Surface position can be inferred by calculating backward from the
depth buffer. Each pixel on the screen represents a ray from the
camera into the scene, and the depth value in the pixel indicates a
distance along the ray. Because of this, it is not actually necessary
to store surface position explicitly - it is only necessary to store
depth values. Of course, OpenGL does that for free.
So the framebuffer now needs to store surface normal, diffuse color,
and depth value (to infer surface position). In practice, most
ordinary framebuffers can only store color and depth - they don't have
any place to store a third value. So we need to use a special
offscreen buffer with an "auxiliary" bitplane. The auxiliary bitplane
stores the surface normal.
So then, there's the final postprocessing pass. This involves
combining the diffuse color texture, the surface normal texture, the
depth texture, and the light parameters into a final rendered output.
The light parameters are passed into the postprocessing shader as
constants, not as textures.
If there are a lot of lights, things get interesting. You use one
postprocessing pass per light. Each pass only needs to scan those
framebuffer pixels that are actually in range of the light in
question. To traverse only the pixels that are affected by the light,
just render the illuminated area's convex bounding volume.
The shader to store the diffuse color and surface normal is trivial.
But the final postprocessing shader is a little complicated. What
makes it tricky is that it needs to regenerate the original surface
position from the screen position and depth value. The math for that
deserves some explanation.
We need to take a clip-space coordinate and depth-buffer value
(ClipX,ClipY,ClipZ,ClipW) and unproject it back to a view-space
(ViewX,ViewY,ViewZ) coordinate. Lighting is then done in view-space.
Okay, so here's the math. Panda uses the projection matrix to
transform view-space into clip-space. But in practice, the projection
matrix for a perspective camera always contains four nonzero
constants, and they're always in the same place:
-- here are the non-zero elements of the projection matrix --
A 0 0 0
0 0 B 1
0 C 0 0
0 0 D 0
-- precompute these from above projection matrix --
