Detailed Description

Adjacency information for a vertex.

Does not contain the vertex position or normal, which are stored in the MeshAlg::Geometry object. Vertexs must be stored in an array parallel to (indexed in the same way as) MeshAlg::Geometry::vertexArray.

Member Data Documentation

edgeIndex

SmallArray<int, 6> G3D::MeshAlg::Vertex::edgeIndex

Array of edges adjacent to this vertex.

Let e = edgeIndex[i].
edge[(e >= 0) ? e : ~e].vertexIndex[0] == this vertex index.

Edges may be listed multiple times if they are degenerate.

faceIndex

SmallArray<int, 6> G3D::MeshAlg::Vertex::faceIndex

Array of faces containing this vertex.

Faces may be listed multiple times if they are degenerate.
