Interface FaceClosestPoint (Models.OCCT)

The point of a face nearest a given point: its u and v as fractions of the face's UV bounds, as shapes.face.pointOnUV takes them, its distance from the given point, the face's unit normal there, and whether it lies on the face's boundary, where a point beyond the face's edges comes to.
