This class provides a polygon in 3D space, based on the triangulation of a surface. It may be the approximate representation of a curve on the surface, or more generally the shape. A PolygonOnTriangulation is defined by a table of nodes. Each node is an index in the table of nodes specific to a triangulation, and represents a point on the surface. If the polygon is closed, the index of the point of closure is repeated at the end of the table of nodes. If the polygon is an approximate representation of a curve on a surface, you can associate with each of its nodes the value of the parameter of the corresponding point on the curve.represents a 3d Polygon.

Detailed Description
This class provides a polygon in 3D space, based on the triangulation of a surface. It may be the approximate representation of a curve on the surface, or more generally the shape. A PolygonOnTriangulation is defined by a table of nodes. Each node is an index in the table of nodes specific to a triangulation, and represents a point on the surface. If the polygon is closed, the index of the point of closure is repeated at the end of the table of nodes. If the polygon is an approximate representation of a curve on a surface, you can associate with each of its nodes the value of the parameter of the corresponding point on the curve.represents a 3d Polygon.
Constructor & Destructor Documentation
| Poly_PolygonOnTriangulation::Poly_PolygonOnTriangulation | ( | const TColStd_Array1OfInteger & | Nodes | ) |
Constructs a 3D polygon on the triangulation of a shape, defined by the table of nodes, <Nodes>.
| Poly_PolygonOnTriangulation::Poly_PolygonOnTriangulation | ( | const TColStd_Array1OfInteger & | Nodes, |
| const TColStd_Array1OfReal & | Parameters | ||
| ) |
Constructs a 3D polygon on the triangulation of a shape, defined by:
- the table of nodes, Nodes, and the table of parameters, <Parameters>. where:
- a node value is an index in the table of nodes specific to an existing triangulation of a shape
- and a parameter value is the value of the parameter of the corresponding point on the curve approximated by the constructed polygon. Warning The tables Nodes and Parameters must be the same size. This property is not checked at construction time.
