◆ getPixel()

virtual void PtexReader::ConstantFace::getPixel ( int  u,
int  v,
void *  result 
)
inlinevirtual

Read a single texel from the data block.

The texel coordinates, u and v, have a range of [0..ures-1, 0..vres-1]. Note: this method will work correctly even if the face is constant or tiled.

Reimplemented from PtexReader::PackedFace.
