Therefore, the actual execution order may change according to the actual situation.

[0034] The implementation details of the technical solutions of the embodiments of the present disclosure will be elaborated in detail below.

[0035] Figure 1 Schematically shows a flowchart of a trajectory rendering method in an exemplary embodiment of the present disclosure. As Figure 1 shown, the trajectory rendering method includes steps S101 to S103:

[0036] Step S101, loading a basic spline trajectory;

[0037] Step S102, obtaining trajectory editing information for the basic spline trajectory; wherein, the trajectory editing information includes any one or more of scaling information, rotation information, and vibration information;

[0038] Step S103, adjusting the basic spline trajectory according to the trajectory editing information to obtain a target trajectory, and rendering the target trajectory.

[0039] In the technical solutions provided by some embodiments of the present disclosure, on the basis of the basic spline trajectory, it is supported to edit the trajectory by scaling, rotating, and vibrating. On the one hand, it can solve the problems of non-visualization and difficult derivative calculation when using mathematical formulas to calculate the trajectory, and reduce the complexity of trajectory rendering; on the other hand, the increase of editing rules can also improve the diversity and rationality of the ballistic trajectory, avoid the uniformity of the trajectory, and enhance the user's gaming experience.

[0040] Next, each step of the trajectory rendering method in this exemplary embodiment will be described in more detail with reference to the accompanying drawings and embodiments.

[0041] In step S101, a basic spline trajectory is loaded.

[0042] In an embodiment of the present disclosure, in the development of some game projects, skills with ballistic effects can be implemented, and it is necessary to render the ballistic trajectory in a game engine (in this disclosure, UE4, that is, Unreal Engine 4, is taken as an example for illustration) to bring a better gaming experience to users.

[0043] Figure 2 Schematically shows a diagram of a basic spline trajectory in an exemplary embodiment of the present disclosure. As Figure 2As shown, the style of the basic spline trajectory loaded in UE4 is displayed, which includes multiple control points 201-204, shown as small square blocks. Among them, the left control point 201 is the starting point of the spline, and the right control point 204 is the ending point of the spline. When finally rendering the trajectory, the style of the ballistic trajectory flows from the starting point to the ending point.

[0044] In step S102, trajectory editing information for the basic spline trajectory is obtained; wherein, the trajectory editing information includes any one or more of scaling information, rotation information, and vibration information.

[0045] In an embodiment of the present disclosure, the trajectory rendering method provided by the present disclosure supports three editing information, including scaling, rotation, and vibration.

[0046] For scaling adjustment, it mainly includes two types: Smiliar approximate scaling and Stretch stretching scaling. Among them, Smiliar approximate scaling scales the scaling control points as a whole on the x, y, and z axes in three-dimensional space, while Stretch stretching scaling keeps the distance on one axis (usually the z axis, representing height) of the scaling control points unchanged and scales on the other two axes.

[0047] When the trajectory editing information is scaling information, the user needs to configure the scaling type, scaling ratio, and scaling control points during trajectory editing. The scaling type can determine the scaling method, whether to use approximate scaling or stretching scaling; the scaling ratio is used to calculate the position information of the control points after adjustment and the spline trajectory. A positive ratio value means magnification, and a negative ratio value means reduction; the scaling control points determine the spline trajectory to be scaled. It is possible to scale only the local trajectory corresponding to a part of the control points in the spline or scale the entire spline. Usually, the scaling control points can be configured by default as all the control points on the entire spline to scale the entire spline trajectory as a whole.

[0048] For rotation adjustment, the trajectory formed by the control points to be rotated is rotated as a whole according to the rotation angle and rotation direction.

[0049] When the trajectory editing information is rotation information, the user needs to configure the rotation angle, rotation direction, and rotation control points during trajectory editing to rotate the trajectory corresponding to the rotation control points by a certain angle in accordance with the rotation direction. For the rotation control points, similar to the scaling adjustment, during the rotation adjustment, it is also possible to rotate the entire spline or a part of the spline, or the rotation control points can be default set to all the control points of the spline.

[0050] In an embodiment of the present disclosure, the method further includes: configuring the rotation angle, and the configuring the rotation angle includes: configuring a minimum random rotation angle and a maximum random rotation angle to obtain a random rotation angle range; and randomly setting based on the random rotation angle range to determine the rotation angle.

[0051] Specifically, the rotation angle can be randomly generated by the system. The user can set the Min Roll Range, that is, the minimum random rotation angle, and the Max Roll Range, that is, the maximum random rotation angle, to obtain a random rotation angle range. Then, when rotating, a rotation angle can be randomly set from the random rotation angle range to rotate the control point.

[0052] In an embodiment of the present disclosure, the user can also set an angle as the rotation angle.

[0053] It should be noted that the rotation direction can also be determined by distinguishing the rotation angle as positive or negative. For example, if the rotation angle is positive, it is clockwise rotation; if the rotation angle is negative, it is counterclockwise rotation. Of course, the rotation angle and the rotation direction can also be set separately.

[0054] For vibration adjustment, the control point to be vibrated is offset according to the vibration intensity configured by the user, the vibration direction, and the calculated offset amount.

[0055] When the trajectory editing information is vibration information, the user needs to configure the vibration intensity, the vibration direction, and the vibration control points during trajectory editing. The greater the vibration intensity value, the greater the displacement offset of the control point; the vibration direction affects the offset direction of the control point; for the vibration control points, during vibration adjustment, it can be a single control point adjustment, or it can be a vibration adjustment for a partial spline line or the entire spline line composed of multiple control points. Additionally, the vibration control points can also be default set to all the control points of the spline line.

