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.

DEFINE_STANDARD_ALLOC | Poly_Triangle () |
Constructs a triangle and sets all indices to zero. | |
Poly_Triangle (const Standard_Integer N1, const Standard_Integer N2, const Standard_Integer N3) | |
Constructs a triangle and sets its three indices to N1, N2 and N3 respectively, where these node values are indices in the table of nodes specific to an existing triangulation of a shape. | |
void | Set (const Standard_Integer N1, const Standard_Integer N2, const Standard_Integer N3) |
Sets the value of the three nodes of this triangle to N1, N2 and N3 respectively. | |
void | Set (const Standard_Integer Index, const Standard_Integer Node) |
Sets the value of the Indexth node of this triangle to Node. Raises OutOfRange if Index is not in 1,2,3 | |
void | Get (Standard_Integer &N1, Standard_Integer &N2, Standard_Integer &N3) const |
Returns the node indices of this triangle in N1, N2 and N3. | |
Standard_Integer | Value (const Standard_Integer Index) const |
Get the node of given Index. Raises OutOfRange from Standard if Index is not in 1,2,3 | |
Standard_Integer | operator() (const Standard_Integer Index) const |
Standard_Integer & | ChangeValue (const Standard_Integer Index) |
Get the node of given Index. Raises OutOfRange if Index is not in 1,2,3 | |
