折痕角

A modifier based on the Crease Angle (angle between two adjacent faces). If a stroke segment does not lie on a crease (i.e. the edge does not have the Crease Angle nature), its properties are not touched by the modifier.

Min Angle and Max Angle

The range of input values to the mapping. Out-of-range crease angle values will be clamped by the Min and Max angles and their corresponding property values.
