Movement locus simulation method and device

Abstract

Embodiments of the invention provide a movement locus simulation method and device. The method comprises the following steps: providing a movement locus setting parameter setting interface; acquiring movement locus setting parameters of movement elements through the movement locus setting parameter setting interface; determining position information of each key points on movement loci of the movement elements by using a preset curve formula and the movement locus setting parameters; converting the position information of each key point into position information of movement loci in a plurality of animation frames; and generating movement locus simulation data according to the position information of movement elements in each animation frame, wherein the movement locus simulation data is used for representing the movement loci of the movement elements which move on the basis of the movement locus setting parameters. In the embodiments, the movement loci of the movement elements are determined by using the preset curve formula and the movement locus setting parameters, so as to ensure that the movement loci accord with the objective laws; therefore, the problem that the simulated movement loci do not accord with the objective laws as the key points are determined manually is solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a motion trajectory simulation method and device. Background technique [0002] In many scenarios, such as animation production scenes such as web design and game screens, it is necessary to design the animation effect of oblique or flat throwing motion for motion elements (oblique or flat throwing motion can be collectively referred to as uniform speed curve motion). [0003] In the existing design method, when designing the dynamic effect of uniform speed curve motion, the design figure 1 Take the dynamic effect of kicking football as an example, the designer will subjectively judge the trajectory of the moving element (that is, the football), manually determine each key point (sampling point) on the trajectory, and then measure the coordinate position of the key point. For example figure 1 The coordinate point in (x 0 ,y 0 ) to (x 6 ,y 6 ) are the coordinate positions ...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned design method has the following disadvantages, which are relatively subjective: because the key points need to be manually determined, the characterization of the dynamic effect varies from person to person, and the simulated trajectory of the moving object may not conform to the objective laws (physical principles)
