Name
texRBUF - performs an unfiltered multisample texture lookup in a given renderbuffer sampler.
Synopsis
float4 texRBUF(samplerBUF samp, int2 c, int s) int4 texRBUF(isamplerBUF samp, int2 c, int s) uint4 texBUF(usamplerRBUF samp, int2 c, int s)Parameters
- samp
- Sampler to lookup.
- c
- Coordinates to perform the lookup.
- s
- sample within a multi-sampled renderbuffer.
Description
Performs an unfiltered multisample texture lookup in renderbuffer sampler samp using coordinates c and sample s.
Renderbuffer samplers are created with the NV_eplicit_multisample extension. See:
http://www.opengl.org/registry/specs/NV/explicit_multisample.txtProfile Support
texRBUF is supported in gp4, gp5, and glsl profiles.
