   float4 texRECTlod(samplerRECT samp, float4 s, int texelOff)
 
 
 

   int4 texRECTlod(isamplerRECT samp, float4 s)
   int4 texRECTlod(isamplerRECT samp, float4 s, int texelOff)
 
 
 

   unsigned int4 texRECTlod(usamplerRECT samp, float4 s)
   unsigned int4 texRECTlod(usamplerRECT samp, float4 s, int texelOff)

PARAMETERS


samp
Sampler to lookup.
s
Coordinates to perform the lookup. The level of detail should be passed as the last component of the coordinate vector.
texelOff
Offset to be added to obtain the final texel.

DESCRIPTION

Performs a texture lookup with a specified level of detail in sampler samp using coordinates s.
