4.2 Trait Modifiers

As mentioned earlier there are several traits that can be modified for textures. In their descriptions, T refers to some other texture type that is to be amended by the modifier.

ShBorderClamp<T>:
Clamp texture lookups with extreme texture coordinates to a border value
ShEdgeClamp<T>:
Clamp texture lookups with extreme texture coordinates to the edge of the texture (default)
ShWrapRepeat<T>:
Repeat the texture for texture lookups outside its range
/ E  ShInterpolate<N, T>:
Set the degree of interpolation to N Useful values for this are 0 for nearest-neighbour lookups, 1 for linear interpolation, and 3 for cubic (Catmull-Rom) interpolation. A value of 2 will be upgraded to 3, anything higher than 3 will be reduced to 3.
/ E  ShMIPFilter<T>:
Use MIP-mapped filtering (turn it on if it is off).
/ E  ShNoMIPFilter<T>:
Do not use MIP-mapped filtering (turn it off if it is on).
