Inherits Primitive.


Public Member Functions

 Triangle (Material *material, const Point &A, const Point &B, const Point &C)
 Define parameters.
virtual ~Triangle ()
virtual void getBounds (BoundingBox &bbox) const
virtual void intersect (HitRecord &hit, const RenderContext &context, const Ray &ray) const
 Intersect ray with triangle.
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.
