Inherits Object.

Inherited by Box, Cyl, Plane, Ring, Sphere, and Triangle.


Public Member Functions

 Primitive (Material *matl)
 Constructor needs material.
virtual ~Primitive ()
virtual void preprocess ()
 This is called before rendering to allow the primitive to pre-compute terms.
virtual void intersect (HitRecord &hit, const RenderContext &context, const Ray &ray) const =0
 Intersect ray with primitive.
virtual void normal (Vector &normal, const RenderContext &context, const Point &hitpos, const Ray &ray, const HitRecord &hit) const =0
 Return normal for the hit location. Generally called after all ray-geometry intersection to get the normal for the hit point.
virtual void computeUVW (Vector &uvw, const RenderContext &context, const Ray &ray, const HitRecord &hit) const
 Get UVW coordinates for hit location.
