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:

  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.
