Example:

This example shows how to print out the point positions and the triangle data for a polygon mesh.

        using namespace XSI;
        using namespace MATH;

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

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

        Geometry geom(myCube.GetActivePrimitive().GetGeometry());
        CPointRefArray points(geom.GetPoints());
        CVector3Array positions( geom.GetPoints().GetPositionArray() );

        LONG ulCount = positions.GetCount();
        app.LogMessage( L"Object: " + myCube.GetName() );
        app.LogMessage( L"Points: " + CValue((LONG)ulCount).GetAsText() );

        // Print out the x,y,z positions of each point
        for (LONG i=0; i<ulCount; ++i )
        {
            app.LogMessage(
                CValue(positions[i].GetX()).GetAsText() + L"," +
                CValue(positions[i].GetY()).GetAsText() + L"," +
                CValue(positions[i].GetZ()).GetAsText() );
        }

        // Print out the point indices for each triangle
        CTriangleRefArray triangles(geom.GetTriangles());
        CLongArray indices( triangles.GetIndexArray() );

        app.LogMessage( L"Triangles: " + CValue(triangles.GetCount()).GetAsText());

        ulCount = indices.GetCount();
        for (i=0; i<ulCount; i += 3 )
        {
            app.LogMessage( CValue(indices[i]).GetAsText() + L"," +
                CValue(indices[i+1]).GetAsText() + L"," +
                CValue(indices[i+2]).GetAsText() );
        }

Constructor & Destructor Documentation

Default destructor.

Constructor.

Parameters:

in_ref

constant reference object.

Copy constructor.

Parameters:

in_obj

constant class object.

Member Function Documentation

Returns the type of the API class.

Returns:

The class type.

Reimplemented from SIObject.

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 Triangle object.

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 Triangle object.

Reimplemented from SIObject.

Returns an array of neighbor Triangle objects for this triangle. The array may contain empty objects whose represent the unexisting neighbour triangles.

Returns:

Array of neighbor Triangle objects.

Returns an array of TriangleVertex objects for this triangle.

Returns:

Array of TriangleVertex objects.

Returns the index of this Triangle object in its geometry.

Returns:

The Triangle index.

Returns the index of the polygon from which this Triangle comes.

Returns:

The Polygon index.

Returns an array of CVector3 objects representing the position of all TriangleVertex objects of this Triangle object.

Returns:

Array of CVector3 objects.

Returns the TriangleVertex normals for this Triangle as an array of CVector3 objects. Triangle objects that belong to the same polygon will have the same normal values.

Returns:

Array of CVector3 objects.

Returns the TriangleVertex colors for this Triangle as an array of VertexColor objects.
