Public Member Functions
	Plane ()
	Creates a plane primitive.
	Plane (float u, float v, Material *m=0)
	Creates a plane primitive of size u x v, with material m.
virtual	~Plane ()
	Destroys the plane.
void	setSize (float u, float v)
	Sets the size of the plane.
bool	intersect (const Ray &ray) const
	Returns true if the ray intersects the plane.
bool	intersect (const Ray &ray, Intersection &isect) const
	Returns true if the ray intersects the sphere.
void	setMaterial (Material *m)
	Sets the material of the primitive to the material pointed to by m, or if m is 0, the material is set to the default material (diffuse gray).
Material *	getMaterial () const
	Returns a pointer to the primitive's material.
void	setTransform (Matrix &M)
	Manually set the local transform matrix to M.
void	setTranslation (const Vector &T)
	Sets the translation of the node to T.
void	setTranslation (float tx, float ty, float tz)
	Sets the translation of the node to (tx,ty,tz).
void	setScale (float s)
	Sets the scale uniformly to s.
void	setScale (const Vector &S)
	Sets the scale non-uniformly to S.
void	setScale (float sx, float sy, float sz)
	Sets the scale non-uniformly to (sx,sy,sz).
void	setRotation (const Vector &R)
	Sets the rotation about the x,y,z axes to the components of R.
void	setRotation (float rx, float ry, float rz)
	Sets the rotation about the x,y,z axes to (rx,ry,rz) respectively.
Protected Types
