Member Function Documentation

curve_edge_projection_line()

TangentSpace< Geom_traits > ConstructTangentSpace::curve_edge_projection_line	(	Curve_edge	curve_edge,
		std::array< Point_3, 2 >	edge_points ) const

returns a line tangent to the curve to which its edge should align too.

The array contains the two locations of its vertices.

patch_face_projection_plane()

TangentSpace< Geom_traits > ConstructTangentSpace::patch_face_projection_plane	(	Patch_face	patch_face,
		std::vector< Point_3 >	face_points ) const

returns a plane tangent to the patch to which its facet should align too.

The list of Point_3 contains its current vertices location.
