2010-10-13Switch from MultiDrawElements to the extra-vert-at-the-end stips hack.HEADmasterEric Anholt2-59/+39
2010-07-31Skip multiplying the unused column of modelviewEric Anholt1-2/+3
2010-07-13Replace a divide by sqrt with multiply by invsersesqrt.Eric Anholt1-2/+2
2010-07-02Require GLSL 1.20 in the shaders.Eric Anholt4-0/+8
I rely on implicit conversions of types a lot, and 1.20 is basically everywhere.
2010-05-25Add support for EXT_timer_query.Eric Anholt1-3/+75
2009-11-09Update for GLU3 API changes.Eric Anholt2-14/+15
2009-09-09draw/readbuffer state is part of the fbo, so no need to reset it per frame.Eric Anholt1-4/+2
2009-08-11Move a bunch of division for the ward calc out to uniforms.Eric Anholt4-8/+19
2009-08-10Disable the conditional brdf calc as a hack.Eric Anholt1-0/+6
2009-08-10Move the rings drawing code to a separate file.Eric Anholt4-497/+552
2009-08-07Shuffle BRDF code around to allow avoiding computation in shadowed case.Eric Anholt1-50/+64
This hurts 965, but only because of the brw_wm_glsl failboat.
2009-08-07Clean up n_dot_l and n_dot_v < 0 clamping.Eric Anholt1-4/+1
This is actually a significant performance improvement, by reducing extra comparisons and multiplies.

2009-07-31Update light eye position for the ground shader.Eric Anholt3-2/+4
2009-07-31Fix the light position to be outside of the bounds of the shadow casters.Eric Anholt2-1/+13
