Class Description

An array of PolygonNode objects representing the edge junction in a polygon.

Warning:

This specialized array is returned by Vertex::GetNodes, PolygonMesh::GetNodes, PolygonFace::GetNodes, and Edge::GetNodes, it is not meant to be created and modified in user-defined functions. If you want to add and remove arbitrary items to a collection, you must use a CRefArray instead.

Example:

                using namespace XSI;
                using namespace MATH;

                Application app;
                Model root = app.GetActiveSceneRoot();

                X3DObject myCone;
                root.AddGeometry( L"Cone", L"MeshSurface", L"", myCone );

                PolygonMesh mesh( myCone.GetActivePrimitive().GetGeometry(0) );
                CPolygonNodeRefArray pnodes(mesh.GetNodes());

                LONG lCount = pnodes.GetCount();
                app.LogMessage( CString(L"Number of nodes: ") + CValue(lCount).GetAsText() );

                CVector3 norm;
                PolygonNode pnode;
                for ( LONG i=0; i<lCount; i++ )
                {
                        bool bValid;
                        pnode = pnodes[i];
                        norm = pnode.GetNormal(bValid);

                        app.LogMessage(
                                L"Normal: (" + CString(CValue(bValid).GetAsText()) +
                                L") " +
                                CValue(norm.GetX()).GetAsText() + L"," +
                                CValue(norm.GetY()).GetAsText() + L"," +
                                CValue(norm.GetZ()).GetAsText() );
                }
