NAME

texBUF - performs an unfiltered texture lookup in a given texture buffer sampler.

SYNOPSIS

   float4 texBUF(samplerBUF samp, int s)
 
 
 
   int4 texBUF(isamplerBUF samp, int s)
 
 
 
   unsigned int4 texBUF(usamplerBUF samp, int s)
 
 
 

PARAMETERS


samp
Sampler to lookup.
s
Coordinates to perform the lookup.

DESCRIPTION

Performs an unfiltered texture lookup in texture buffer sampler samp using coordinates s.

Texture buffer samplers are created with the EXT_texture_buffer_object extension. See:

   http://developer.download.nvidia.com/opengl/specs/GL_EXT_texture_buffer_object.txt
 
 
 
Texture buffer object samplers roughly correspond to the tbuffer functionality of DirectX 10.

PROFILE SUPPORT

texBUF is supported in gp4vp, gp4gp, and gp4fp profiles.
