From 29e013e58be93aa6ed760393cf77ef34ca1d57c0 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 23 Nov 2010 15:55:59 -0800 Subject: mesa: Add gl_MESAFogParamsOptimized for our special pre-computed fog params. It would be nice if we handled optimized uniform math like this in some generic way, since people often end up doing uniform expressions in shaders, but for now keep this hard-coded like it was in the texenvprogram code. --- src/mesa/main/uniforms.c | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'src/mesa/main') diff --git a/src/mesa/main/uniforms.c b/src/mesa/main/uniforms.c index c31c07517f0..1d74efafdf7 100644 --- a/src/mesa/main/uniforms.c +++ b/src/mesa/main/uniforms.c @@ -217,6 +217,10 @@ static struct gl_builtin_uniform_element gl_MESABumpRotMatrix1_elements[] = { {NULL, {STATE_INTERNAL, STATE_ROT_MATRIX_1}, SWIZZLE_XYZW}, }; +static struct gl_builtin_uniform_element gl_MESAFogParamsOptimized_elements[] = { + {NULL, {STATE_INTERNAL, STATE_FOG_PARAMS_OPTIMIZED}, SWIZZLE_XYZW}, +}; + #define MATRIX(name, statevar, modifier) \ static struct gl_builtin_uniform_element name ## _elements[] = { \ { NULL, { statevar, 0, 0, 0, modifier}, SWIZZLE_XYZW }, \ @@ -322,6 +326,7 @@ const struct gl_builtin_uniform_desc _mesa_builtin_uniform_desc[] = { STATEVAR(gl_MESABumpRotMatrix0), STATEVAR(gl_MESABumpRotMatrix1), + STATEVAR(gl_MESAFogParamsOptimized), {NULL, NULL, 0} }; -- cgit v1.2.3
