From 8fed2466e4056668a76a87cf935b5fbff8ae15ca Mon Sep 17 00:00:00 2001 From: Brian Date: Fri, 26 Oct 2007 19:19:09 -0600 Subject: Re-implement GLSL texture sampler variables. GLSL sampler variables indicate which texture unit to use for TEX instructions. Previously, this was baked into the fragment/vertex program and couldn't be readily changed once set. Now, SamplerUnits[] array indicates which texture unit is to be used for each sampler variable. These values are set with glUniform1i(). This is extra state that must be passed to the fragment/vertex program executor at runtime. --- src/mesa/main/config.h | 1 + 1 file changed, 1 insertion(+) (limited to 'src/mesa/main/config.h') diff --git a/src/mesa/main/config.h b/src/mesa/main/config.h index cebef1c383..8c64248845 100644 --- a/src/mesa/main/config.h +++ b/src/mesa/main/config.h @@ -207,6 +207,7 @@ #define MAX_PROGRAM_ADDRESS_REGS 2 #define MAX_UNIFORMS 128 #define MAX_VARYING 8 +#define MAX_SAMPLERS 8 /*@}*/ /** For GL_ARB_vertex_shader */ -- cgit v1.2.3
