[0024] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other.

[0025] In order to make the angles between the segments on the original spline more standardized and facilitate the management of the effects of scene elements generated based on splines in the virtual scene, an embodiment of the present application provides a spline data processing method, which calculates the current angle of the current spline segment through the normal directions of the starting points and the normal directions of the end points of multiple spline segments on the original spline, and then determines the corresponding target angle from the preset target angle array, and adjusts the current angle to the corresponding target angle, and continues to adjust the current angle of the next spline segment until the angle adjustment of all spline segments is completed to obtain the target spline, so that the scene elements generated based on the target spline on the basis of truly reflecting the line shape are more standardized and visually more unified, reducing the difficulty of later modification and optimization.

[0026] The following is a detailed explanation of a spline data processing method provided in an embodiment of the present application through specific examples in conjunction with the accompanying drawings. Figure 1 One of the flow charts of a spline data processing method provided in an embodiment of the present application; Figure 2 A schematic diagram of an original spline provided in an embodiment of the present application; Figure 1 As shown, the method includes: S101: Obtain the normal directions of the start points and the normal directions of the end points of multiple spline segments on an original spline.

[0027] In this embodiment, during the virtual scene development process, the underlying data of scene elements in the virtual scene are defined by primitive splines. The scene elements may be roads, rivers, mountains, glaciers, and the like.

[0028] For example, the geographic coordinates of multiple points on the road in the virtual scene are obtained and stored as a position file. The position file is read using the three-dimensional computer graphics software Houdini, and the multiple points are connected in the order of the geographic coordinates to obtain the original spline. Figure 2 As shown, the original spline includes multiple points, among which the blue points are points.

[0029] The original spline has multiple spline segments, and the start point and end point of each spline segment both store normal directions, so that the normal directions of the start point and the end point of each spline segment can be obtained.

[0030] S102: Calculate a current angle of the current spline segment according to the normal direction of the starting point and the normal direction of the end point of the current spline segment among the multiple spline segments.

[0031] S103 : Determine a target angle corresponding to the current spline segment from a preset target angle array according to the current angle of the current spline segment, and adjust the current angle of the current spline segment to the corresponding target angle.

[0032] The preset target angle array includes: multiple preset angles.

[0033] Specifically, a for loop is performed on each spline segment on the original spline, and the number of loops is the number of spline segments. It can be understood that the first loop process is to process the first spline segment among the multiple spline segments, and the current angle of the first spline segment is calculated and adjusted. Then, a second loop process is performed to continue processing the second spline segment among the multiple spline segments, until the last loop process is performed, that is, the last spline segment among the multiple spline segments is processed.

[0034] Therefore, the current spline segment is any one of the multiple spline segments. First, the current angle of the current spline segment is calculated, and then the target angle corresponding to the current spline segment is determined from the preset target angle array, and the current angle of the current spline segment is adjusted to the corresponding target angle.

[0035] Optionally, before determining the target angle corresponding to the current spline segment from a preset target angle array based on the angle of the current spline segment, the method further includes: According to the preset angle deviation, a plurality of angles in the angle arithmetic progression are obtained as a plurality of preset angles, wherein the angle difference between adjacent angles in the angle arithmetic progression is the preset angle deviation.

[0036] Specifically, the angle deviation is predetermined and an angle arithmetic progression is generated. The multiple angles in the angle arithmetic progression are used as multiple preset angles to obtain a preset target angle array.

[0037] For example, if the preset angle deviation is 15, the range of the generated angle arithmetic sequence target_angles is {0-360}, which is specifically expressed as: target_angles={15,30,45,60,75,90,105,120,135,150,165,180,195,210,225,240,255,270,285,300,315,330,345,360}.

[0038] Based on the multiple angles in the angle arithmetic progression target_angles, multiple preset angles in the preset target angle array are determined, resulting in a preset target angle array. Thus, based on the current angle of the current spline segment, the target angle corresponding to the current spline segment can be determined from the preset target angle array. It should be noted that the preset angle deviation can be set to a multiple of 15, such as 30 or 45, without limitation. The corresponding angle arithmetic progression is then generated, resulting in a corresponding preset target angle array.

