   float4 tex2Dcmpbias(sampler2D samp, float4 s, int texelOff)

PARAMETERS


samp
Sampler to lookup.
s
Coordinates to perform the lookup. The value used in the shadow comparison should be passed right after the normal coordinates. 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 shadow compare and bias in sampler samp using coordinates s.

PROFILE SUPPORT

tex2Dcmpbias is supported in fragment profiles starting with fp40 and in vertex profiles starting with vp40. Variants with texelOff are only supported in gp4 and newer profiles.
