reads an mpoly from the indicated file pointer.

Documentation

reads an mpoly from the indicated file pointer. The format for the file is:

• 1 float for density; units assumed kg/m^3
• 3 floats for R, G, B, each from 0 to 1
• 1 int for number of vertices
• list of vertices, with x, y, and z for each vertex
• 1 int for the number of faces nfaces
• a list of nfaces polyhedron faces. For each face:
  • 1 int for the number of points in the face npts
  • a list of npts ints specifying the indices of the points in the list of vertices. The points should be in counter-clockwise order, when viewed from outside the polyhedron.

A file describing a red cube with density 1000 kg/m^2, with 1m edges and centered at (0.5, 0.5, 0.5) would look like this:
