NAME

texRECTbias - performs a texture lookup with bias in a given sampler.

SYNOPSIS

   float4 texRECTbias(samplerRECT samp, float4 s)
   float4 texRECTbias(samplerRECT samp, float4 s, int2 texelOff)
 
 
 

   int4 texRECTbias(isamplerRECT samp, float4 s)
   int4 texRECTbias(isamplerRECT samp, float4 s, int2 texelOff)
 
 
 

   unsigned int4 texRECTbias(usamplerRECT samp, float4 s)
   unsigned int4 texRECTbias(usamplerRECT samp, float4 s, int2 texelOff)

PARAMETERS


samp
Sampler to lookup.
s
Coordinates to perform the lookup. The bias value 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 bias in sampler samp using coordinates s.

PROFILE SUPPORT

texRECTbias is supported in fragment profiles starting with fp30 and in vertex profiles starting with vp40. Variants with texelOff are only supported in gp4 and newer profiles. Variants with integer samplers are also only suppported in gp4 and newer profiles.