[0039] Optionally, according to the current angle of the current spline segment, a preset angle closest to the current angle of the current spline segment is determined from an array of preset target angles as the target angle.

[0040] Specifically, if the preset angles in the preset target angle array are {15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360}, and if the current angle of the current spline segment is 199, then the target angle of the current spline segment is determined to be 195, and the current angle 199 of the current spline segment is adjusted to the corresponding target angle 195. Similarly, if the current angle of the current spline segment is 169, then the target angle of the current spline segment is determined to be 165, and the current angle 169 of the current spline segment is adjusted to the corresponding target angle 165.

[0041] S104 , recalculating and adjusting the angle of the next spline segment to a corresponding angle in the preset target angle array according to the normal direction of the starting point and the normal direction of the end point of the next spline segment among the multiple spline segments.

[0042] S105: Determine a spline when the angles of the plurality of spline segments are adjusted as a target spline.

[0043] The target spline is used to generate line-shaped scene elements in the virtual scene.

[0044] Specifically, since the current angle of the current spline segment is adjusted to the corresponding target angle, the end point of the current spline segment changes. Since the end point of the current spline segment is the starting point of the next spline segment, this also affects the normal direction of the starting point and the normal direction of the end point of the next spline segment. Therefore, in the next loop, it is necessary to determine the normal direction of the starting point and the normal direction of the end point of the next spline segment and calculate the angle of the next spline segment in the next loop.

[0045] Similarly, according to the angle of the next spline segment, the target angle corresponding to the next spline segment is determined from the preset target angle array, and the current angle of the next spline segment is adjusted to the corresponding target angle.

[0046] This loop continues until all the spline segments have been adjusted, resulting in a target spline. The target angles of each spline segment on the target spline are all preset angles in the preset target angle array. This creates a more visually unified virtual scene based on the target spline, with the line-shaped scene elements being more uniform.

[0047] In summary, an embodiment of the present application provides a spline data processing method, the method comprising: obtaining the normal directions of the start points and the normal directions of the end points of multiple spline segments on an original spline, calculating the current angle of the current spline segment based on the normal directions of the start point and the end point of the current spline segment among the multiple spline segments, determining the target angle corresponding to the current spline segment from a preset target angle array based on the current angle of the current spline segment, and adjusting the current angle of the current spline segment to the corresponding target angle, wherein the preset target angle array includes: multiple preset angles, recalculating and adjusting the angle of the next spline segment to the corresponding angle in the preset target angle array based on the normal directions of the start point and the end point of the next spline segment among the multiple spline segments, and finally determining the spline when the angles of the multiple spline segments are all adjusted as the target spline, wherein the target spline is used to generate line-shaped scene elements in a virtual scene. The method of the present application determines the target angle corresponding to the current spline segment based on a preset target angle array. After the angle adjustment of the current spline segment is completed, the angle of the next spline segment is continued to be processed to finally obtain the target spline, so that the target angles of each spline segment on the target spline are all preset angles in the preset target angle array. Based on the target spline, which truly reflects the line shape, the generated scene elements are more standardized and visually more unified, which reduces the difficulty of later modification and optimization.

[0048] The embodiment of the present application also provides another possible implementation of the spline data processing method by obtaining the normal direction of the starting point and the normal direction of the end point. Figure 3 The second flow chart of a spline data processing method provided in the embodiment of the present application is as follows: Figure 3 As shown, the normal directions of the start points and end points of multiple spline segments on the original spline are obtained, including: S201: Obtain normal directions of multiple control points on the original spline.

[0049] S202. Read the normal direction of the first control point at the starting point and the normal direction of the second control point at the end point of each spline segment from the normal directions of the multiple control points, and use them as the normal direction of the starting point and the normal direction of the end point of each spline segment, respectively.

