Constructor & Destructor Documentation G3D::MeshAlg::Face::Face (  )  Member Function Documentation bool G3D::MeshAlg::Face::containsDirectedEdge ( int  e  )  const [inline] Contains the forward edge e if e >= 0 and the backward edge ~e otherwise. bool G3D::MeshAlg::Face::containsEdge ( int  e  )  const [inline] bool G3D::MeshAlg::Face::containsVertex ( int  v  )  const [inline] Member Data Documentation int G3D::MeshAlg::Face::edgeIndex[3] Edge indices in counter-clockwise order. Edges are undirected, so it is important to know which way each edge is pointing in a face. This is encoded using negative indices. If edgeIndex[i] >= 0 then this face contains the directed edge between vertex indices edgeArray[face.edgeIndex[i]].vertexIndex[0] and edgeArray[face.edgeIndex[i]].vertexIndex[1]. If edgeIndex[i] < 0 then ~edgeIndex[i] (i.e. the two's complement of) is used and this face contains the directed edge between vertex indices edgeArray[~face.edgeIndex[i]].vertexIndex[0] and edgeArray[~face.edgeIndex[i]].vertexIndex[1]. Degenerate faces may include the same edge multiple times. const int G3D::MeshAlg::Face::NONE [static] Used by Edge::faceIndex to indicate a missing face. This is a large negative value. int G3D::MeshAlg::Face::vertexIndex[3] Vertices in the face in counter-clockwise order. Degenerate faces may include the same vertex multiple times.
