Using texture boundary modes

• When texture coordinates extend past the edge of the image they can:

• Wrap to create a repeating pattern (as before with the scaling transform)

• Or Clamp to prevent repeatition

• When clamped, parts of the cookie outside the image are filled with a boundary color (with an interpolation with the boundary of the texture)

• Methods on Texture select WRAP or CLAMP boundary modes in S and T, and the color

• WRAP is the default in both S and T
