Poly_Triangle Class Reference

Describes a component triangle of a triangulation (Poly_Triangulation object). A Triangle is defined by a triplet of nodes within [1, Poly_Triangulation::NbNodes()] range. 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 within [1, Poly_Triangulation::NbNodes()] range. 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() [1/2]

Poly_Triangle::Poly_Triangle ( )
