Public Member Functions

 Sphere (Material *material, const Point &center, double radius)
virtual ~Sphere ()
virtual void getBounds (BoundingBox &bbox) const
virtual void intersect (HitRecord &hit, const RenderContext &context, const Ray &ray) const
 Intersect ray with primitive.
virtual void normal (Vector &normal, const RenderContext &context, const Point &hitpos, const Ray &ray, const HitRecord &hit) const
 Return normal for the hit location. Generally called after all ray-geometry intersection to get the normal for the hit point.
