如何模拟具有动态性、不规则性和随机性的自然雪景是当前虚拟现实领域研究的热点,采用位移映射构造近处多边形构造的雪块的方法,采用3ds Max创建雪景模型,导入OpenGL中加纹理映射,结合VC++2010的程序编写,以较小的系统资源消耗达到了更加实时逼真的效果,实现了整片雪花飘荡效果和虚拟雪景的真实模拟,为相关领域的动画模拟研究提供了新的思路.
How to simulate the dynamic,irregular and random natural snow is a hot field of virtual reality research.The method of displacement mapping is used to structure polygon blocks of snow nearby.3ds Max is used to create snow models that are imported into OpenGL.Texture mapping is then added.Combined with VC + + 2010 programs,a realistic simulation of snow drift effect is brought out.Less system resources are consumed to achieve more realistic snowscape effect in real time.A new way of thinking for the related fields of animation simulation study is pointed out.
