Class Description

An array of cluster elements in a Cluster object.

A cluster maps the geometry component (Point, Segment, Facet, Sample point) indices to cluster element indices. The value of the element in a cluster element array is the geometry component's index.

A cluster element array is read-only.

Warning:

This specialized array is returned by Cluster::GetElements, 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 XSI;
                Application app;
                Model root = app.GetActiveSceneRoot();

                X3DObject myGrid;
                root.AddGeometry( L"Grid", L"MeshSurface", L"", myGrid );

                CLongArray indices(9);
                indices[0] = 8; indices[1] = 16; indices[2] = 24; indices[3] = 32;
                indices[4] = 40; indices[5] = 48; indices[6] = 56; indices[7] = 64;
                indices[8] = 72;

                Cluster myCls;
                myGrid.GetActivePrimitive().GetGeometry().AddCluster(siVertexCluster, L"",
                        indices, myCls );

                CClusterElementArray elements(myCls.GetElements());

                CLongArray values(elements.GetArray());

                for (LONG i=0; i<values.GetCount(); ++i)
                {
                        app.LogMessage(L"Element " + CValue(i).GetAsText() + L"= " +
                                CValue(values[i]).GetAsText());
                }
