public class OrderIndpTransparencyEffect extends WildMagic.LibGraphics.Effects.ShaderEffect
This class sets up the final pass in rendering multiple semi-transparent surfaces. Rendering multiple translucent surfaces is accomplished with the following steps: 1. A FrameBuffer Object (FBO) is created with three render-to-texture targets, and a depth buffer. 2. The first render target is activated. Solid objects are rendered: writing color and depth information to the FBO target1. The color information displays the solid objects, the depth information enables the solid objects to properly occlude the translucent objects. 3. The second and third render targets are activated. Translucent objects are rendered: writing accumulated color and alpha to the second target and the number of overlapping surfaces per pixel to the third target. In this pass the depth buffer is read-only. 4. Rendering to the three texture targets is disabled. 5. A screen-space polygon is rendered, it reads the three textures generated in the previous pass. The first texture contains the color from the solid objects, the next two textures contain the color information and weighted-average for rendering the translucent textures.
