Public Member Functions

 PolyPrimitive (Type t=TRISTRIP)
 PolyPrimitive (const PolyPrimitive &other)
virtual ~PolyPrimitive ()
Type GetType ()
virtual void AddVertex (const dVertex &Vert)
 Add a new vertex to the primitive.
void Clear ()
 Clears out the primitive.
Primitive Interface
virtual PolyPrimitive * Clone () const
virtual void Render ()
virtual dBoundingBox GetBoundingBox ()
virtual void RecalculateNormals (bool smooth)
 Only makes sense for certain primitive types.
virtual void ApplyTransform (bool ScaleRotOnly=false)
virtual string GetTypeName ()
 This needs to be set appropriately for all derived types.
Topology functions
Functions to get topological information about the primitive. These are lazily computed and stored as they can take some time.

const vector<vector<int> >& Fluxus::PolyPrimitive::GetConnectedVerts (  )  [inline]

Connected verts is a list of lists of vertices which are coincident. If this polyprimitive is indexed the coincident verts are calculated by looking at the index values and the position of the index is stored, otherwise it's done by looking at the actual vertex positions, with a small allowed error, and the index is stored.

Definition at line 71 of file PolyPrimitive.h.

const vector<vector<pair<int,int> > >& Fluxus::PolyPrimitive::GetUniqueEdges (  )  [inline]

Unique edges is a list of coincident edges in the topology, formed by pairs of vert indexes, or index positions if the poly is indexed.
