Look for ShadowVolumes.txt
I already wrote something even better to limit volume extrusion to the radius of the light source, but I'm running into a special case where the shadows go flashing like crazy even though I'm checking thouroughly for when it's safe to cap/uncap the volume.
I think I figured a workaround for it which involves casting a ray from the light source passing by the center of the occluder and checking for intersection with the near clip plane delimited by the viewport corners, and deciding to force cap in the case of an intersection.

Don't use this one yet, I modified few other things in the scenegraph that I should upload sometime soon (back to school, I'm overwhelmed...)
Code:
!!ARBvp1.0

PARAM mvp[4]	    = { state.matrix.mvp };
PARAM lightPosition = program.env[0];

PARAM zero = {0.0, 0.0, 0.0, 0.0};
PARAM one  = {1.0, 1.0, 1.0, 1.0};

ATTRIB inPosition = vertex.position;
ATTRIB inNormal   = vertex.normal;

TEMP lightVector, dotProduct;
TEMP multiplier, position;
TEMP toMult;

SUB lightVector.xyz, inPosition, lightPosition;
DP3 dotProduct,  lightVector, inNormal;

MOV multiplier, lightPosition.w;

MOV toMult, one;
SGE toMult, dotProduct, zero;

MUL multiplier, multiplier, toMult;

MAD position, multiplier, lightVector, inPosition;

DP4 result.position.x, mvp[0], position;
DP4 result.position.y, mvp[1], position;
DP4 result.position.z, mvp[2], position;
DP4 result.position.w, mvp[3], position;
MOV result.color, vertex.color;
END

Abba Zabba, sorry, I didn't look the program carefully. I thought you're doing extrusion in GPU and finding Silhouette with CPU. Now I see you're doing both with CPU.

Total number of frames: 2054.
Minimum number of frames: 47.9588.
Maximum number of frames: 101.713.
Average number of frames: 93.3327.

Just did this quick run with a moded 5950u bios set at 300/510/970 !

However not anywhere near the quality of display shown at first post. Mine has BLUE elephant and pillers. Is this what should happen with a FX5900 card ????

EDIT:

And this run with my usual moded 5950u bios set at 300/530/970,

Benchmark duration: 22.0038(s).
Total number of frames: 2102.
Minimum number of frames: 49.7856.
Maximum number of frames: 104.154.
Average number of frames: 95.5289.

Obviously the frame count has gone up, but are there norms for different graphics cards to use as a ref of performance ??
