from_pydata(vertices, edges, faces)

Make a mesh from a list of vertices/edges/faces Until we have a nicer way to make geometry, use this.

Parameters:
  • vertices (iterable object) – float triplets each representing (X, Y, Z) eg: [(0.0, 1.0, 0.5), ...].
  • edges (iterable object) – int pairs, each pair contains two indices to the vertices argument. eg: [(1, 2), ...]
  • faces (iterable object) – iterator of faces, each faces contains three or four indices to the vertices argument. eg: [(5, 6, 8, 9), (1, 2, 3), ...]
