火焰动画快速模拟的新方法

针对火焰动画难以快速建模和绘制的问题,提出了完全利用GPU过程化生成火焰动画的高效算法。先用建模工具在预处理阶段构建一个由平面正方形组成的三维模型,在绘制阶段通过GPU编程对这些方形进行Billboard方式的变换,并用一些简单公式对他们的运动方式、大小和颜色来用过程化方式进行控制,最后通过alpha混合得到最终结果。算法完全在GPU里实现,能满足实时的绘制要求。

A new method for fast simulation of fire animation

Aiming at fast modeling and rendering of flame animation, the authors present in this paper an algorithm that is able to generate fire animation efficiently by taking advantage of GPU. They first construct a model from a series of planar squares in the pre-processing stage with modeling tools, in the rendering stage, transform these squares in the way of Billboard, then control their movement, size and color with some simple formulas, and finally obtain the desired result by alpha blending. The algorithm is implemented entirely in the GPU and it meets the real-time rendering requirements.
