NAME

tex1Dbias - performs a texture lookup with bias in a given sampler.

SYNOPSIS

   float4 tex1Dbias(sampler1D samp, float4 s)
   float4 tex1Dbias(sampler1D samp, float4 s, int texelOff)
 
 
 

   int4 tex1Dbias(isampler1D samp, float4 s)
   int4 tex1Dbias(isampler1D samp, float4 s, int texelOff)
 
 
 

   unsigned int4 tex1Dbias(usampler1D samp, float4 s)
   unsigned int4 tex1Dbias(usampler1D samp, float4 s, int 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

tex1Dbias 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.
