Description:
|
Sense is a relative direction associated with some entity, with respect to some associated entity. If the directions are the same, the sense is said to be
forward. If the directions are opposite, the sense is said to be
reversed. Sense applies to face normals and their underlying surface normals, coedges and their underlying edges, edges and their underlying curves, etc.
|
|
|
For example, the normal to a face can be either the same direction as the normal of the underlying surface at any position, or it can be the reverse of the surface normal. If it is the same as the surface normal, the face's sense relative to the surface normal is forward; otherwise, its sense is reversed.
