gmEdge* gmEdge::getNext (   )  const [inline]

get the next for the edge the edge that is next in the "ring" in clockwise order Note: edge edge MUST half a next.. otherwise the mesh is invaid/non manifold example: if "this" is edge A then getNext() returns a pointer to edge B example: if "this" is edge D then getNext() returns a pointer to edge E See also: setNext() getOpposite() setOpposite() Returns: returns a pointer to the next edge Reimplemented from NhalfEdge. Reimplemented in ParticleEdge. Definition at line 88 of file gmMesh.h. References NhalfEdge::getNext(). Referenced by ModButterflySubdivision::divideEdge(), and ModButterflySubdivision::subdivide().

gmEdge* gmEdge::getOpposite (   )  const [inline]

get the opposite for the edge Note: every edge has at most one opposite. hence this structure does not support non-manifold meshes. example: if "this" is edge C then getOpposite() returns a pointer to edge D example: if "this" is edge A then getOpposite() returns NULL See also: getNext() setNext() setOpposite() Returns: returns a pointer to the Opposite edge Reimplemented from NhalfEdge. Reimplemented in ParticleEdge. Definition at line 87 of file gmMesh.h. References NhalfEdge::getOpposite(). Referenced by ModButterflySubdivision::divideEdge(), and ModButterflySubdivision::subdivide().

gmEdge* gmEdge::getPrevious (   )  const [inline]

get the previous for the edge the edge that is previous in the "ring" in clockwise order slow.. method traverses ring to get edge... Note: edge edge MUST half a previous.. otherwise the mesh is invaid/non manifold. each edge does not explicity store a pointer to its previous.. it only knows what its next is. Hence get previous is implemented by performing a series of getNext() operations, traversing around the ring of half edges example: if "this" is edge A then getNext() returns a pointer to edge C example: if "this" is edge D then getNext() returns a pointer to edge F See also: setNext() getNext() Returns: returns a pointer to the previoius edge if complete ring of clockwise edges exist Reimplemented from NhalfEdge. Reimplemented in ParticleEdge. Definition at line 89 of file gmMesh.h. References NhalfEdge::getPrevious(). Referenced by ModButterflySubdivision::divideEdge().

gmVertex* gmEdge::getVertexA (   )  const [inline]

get the "from" vertex of the edge Note: every edge must be connected to two vertices.. a "from" vertex (e.g. vertexA) and a "to" vertex (e.g. vertexB ) example: if "this" is edge A then getVertexA() returns a pointer to vertex 3 See also: getVertexB(); Returns: returns vertex that the edge is leaving from Reimplemented from NhalfEdge. Reimplemented in ParticleEdge. Definition at line 85 of file gmMesh.h. References NhalfEdge::getVertexA(). Referenced by ModButterflySubdivision::divideEdge().

gmVertex* gmEdge::getVertexB (   )  const [inline]

get the "to" vertex of the edge Note: every edge must be connected to two vertices.. a "from" vertex (e.g. vertexA) and a "to" vertex (e.g. vertexB ) example: if "this" is edge A then getVertexB() returns a pointer to vertex 1 See also: getVertexA(); Returns: returns vertex that the edge is going to Reimplemented from NhalfEdge. Reimplemented in ParticleEdge. Definition at line 86 of file gmMesh.h. References NhalfEdge::getVertexB(). Referenced by ModButterflySubdivision::divideEdge().
