the first approach to dealing with this is to perturb the depth being output from the pixel shader by a depth stored in the particle texture.
解决这个问题的第一个办法是是改变深度。这个深度由像素着色器根据储存在粒子纹理中的深度生成。
the scene in this sample is rendered using a pixel shader to control the ambient, diffuse, and specular contribution of each light at every pixel.
该例子的场景渲染使用了像素着色器来控制环境光,漫反射,镜面反射作用于每个像素上的各个光照。
the really cool thing about pixel shader effects is that you can use adobes pixel bender tool to create custom pixel shader effects and use them in your flex application.