[0050] In this embodiment, there are multiple control points on the original spline, and each control point stores a corresponding normal direction. Since the starting point and end point of each spline segment are both control points, the normal direction of the first control point at the starting point of each spline segment and the normal direction of the second control point at the end point of each spline segment are used as the normal direction of the starting point and the normal direction of the end point of each spline segment, respectively.

[0051] In this embodiment, the normal directions of the start point and the end point of each spline segment are determined by reading the normal directions of the multiple control points, so as to process each spline segment.

[0052] The embodiment of the present application also provides another possible implementation of the spline data processing method by obtaining the normal directions of multiple control points. Figure 4 The third flow chart of a spline data processing method provided in an embodiment of the present application is as follows: Figure 5 This is a schematic diagram of the normal direction of multiple control points provided in an embodiment of the present application. Figure 4 As shown, get the normal direction of multiple control points on the original spline, including: S301 : Sampling an original spline according to a preset spacing to obtain a plurality of control points on the original spline.

[0053] In this example, the Resample node in Houdini software is used to sample the original spline at a preset spacing, obtaining multiple control points on the original spline. The preset spacing can be set to 20, 25, or 35 units (meters), but this is not a limitation. It should be noted that the start and end points of the original spline are also control points.

[0054] S302: Segment the original spline according to the multiple control points to obtain multiple spline segments.

[0055] Specifically, the ConvertLine node in Houdini software is used to segment the original spline according to multiple control points to obtain multiple spline segments.

[0056] It should be noted that the length of each spline segment is less than or equal to the preset spacing. For example, the end point of the last spline segment of the original spline is the last control point, and the starting point is the previous control point adjacent to the last control point. If the interval between the end point and the starting point of the last spline segment is the preset spacing, the length of the last spline segment is equal to the preset spacing. If the interval between the end point and the starting point of the last spline segment is less than the preset spacing, the length of the last spline segment is less than the preset spacing.

[0057] S303: Acquire and store the normal directions of multiple control points.

[0058] The normal direction of each control point is the vector direction of the spline segment before each control point.

[0059] Specifically, the OrientAlongCurve node in Houdini software is used to take the vector direction of the spline segment before each control point as the normal direction of the control point, such as Figure 5 As shown, four spline segments are shown, including control point A, control point B, control point C and control point D. The dotted lines are the vector directions of each spline segment and also the normal directions of each control point. It should be noted that since control point A is the starting point of the original spline, the normal direction of control point A is the vector direction of the first spline segment, and the normal direction of control point B is also the vector direction of the first spline segment.

[0060] In the method provided in the embodiment of the present application, the original spline is sampled according to a preset spacing to obtain multiple control points on the original spline; the original spline is segmented according to the multiple control points to obtain multiple spline segments; the normal directions of the multiple control points are obtained and stored, wherein the normal direction of each control point is the vector direction of the spline segment before each control point, thereby obtaining the normal directions of the multiple control points on the original spline and obtaining multiple spline segments.

[0061] The embodiment of the present application also provides another possible implementation of the spline data processing method by calculating the current angle of the current spline segment. Figure 6 The fourth flow chart of a spline data processing method provided in the embodiment of the present application is as follows: Figure 6 As shown, the current angle of the current spline segment is calculated according to the normal direction of the starting point and the normal direction of the end point of the current spline segment among multiple spline segments, including: S401 : Perform a dot product operation on the normal direction of the starting point and the normal direction of the end point of the current spline segment to obtain a first dot product operation result.

[0062] S402: Perform an inverse trigonometric operation on the result of the first dot product operation to obtain a current angle of the current spline segment.

[0063] In this embodiment, the normal direction of the starting point of the current spline segment is the vector direction last_N of the previous spline segment adjacent to the current spline segment, and the normal direction of the end point of the current spline segment is the vector direction next_N of the current spline segment.

[0064] Then, a dot product operation is performed on the normal direction of the starting point of the current spline segment and the normal direction of the end point to obtain the first dot product operation result. Then, an arccos (inverse cosine trigonometric function) operation is performed on the first dot product operation result to obtain the current angle of the current spline segment, which is recorded as angle.

