Vertex Class Reference

## Detailed Description

The Vertex object gives access to the geometry vertices of an X3DObject's Primitive. A Vertex is the object PolygonMesh specifics of the Point object.

You can access vertices from Edge::GetVertices, PolygonFace::GetVertices and PolygonMesh::GetVertices.

Example:

            using namespace XSI;
            using namespace MATH;
            Application app;
            Model root = app.GetActiveSceneRoot();

            X3DObject myCube;
            root.AddGeometry( L"Cube", L"MeshSurface", L"", myCube );

            PolygonMesh mesh(myCube.GetActivePrimitive().GetGeometry());
            Vertex vertex0(mesh.GetVertices().GetItem(0));

            app.LogMessage( L"Number of nodes for Vertex 0: " +
                CValue(vertex0.GetNodes().GetCount()).GetAsText() );

## Member Function Documentation

bool IsA | ( | siClassID | in_ClassID | ) | const`[virtual]`

Returns true if a given class type is compatible with this API class.

Parameters:

  in_ClassID | class type.

Returns:
  true if the class is compatible, false otherwise.

Reimplemented from Point.

siClassID GetClassID | ( |  | ) | const`[virtual]`

Returns the type of the API class.

Returns:
  The class type.

Reimplemented from Point.

Vertex& operator= | ( | const Vertex & | in_obj | ) |

Creates an object from another object. The newly created object is set to empty if the input object is not compatible.

Parameters:

  in_obj | constant class object.

Returns:
  The new Vertex object.

Vertex& operator= | ( | const CRef & | in_ref | ) |

Creates an object from a reference object. The newly created object is set to empty if the input reference object is not compatible.

Parameters:

  in_ref | constant class object.

Returns:
  The new Vertex object.

Reimplemented from Point.

CPolygonNodeRefArray GetNodes | ( |  | ) | const

Returns the PolygonNode objects adjacent to this Vertex.

Returns:
  Array of PolygonNode objects.

CVertexRefArray GetNeighborVertices | ( | LONG | in_lDistance = `1` | ) | const

Returns an array of Vertex neighbors within a given distance. If the distance is 1 the Vertex are returned in counter-clockwise order.

Parameters:

  in_lDistance | Value representing the degree of neighborhood

Returns:
  Array of Vertex objects.

CEdgeRefArray GetNeighborEdges | ( | LONG | in_lDistance = `1` | ) | const

Returns an array of Edge neighbors within a given distance.If the distance is 1 all Edge objects for which one of the extremities is the current Vertex are returned in counter-clockwise order.

Parameters:

  in_lDistance | Value representing the degree of neighborhood

Returns:
  Array of Edge objects.

CPolygonFaceRefArray GetNeighborPolygons | ( | LONG | in_lDistance = `1` | ) | const

Returns an array of PolygonFace neighbors within a given distance.If the distance is 1 all PolygonFace for which one of the Vertex objects is the current Vertex are returned in counter-clockwise order.

Parameters:

  in_lDistance | Value representing the degree of neighborhood

Returns:
  Array of PolygonFace objects.

CVertexRefArray GrowNeighborVertices | ( | LONG | in_lDistance = `1` | ) | const

Returns an array of Vertex neighbors adjacent to this Vertex, within a given distance.

Parameters:

  in_lDistance | Value representing the degree of neighborhood

Returns:
  Array of Vertex objects.

double GetCrease | ( |  | ) | const

Returns the crease value associated with this vertex.

Returns:
  The crease value between 0.0 and 10.0.

Since:
  3.5.1

bool GetIsBoundary | ( |  | ) | const

Returns whether the control point is a boundary or not.

Returns:
  true if the control point is a boundary, false if not.

Since:
  4.2
