A method and system for generating a motion model trajectory

Abstract

The invention discloses a method and system for generating a trajectory of a motion model, which specifically includes: importing a motion model and a static model of the earth into a simulation space, and generating the landform contour map according to the undulating surface of the model; selecting trajectory points Generate a Bezier curve; obtain the latitude and longitude information corresponding to the control points of the Bezier curve and the discrete points in the static model of the earth; obtain the geographic height corresponding to the surface according to the contour map; according to the geographic height and flight The height of the object from the ground obtains the spatial height information of the control point and the discrete point; the spatial parameters of the control point and the discrete point are obtained in combination with the latitude and longitude information; The surface of the earth model quickly generates a motion model trajectory that is closer to the real world, which improves the drawing efficiency, makes the animation effect closer to the real world, and makes the modification operation more convenient.

Description

technical field [0001] The invention relates to the field of digital graphics and animation production, in particular to a method and system for generating motion model tracks. Background technique [0002] With the rapid development of digital animation and its wide application in the field of video production, in some TV program productions that need to complete demonstrations through animation, there are often movements of flying objects flying at low altitudes on the earth, such as helicopters to observe the ground situation airplane. [0003] However, in the process of making specific flying object trajectories, making the flight trajectories of low-altitude flying objects is a very complicated task, especially on the model surface with complex landforms, which requires a lot of work from the staff. Not only that, but the effect is also similar to that of The reality is quite different. [0004] In the prior art, the method commonly used in geographic information prod...

AI Technical Summary

Problems solved by technology

[0005] (1) The effect of flying is achieved by changing the spatial position of the flying object on the key frame. If the terrain is relatively complex, the workload will be very large, time-consuming and inefficient;

[0006] (2) Similarly, it is difficult to make a realistic animation effect of undulating mountains on the surface of complex terrain only by adding key frames;

[0007] (3) When the terrain changes, it is difficult to modify the trajectory of the motion model made by using the existing technology, and there is no reuse value