[0065] It should be noted that if the current spline segment is the first spline segment, the normal direction of the starting point and the normal direction of the end point of the first spline segment are the same, both being the vector direction next_N of the first spline segment, and the angle of the first spline segment is 180 degrees.

[0066] In the method provided in an embodiment of the present application, a first dot product operation result is obtained by performing a dot product operation on the normal direction of the starting point of the current spline segment and the normal direction of the end point; then an inverse trigonometric operation is performed on the first dot product operation result to obtain the current angle of the current spline segment, which is used to adjust the current spline segment according to the current angle.

[0067] The present application embodiment also provides another possible implementation of the spline data processing method. Figure 7 The fifth flow chart of a spline data processing method provided in the embodiment of the present application is as follows: Figure 7 As shown, before determining the target angle corresponding to the current spline segment from the preset target angle array according to the current angle of the current spline segment, the method further includes: S501: Determine whether the angle of the current spline segment meets a preset angle correction condition based on the normal direction of the starting point and the normal direction of the end point of the current spline segment and a preset reference direction.

[0068] S502: If a preset angle correction condition is met, determine the difference between 360 degrees and the current angle of the current spline segment as the corrected angle of the current spline segment.

[0069] In this embodiment, based on the normal direction of the starting point and the normal direction of the end point of the current spline segment and a preset reference direction, it is determined whether the angle of the current spline segment meets the preset angle correction condition, that is, whether the actual angle of the current spline segment is greater than 180 degrees.

[0070] Since inverse trigonometric operations are used in the process of calculating the current angle of the current spline segment, the calculated current angles are all less than 180 degrees, while the actual angle of the current spline segment may be greater than 180 degrees. If, based on the normal direction of the starting point and the normal direction of the end point of the current spline segment, as well as the preset reference direction, it is determined that the actual angle of the current spline segment is greater than 180 degrees, but the calculated current angle of the current spline segment is less than 180 degrees, it is determined that the current angle of the current spline segment meets the preset angle correction condition, and the current angle of the current spline segment needs to be corrected. In this case, the corrected angle of the current spline segment is 360-angle.

[0071] If the actual angle of the current spline segment is less than 180 degrees, it is determined that the current angle of the current spline segment does not meet the preset angle correction condition, and in this case, the current angle of the current spline segment does not need to be corrected.

[0072] In the method provided in an embodiment of the present application, whether the angle of the current spline segment meets a preset angle correction condition is determined based on the normal direction of the starting point and the normal direction of the end point of the current spline segment, as well as a preset reference direction. If the preset angle correction condition is met, the difference between 360 degrees and the current angle of the current spline segment is determined as the corrected angle of the current spline segment, thereby ensuring the accuracy of the current angle of the current spline segment.

[0073] The present application embodiment also provides another possible implementation of the spline data processing method. Figure 8 The sixth flow chart of a spline data processing method provided in the embodiment of the present application is as follows: Figure 8 As shown, according to the normal direction of the starting point and the normal direction of the end point of the current spline segment and the preset reference direction, determining whether the angle of the current spline segment meets the preset angle correction condition includes: S601: Perform a cross product operation on the normal direction of the starting point and the normal direction of the end point of the current spline segment to obtain a cross product operation result.

[0074] S602: Perform a dot product operation on the cross product operation result and a preset reference direction to obtain a second dot product operation result.

[0075] S603: If the result of the second dot product operation is less than 0, determine whether the current angle of the current spline segment meets a preset angle correction condition.

[0076] S604: If the result of the second dot product operation is greater than 0, determine that the current angle of the current spline segment does not meet a preset angle correction condition.

[0077] In this embodiment, the preset reference direction may be the positive Y-axis direction in Houdini software, i.e., {0, 1, 0}, where the axis perpendicular to the default plane in Houdini software is the Y-axis. A cross product operation is then performed on the normal direction of the starting point of the current spline segment and the normal direction of the end point to obtain a cross product result. A dot product operation is then performed on the cross product result and the preset reference direction to obtain a second dot product result. Based on the second dot product result, it is determined whether the actual angle formed by the normal direction of the starting point and the normal direction of the end point is less than 180 degrees or greater than 180 degrees.

