Member Data Documentation

std::vector<int> ACG::SceneGraph::ACG::MeshCompiler::VertexSplitter::splits

split list format: for each vertex: [next split, attribute ids] next split: -1 -> not split yet i -> index into split list for next combination with the same vertex position id (single linked list)

attribute ids: array of attribute indices into input buffers, that makes up the complete vertex -1 -> vertex not used yet (relevant for split() only)
