Method and system for generating satellite animation

Abstract

The invention discloses a method and a system for generating a satellite animation. Particularly, the method comprises steps of importing an earth model and generating a satellite motion curve in stimulated space; generating discrete points and numbering discrete points in accordance with the satellite motion curve; determining discrete point serial numbers corresponding to current satellite space positions in accordance with current satellite motion schedules; determining satellite directions in accordance with a previous discrete point and a binding discrete point; adding a key frame in an initial state and a key frame in an ending state; interpolating satellite states in all moments into the animation; and generating the animation that a satellite moves round the earth. By the aid of a discrete point binding method, animators cannot sequentially and manually modify satellite space positions at all moments, directions of the satellite in all moments are determined, the motion orbit of the satellite can be controlled at will, the efficiency of the animation production is improved, the effect which is similar to an actual satellite motion effect is achieved, and the animation can be used repeatedly.

Description

technical field [0001] The invention relates to the field of animation effect production, in particular to a satellite animation generation method and system. Background technique [0002] In some demonstrative TV program productions, motions of satellites orbiting the earth are required, such as demonstration animations of weather satellites, manned spaceships or communication satellites. In the process of the actual satellite flying around the earth, just like the moon, one side always faces the earth. For example, the side where the lens of the meteorological satellite takes the satellite cloud image will always face the earth, and the satellite will always move towards the earth. direction. However, in the specific satellite animation production process, it is difficult to draw realistic satellite animation renderings. [0003] In the prior art, the geographical information production system generally modifies the spatial position of the satellite on the key frame to a...

AI Technical Summary

Problems solved by technology

[0004] (1) Modifying the satellite spatial position by changing the key frame is heavy, time-consuming and inefficient;

[0005] (2) If the orientation of the satellite is manually modified, the realistic effect will not be achieved in the end;

[0006] (3) When different satellite motion trajectories are required, the animation made by using the existing technology is difficult to modify and has no reuse value