[0056] In an embodiment of the present disclosure, the vibration direction can be randomly set using a random vibration direction function. Specifically, for example, in the UE4 Unreal Engine for game development, the vibration direction is obtained in the way of FRotator(FMath::RandRange(-180,180),FMath::RandRange(-180,180),0).Vector(). Of course, the user can also configure a direction value as the vibration direction for vibration adjustment.

[0057] In the actual spline line editing process, these three editing methods can be flexibly applied and combined. For example, only rotation adjustment can be performed, or the three methods can be mixed and superimposed.

[0058] In step S103, the target trajectory is obtained by adjusting the basic spline trajectory according to the trajectory editing information, and the target trajectory is rendered.

[0059] In an embodiment of the present disclosure, the process of the scaling adjustment method is as follows: the scaling type and the scaling ratio are extracted according to the scaling information, and the scaling control points in the basic spline trajectory are determined; wherein, the scaling type includes approximate scaling or stretch scaling; based on the scaling type and the scaling ratio, the spline information after scaling adjustment is calculated as the target trajectory.

[0060] Specifically, when the scaling type is approximate scaling, the position information of the scaling control points on the first coordinate axis, the second coordinate axis, and the third coordinate axis and the spline trajectory are calculated based on the scaling ratio; or when the scaling type is stretch scaling, the position information of the scaling control points on the first coordinate axis and the second coordinate axis and the spline trajectory are calculated based on the scaling ratio.

[0061] Figure 3 Schematically shows a schematic diagram of a spline before scaling in an exemplary embodiment of the present disclosure. Refer to Figure 3 As shown, there are two control points 301 and 302 to be scaled, and the spline corresponding to the control points. Next, Smiliar approximate scaling and Stretch stretch scaling are respectively used to perform scaling adjustment on it.

[0062] Figure 4 Schematically shows a schematic diagram of a spline after approximate scaling in an exemplary embodiment of the present disclosure, that is, the control points will be scaled as a whole on the x, y, and z axes in the three-dimensional space to obtain 401 and 402, and the spline as a whole has changes.

[0063] Figure 5 Schematically shows a schematic diagram of a spline after stretch scaling in an exemplary embodiment of the present disclosure. Stretch stretch scaling can keep the distance between the control points unchanged in height, and finally obtain the control points 501 and 502, and the spline trajectory.

[0064] In an embodiment of the present disclosure, the process of the rotation adjustment method is as follows: the rotation angle and the rotation direction are extracted according to the rotation information, and the rotation control points in the basic spline trajectory are determined; based on the rotation angle and the rotation direction, the spline information after rotation adjustment is calculated as the target trajectory.

[0065] Specifically, the spline corresponding to the rotation control point is rotated by a certain angle according to the rotation direction to obtain the position information of the control point.

[0066] In an embodiment of the present disclosure, the process of the vibration adjustment method is as follows: extracting the vibration intensity and vibration direction according to the vibration information, and determining the vibration control points in the basic spline trajectory; calculating the spline information after vibration adjustment based on the vibration intensity and the vibration direction as the target trajectory.

[0067] Specifically, first, it is necessary to determine the vibration intensity Distrotion and the vibration direction VDir according to the vibration information. Then, based on the vibration intensity and the vibration direction, calculate the position information of the vibration control points after vibration adjustment, which specifically includes the following steps: for a vibration control point, determine the minimum distance value of the vibration control point based on the first distance and the second distance between the vibration control point and the adjacent two vibration control points; calculate the vibration value according to the minimum distance value and the vibration intensity, and calculate the vibration offset of the vibration control point according to the vibration value and the vibration direction; determine the position information of the vibration control point after vibration adjustment based on the vibration offset.

[0068] During vibration adjustment, vibration adjustment can be performed only on one vibration control point, or on multiple vibration control points in the spline. Only when adjusting multiple vibration control points, it is also necessary to traverse each single vibration control point one by one to determine the final trajectory style.

[0069] Taking the vibration adjustment of the entire spline as an example, starting from the second control point at the starting point of the spline to the penultimate control point, traverse the control points one by one; calculate the distance L1 between the control point and the previous control point and the distance L2 between the control point and the next control point respectively; obtain the minimum distance value through L1 and L2, denoted as Length; calculate the vibration value VDelta according to the minimum distance value Length × vibration intensity Distrotion; then calculate the vibration offset PosDelta through the vibration value VDelta × vibration direction VDir; finally, add the original value of the control point and the vibration offset PosDelta to obtain the position information of the control point, and at the same time, smoothly connect each control point to obtain the style after vibration adjustment.

[0070] Figure 6 Schematically shows a schematic diagram of a spline after vibration adjustment in an exemplary embodiment of the present disclosure. Refer to Figure 2 As shown, it is the spline style before adjustment. When vibrating the 201 control point, the spline style shown in Figure 6 is obtained.

[0071] In an embodiment of the present disclosure, it is also possible to perform adjustment of the Applied To Root modification point, that is, modify the control point to the target position.

[0072] Based on the above method, the ballistic trajectory can be edited using splines in a visual way; meanwhile, scaling, rotation, and vibration can be performed during runtime, thus obtaining diverse and reasonable ballistic trajectories.
