar to the processing method of the vertex of the rectangular model, which is not limited here. Further, the processed position can be determined as the updated display position of the identification model.

[0062] Further, the graphical user interface needs to be rendered again based on the transformed positions of the plurality of vertices, the moving parameter, the texture map, and the updated display position of the identification model of the at least part of the subsystems, and the display content of the graphical user interface is updated. Specifically, after the moving parameter of the vertex is determined, the texture map coordinate of the vertex needs to be updated so that the longitudinal track in the rectangular model rendered again presents the effect of scrolling with the update instruction generated by the player.
