.Ip "samp" 8
.IX Item "samp"
Sampler to lookup.
.Ip "s" 8
.IX Item "s"
Coordinates to perform the lookup. The value used in the projection should be passed as the last 
component of the coordinate vector. 
.Ip "texelOff" 8
.IX Item "texelOff"
Offset to be added to obtain the final texel.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Performs a texture lookup in sampler \fIsamp\fR using coordinates \fIs\fR, the coordinates used in the 
lookup are first projected, that is, divided by the last component of the coordinate vector and
them used in the lookup. 
.SH "PROFILE SUPPORT"
.IX Header "PROFILE SUPPORT"
\&\fBtexCUBEproj\fR is supported in all fragment profiles and all vertex profiles starting with 
vp40. Variants with integer samplers are only supported in gp4 and 
newer profiles.
