RiParametricSurface

Mapping from R2 to R3

This is an abstract class and cannot be directly instanced.

	// Members

Destructor

    virtual ~RiParametricSurface()  ;
;

Function is currently defined inline.

Get all interpolated data

    virtual void GetSurfaceData(RiVector3 &point, RiUnitVector3 &normal, RiReal &jacobian,
				RiVector2 &newUV, const RiVector2 &uv);

Get an R3 point from and R2 point

    virtual RiVector3 GetPoint(const RiVector2 &uv);

Get the Jacobian (area multiplier) at a point

    virtual RiReal GetJacobian(const RiVector2 &uv);

Can a specified region on the surface see the hull?

    virtual bool   IsVisible(const RiParametricMesh &mesh, const RiConvexHull &hull) const;

Inverse of GetSurfaceData function

    virtual RiVector2 GetInverseUV(const RiMaterialRegion &sample) const;
