Integer Portion of Texture Coordinates
What about (s,t) outside of range (0,1)?
- In OpenGL texture coordinates > 1 can be used to cause texture to repeat on the surface
- Can control whether texture appears just once, wraps in the s direction, or wraps in the t direction or both.
Integer portion of (s,t) does not affect the (s,t) conversion to (u,v) at the pixel level.
