Public Member Functions | |
| virtual | ~Shape () |
| Release all memory. | |
| virtual void | addChild (NoriObject *child) override |
| Add a child object to the current instance. More... | |
| virtual void | activate () override |
| Initialize internal data structures (called once by the XML parser) | |
| const BoundingBox3f & | getBoundingBox () const |
| bool | isEmitter () const |
| Is this mesh an area emitter? | |
| Emitter * | getEmitter () |
| Return a pointer to an attached area emitter instance. | |
| const Emitter * | getEmitter () const |
| Return a pointer to an attached area emitter instance (const version) | |
| const BSDF * | getBSDF () const |
| Return a pointer to the BSDF associated with this mesh. | |
| virtual uint32_t | getPrimitiveCount () const |
| Return the total number of primitives in this shape. | |
| virtual BoundingBox3f | getBoundingBox (uint32_t index) const =0 |

| virtual void | sampleSurface (ShapeQueryRecord &sRec, const Point2f &sample) const =0 |
| Sample a point on the surface (potentially using the point sRec.ref to importance sample) This method should set sRec.p, sRec.n and sRec.pdf Probability should be with respect to area. | |
| virtual float | pdfSurface (const ShapeQueryRecord &sRec) const =0 |
| Return the probability of sampling a point sRec.p by the sampleSurface() method (sRec.ref should be set before) sRec.n and sRec.pdf are ignored. | |
| virtual EClassType | getClassType () const override |
| Return the type of object (i.e. Mesh/BSDF/etc.) provided by this instance. | |
