Edge Class Reference

Detailed Description

The Edge object gives access to the geometry edges of an X3DObject's primitive.

Edges are the PolygonMesh-specifics of Segments. You can reach edges from PolygonFace::GetEdges and PolygonMesh::GetEdges.

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

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

        PolygonMesh mesh( myCube.GetActivePrimitive().GetGeometry() );

        Edge edge( mesh.GetEdges().GetItem(0) );
        app.LogMessage( L"This object is an: " + edge.GetClassIDName() );

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

Reimplemented from Segment.

siClassID GetClassID ( ) const [virtual]

Returns the type of the API class.

Returns:
The class type.

Reimplemented from Segment.

Edge& operator= ( const Edge 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_objconstant class object.
Returns:
The new Edge object.
Edge& 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_refconstant class object.
Returns:
The new Edge object.

Reimplemented from Segment.

CVertexRefArray GetVertices ( ) const

Returns the vertices at the ends of this edge.

Returns:
An array of Vertex objects
CPolygonNodeRefArray GetNodes ( ) const

Returns the PolygonNode objects adjacent to this edge.

Returns:
An 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 2 Vertex objects comprising the current Edge are returned.

Parameters:
in_lDistanceValue Represents the degree of neighborhood (eg., degree=2 for an edge means its adjacent vertices plus the adjacent vertices of the adjacent vertices).
Returns:
An 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 the Edge objects are returned in counter-clockwise order.

Parameters:
in_lDistanceValue Represents the degree of neighborhood (eg., degree=2 for an edge means its adjacent vertices plus the adjacent vertices of the adjacent vertices).
Returns:
An 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 the adjacent PolygonFace objects are returned (1 if border edge, 2 otherwise).

Parameters:
in_lDistanceValue representing the degree of neighborhood (eg., degree=2 for an edge means its adjacent vertices plus the adjacent vertices of the adjacent vertices).
Returns:
An array of PolygonFace objects
CEdgeRefArray GrowNeighborEdges ( LONG  in_lDistance = 1) const

Returns an array of Edge objects that are adjacent to this Edge object, within a given distance.

Parameters:
in_lDistanceValue representing the degree of neighborhood (eg., degree=2 for an edge means its adjacent vertices plus the adjacent vertices of the adjacent vertices).
Returns:
An array of Edge objects
double GetCrease ( ) const

Returns:
The crease value between 0.0 and 10.0.
Since:
3.5.1
bool GetIsHard ( ) const

Returns whether the edge is hard or not.

Returns:
True if the edge is hard, false if not.
Since:
3.5.1
bool GetIsBoundary ( ) const

Returns whether the edge is a boundary or not.

Returns:
True if the edge is a boundary, false if not.
Since:
4.2
