PolygonNode Class Reference

---

Detailed Description

The PolygonNode object gives access to the X3DObject's polygon node geometry. A polygon represents the edge junction of a polygon object.

PolygonFace::GetNodes

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(0) );
        PolygonFace face( mesh.GetPolygons().GetItem(0) );
        PolygonNode node( face.GetNodes().GetItem(0) );

        app.LogMessage( L"Index of Node 0: " +
                        CValue(node.GetIndex()).GetAsText() );

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 Sample.

siClassID GetClassID

(

)

const [virtual]

Returns the type of the API class.

Returns:

The class type.

Reimplemented from Sample.

PolygonNode& operator=

(

const PolygonNode &

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 PolygonNode object.

PolygonNode& 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 PolygonNode object.

Reimplemented from Sample.

LONG GetIndex

(

)

const

Returns the index of this PolygonNode object within the polygon face.

Returns:

The index of this PolygonNode object.

Reimplemented from Sample.

MATH::CVector3 GetNormal

(

bool &

io_bValid

)

const

Returns the normal of this PolygonNode object.

Parameters:

io_bValid

Returns true if the normal is valid.

Returns:

The normal expressed as a CVector3 object..
