   bool allowOutside,
   out Point2D proj,
   out Vector2D W
)

Parameters

P

The 3D point to project

coincTol

Relevant only when P lays on the surface. When the distance between P and its projection is smaller then this value, the projection is considered succesful.

allowOutside

When true, the projection is not constrained inside the surface domain

proj

The parametric coordinates of projection on surface to P

W

The 2D tangent vector in parametric space
