解决全局照明问题的一种可能方法是使用粒子模型,其中粒子在要渲染的场景中执行随机漫游。该算法使用该粒子模型,但以直接方式计算像素的照度。为了优化采样过程,采用了自适应概率密度函数。其结果是,粒子被射入那些具有高潜在能力的区域。该算法具有一些优点,例如不需要网格,并且可以使用相同的方法处理所有类型的灯光-曲面交互。
One possible method for solving the global illumination problem is to use a particle model, where particles perform a random walk through the scene to be rendered. The proposed algorithm uses this particle model, but computes the illumination of the pixels in a direct manner. In order to optimise the sampling process, adaptive probability density functions are used. The result is that particles are shot to those regions with a high potential capability. This algorithm has some advantages, such as the absence of a mesh and the possibility to handle all types of light-surface interactions with the same method.
