How do I make a texture which is not rectangular? for example it's a circle or an elipse? how do I specify the coordinate of (s,t) of the texture to be map to a rectangular for example?
Oh ya for more detail.. actualy the texture is rectangle but only part of this texture area I'm interested. This part of texture is in the form of circle or elipse.