[0078] If the result of the second dot product operation is less than 0, it means that the actual angle of the current spline segment is greater than 180 degrees, while the calculated current angle of the current spline segment is less than 180 degrees. Therefore, it is determined that the current angle of the current spline segment meets the preset angle correction condition, and the corrected angle of the current spline segment is 360-current angle.

[0079] If the result of the second dot product operation is greater than 0, it means that the actual angle of the current spline segment is less than 180 degrees, and the calculated current angle of the current spline segment is also less than 180 degrees. Therefore, it is determined that the current angle of the current spline segment does not meet the preset angle correction condition, and the current angle of the current spline segment is not corrected, thereby ensuring the accuracy of the current angle of the current spline segment.

[0080] The embodiment of the present application further provides another possible implementation of a spline data processing method, which adjusts the angle of a current spline segment to a corresponding target angle, including: Adjust the position of the end point of the current spline segment so that the angle of the current spline segment after adjustment is the corresponding target angle.

[0081] In this embodiment, when processing the current spline segment, the angles of the spline segments before the current spline segment have all been processed into standard angles, that is, the angles contained in the target_angles array. In this loop, only the position of the end point of the current spline segment is adjusted so that the angle of the current spline segment after adjustment is the corresponding target angle.

[0082] Based on the above example, the embodiment of the present application also provides another possible implementation of the spline data processing method: Figure 9 The seventh flow chart of a spline data processing method provided in an embodiment of the present application is as follows: Figure 10 A schematic diagram of a target spline provided in an embodiment of the present application, Figure 11 This is a schematic diagram of multiple target splines provided in an embodiment of the present application. Figure 9 As shown, adjust the position of the end point of the current spline segment, including: S701: Determine the angle difference between the target angle corresponding to the current spline segment and the current angle.

[0083] S702: Determine a target rotation parameter at the end point of the current spline segment according to the angle difference.

[0084] S703: Rotate the current spline segment around the starting point according to the target rotation parameter to obtain a target vector.

[0085] S704: Determine the target end point position of the current spline segment according to the target vector, the start point of the current spline segment, and the length of the current spline segment.

[0086] S705: Adjust the end point of the current spline segment to the target end point position.

[0087] In this embodiment, the angle difference delta_degree between the target angle corresponding to the current spline segment and the current angle is calculated, and the target rotation parameter at the end point of the current spline segment is determined based on the angle difference. Then, based on the target rotation parameter, the current spline segment is rotated around the starting point to obtain the target vector.

[0088] Among them, the target rotation parameter determines the direction in which the current spline segment rotates around the starting point. For example, if the angle difference is positive, the target rotation parameter at the end point of the current spline segment is positive, and the current spline segment is rotated right around the starting point by delta_degree to obtain the target vector; if the angle difference is negative, the target rotation parameter at the end point of the current spline segment is negative, and the current spline segment is rotated left around the starting point by delta_degree to obtain the target vector.

[0089] Then, according to the target vector, the starting point of the current spline segment and the length of the current spline segment, the target end point position of the current spline segment is determined. Specifically, the target end point position = the starting point position of the current spline segment + the target vector × the length of the current spline segment, thereby obtaining the target end point position of the current spline segment, and adjusting the end point of the current spline segment to the target end point position to complete the adjustment of the angle of the current spline segment, so that the angle of the current spline segment after adjustment is the corresponding target angle.

[0090] like Figure 10 As shown, the dotted line is the original spline, and the solid line is the spline after all the angles of the spline segments on the original spline are adjusted, i.e., the target spline. It can be seen that the basic trends of the original spline and the target spline are consistent, but the regularized target spline only has the angles in the preset target angle array target_angles.

[0091] If there are multiple original splines in the virtual scene, the above steps are applied to each original spline to obtain the target spline corresponding to each original spline, such as Figure 11 As shown, each target spline only has the angles in the preset target angle array target_angles.
