Poly_Triangle Class Reference

Describes a component triangle of a triangulation (Poly_Triangulation object). A Triangle is defined by a triplet of nodes. Each node is an index in the table of nodes specific to an existing triangulation of a shape, and represents a point on the surface. More...

Detailed Description

Describes a component triangle of a triangulation (Poly_Triangulation object). A Triangle is defined by a triplet of nodes. Each node is an index in the table of nodes specific to an existing triangulation of a shape, and represents a point on the surface.

Constructor & Destructor Documentation

Poly_Triangle::Poly_Triangle

(

)

Constructs a triangle and sets all indices to zero.

Poly_Triangle::Poly_Triangle	(	const Standard_Integer	N1,
