Control (UI) Default Value Function
shadingInterpolation constant Controls how values are interpolated across a micropolygon.
If constant, the color and opacity of all the pixels inside the
micropolygon are the same. If smooth, the colors and
opacities are interpolated from the calculated values.
Note that this must be set to smooth for use with C.entered
Derivatives and Normals.
Note also that shading interpolation is really an attribute, not
an option, so it can be set on a per-object basis.
shadingRate 1 Sets the frequency of shading, in pixel area per shade. For
example, 1.0 means at least once per pixel; .25 means
approximately 4 times per pixel. 4.0 would mean
micropolygons could be 2x2 pixels or so in size.
