DESCRIPTION

RiRayObjectInstance(const RiAffineTMatrix3 &trans, RiRayObject *obj);

Default Constructor

    RiRayObjectInstance(const RiAffineTMatrix3 &trans, RiRayObject *obj);

RiInterval GetMinMax(const RiUnitVector3 &) const;

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

    virtual RiInterval  GetMinMax(const RiUnitVector3 &) const;

bool Shadow(RiRay3 &) const;

Does the ray hit the object. Nothing more.

    virtual bool	Shadow(RiRay3 &) const;

bool Intersect(RiRay3 &, RiRayHit &);

Compute an intersection and return it and any other data in the RiRayHit structure. The T value for the ray is set correctly based on the intersection point.

    virtual bool	Intersect(RiRay3 &, RiRayHit &);

void Accept(RiRayObjectVisitor &visitor);

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

    virtual void	Accept(RiRayObjectVisitor &visitor);

RiLightObject *BuildLightObject(const RiAffineTMatrix3 &mat);

Build a RiLightObject if possible, otherwise return NULL;

    virtual RiLightObject *BuildLightObject(const RiAffineTMatrix3 &mat);

RiReal ConditionalHit() const;

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

    virtual RiReal 	ConditionalHit() const;
