Destructor

    virtual ~RiParametricSquareMesh();

Get the root of a predefined mesh (these can be shared) The aspect ratio may be used in the future to provide roots for long thin objects.

    static RiParametricSquareMesh *GetRoot(RiReal uSize = 1.0, RiReal vSize = 1.0);

Convert the (0,1)^2 sampleUV into a uv on the element

    virtual RiVector2 GetSample(const RiVector2 &sampleUV);

Get the number of corners on this element

    virtual int	      GetNumCorners();

Get a specific corner

    virtual RiVector2 GetCorner(int i);

Get the area of the element (in 0,1 land)

    virtual RiReal    GetArea();

Get the number of children this element has.

    virtual int	      GetNumChildren();

Get a specific child

    virtual RiParametricMesh  *GetChild(int i);

Subdivide the mesh.

    virtual bool      Subdivide();

Is the uv coordinate inside this parametric region

    virtual bool      Inside(const RiVector2 &uv) const;
