DESCRIPTION

RiParametricRadObject();

Default Constructor

    RiParametricRadObject();

RiParametricRadObject(RiParametricSurface *surf, RiParametricMesh *mesh);

 Constructs from basic elements

    RiParametricRadObject(RiParametricSurface *surf, RiParametricMesh *mesh);

~RiParametricRadObject();

 Destructor

    virtual ~RiParametricRadObject();

RiReal GetSample(RiRadRegion &sample, const RiVector2 &uv);

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

    virtual RiReal       GetSample(RiRadRegion &sample, const RiVector2 &uv);

RiRadData *GetRadData();

 Get the Rad Data from the object

    virtual RiRadData   *GetRadData();

RiConvexHull GetConvexHull();

 Get a convex hull containing 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);

int GetNumChildren();

 Determine the number of children this object has. (0 if no subdivision has been done 

    virtual int		 GetNumChildren();

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();

RiReal GetArea();

 Compute the surface area (or a good estimate of it) of the object

    virtual RiReal	 GetArea();
