Default Constructor

    RiTriangle(const RiVector3 &p0, const RiVector3 &p1, const RiVector3 &p2);

General interface for acceleration querries such as bounding boxes and spheres.

    virtual RiInterval  GetMinMax(const RiUnitVector3 &) const;

Does the ray hit the object. Nothing more.

    virtual bool	Shadow(RiRay3 &) const;

Compute an intersection and return it and any other data in the RiRayHit structure.

    virtual bool	Intersect(RiRay3 &, RiRayHit &);

Creates a new light for this object

    virtual RiLightObject  *BuildLightObject(const RiAffineTMatrix3 &mat);

Estimated probability of hitting a primitive given that a ray hits this object's bounding box.

    virtual RiReal 	ConditionalHit() const;

Set the vertex normals

    void SetNormals(const RiUnitVector3 &n0, const RiUnitVector3 &n1, const RiUnitVector3 &n2);

Set the vertex uvs

    void SetUVs(const RiVector2 &uv0, const RiVector2 &uv1, const RiVector2 &uv2);

Set up data in the hit structure

    void UpdateHitAndRay(RiRay3 &ray, RiRayHit &hit, RiReal t, RiReal u, RiReal v);

Accept a visitor to perform (structure preserving) actions on the hierarchy

    virtual void	  Accept(RiRayObjectVisitor &visitor);

Set the material for the RiPolygon

    void SetMaterial(RiMaterial *);

Get the material for the RiPolygon

    RiMaterial *GetMaterial();
