DESCRIPTION

RiPlanarParametricRadObject();

Default Constructor

    RiPlanarParametricRadObject();

RiPlanarParametricRadObject(RiParametricSurface surf, RiParametricMesh mesh);

Constructs from basic elements

    RiPlanarParametricRadObject(RiParametricSurface *surf, RiParametricMesh *mesh);

RiConvexHull GetConvexHull();

Fills in the data in sample, and returns the Area Weight for the sample (area of the object.

    virtual RiConvexHull GetConvexHull();

bool IsVisible(const RiConvexHull &hull);

Can the object see the convex hull. Note that this operation ONLY involves the object and the hull, not the environment. This is the equivalent of back face culling.

    virtual bool	 IsVisible(const RiConvexHull &hull);

void ComputeTransfer(const RiMaterialRegion &sample, RiTransferData &data);

Compute transfer data for links and lighting

    virtual void	 ComputeTransfer(const RiMaterialRegion &sample, RiTransferData &data);

RiRadObject *GetChild(int i);

Get the ith child (i MUST be less than GetNumChildren)

    virtual RiRadObject *GetChild(int i);

bool Subdivide();

Subdivide if possible. If already subdivided, do nothing. Return true if subdividable.

    virtual bool	 Subdivide();

RiRadObject *GetRadObject(const RiMaterialRegion &sample);

Find the leaf associated with this sample

    virtual RiRadObject *GetRadObject(const RiMaterialRegion &sample);
