positiveEdgeInset
The distance from each positive edge (+X, +Y, +Z) of the clip bounds over which opacity fades to 0, expressed in local coordinate space units.
Declaration
var positiveEdgeInset: SIMD3<Float>Discussion
Values range from 0.0 to the half-extent of the bounding box on each axis. For example:
0.0means no feathering on that edge.An inset distance value of
2.0on X axis creates a 2-unit feather zone inward from the +X edge.
