Public Member Functions
	Mesh ()
	Creates a mesh primitive.
	Mesh (const std::string &filename, Material *m=0)
	Loads a mesh from the specified file.
virtual	~Mesh ()
	Destroys the mesh.
void	load (const std::string &filename)
	Loads a mesh from the specified file.
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

Protected Member Functions
void	prepare ()
	Prepares the mesh for rendering by transforming all vertex positions/normals to world space.
void	clear ()
	Clears all data associated with the mesh.
void	loadOBJ (const std::string &filename)
	Loads a mesh file in the OBJ format.
void	getGeometry (std::vector< Intersectable * > &geometry)
	Extract all intersectable geometry from the mesh, i.e.
void	addChild (Node *child)
	Adds a node to the list of children.
bool	hasChild (const Node *child) const
	Returns true if a specific node is a child of this node.
