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 ( )

inline

Constructs a triangle and sets all indices to zero.

Poly_Triangle() [2/2]

Poly_Triangle::Poly_Triangle ( const Standard_Integer  theN1, const Standard_Integer  theN2, const Standard_Integer  theN3  )

inline
