摘要
粒子运动和变化是三维动画中常见的特效,仅仅通过Maya等三维软件自带的粒子制作系统不能高效、便捷的制作一些特定的粒子特效。文章对物体飘落特效的动画模拟开发设计了一个基于MEL语言的脚本模块,首先通过对物体真实飘落特征的分析将它们分为了小花瓣类、大花瓣类、薄片状、絮状四类物体,根据物体飘落的物理特性进行了受力分析,建立了物体飘落仿真模块开发的计算模型,研究了四类物体的重力因子、阻力、风力、旋转速度等仿真参数。该模块可快速制作物体飘落的动画特效,同时能通过变量参数的修改反复变化动画效果。
Particle motion and change is a common special effect in 3D animation. The particle making system with Maya and other 3D softwares can not make some special effects efficiently and conveniently. In this paper, a script module based on MEL lan-guage is designed for the animation simulation of object falling effects. First of all, through the analysis of the real falling character-istics of objects, they are divided into small petals, large petals, thin flake, and flocculent, and according to the physical characteris-tics of the physical characteristics of physical analysis, the calculation model of object falling simulation module is established, and the simulation parameters such as gravity factor, drag force, wind force and rotation speed of four kinds of objects are studied. This module can quickly produce the object falling animation special effects, and meanwhile repeatedly change the animation effect through the variable parameter modification.
