Extracts from the egg subgraph beginning at the indicated node a set of all the texture objects referenced, grouped together by filename. Texture objects that share a common filename (but possibly differ in other properties) are returned together in the same element of the map. Definition at line 45 of file eggUtilities.cxx.

Splits a vertex into two or more vertices, each an exact copy of the original and in the same vertex pool. The splitting is based on some arbitrary property of the primitives that own the vertex. In the extreme, each primitive may get a different copy of the vertex, although it is also possible for some primitives to still share vertices. This decision is made based on the function object 'sequence'. This object must define the following function: int operator () (const EggPrimitive *prim) const; This function returns a sequence number, which determines which primitives will share which vertices. The sequence number 0 refers to the original vertex pointer; other sequence numbers indicate new vertices. Other than that, the sequence number is totally arbitrary. Primitives for which the sequence number is the same will end up sharing the same copy of the vertex. Definition at line 82 of file eggUtilities.I.
