NAME

tex3Dlod - performs a texture lookup with a specified level of detail in a given sampler.

SYNOPSIS

   float4 tex3Dlod(sampler3D samp, float4 s)
   float4 tex3Dlod(sampler3D samp, float4 s, int texelOff)
 
 
 
   int4 tex3Dlod(isampler3D samp, float4 s)
   int4 tex3Dlod(isampler3D samp, float4 s, int texelOff)
 
 
 
   unsigned int4 tex3Dlod(usampler3D samp, float4 s)
   unsgined int4 tex3Dlod(usampler3D 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.
