I want to plot a tetrahedron mesh by matplotlib
, and the following are a simple tetrahedron mesh:
xyz = np.array([[-1,-1,-1],[ 1,-1,-1], [ 1, 1,-1],[-1, 1,-1],[-1,-1, 1],[ 1,-1, 1], [ 1, 1, 1],[-1, 1, 1]], dtype=np.float) tets = np.array([[0,1,2,6],[0,5,1,6],[0,4,5,6],[0,7,4,6],[0,3,7,6],[0,2,3,6]], dtype=np.int)
Of course, in practical applications, the number of tetrahedrons in a mesh can be large. I can't find any useful help information in google. So what is the better way to plot a tetrahedron mesh by matplotlib
?
Furthermore, I can get all the triangle faces of the mesh.
tri = np.array([[0, 2, 1],[0, 1, 5],[0, 6, 1],[0, 3, 2],[0, 2, 6],[0, 6, 3],[0, 7, 3],[0, 5, 4],[0, 6, 4],[0, 4, 7],[0, 6, 5],[0, 6, 7],[1, 2, 6],[5, 1, 6],[2, 3, 6],[3, 7, 6],[4, 5, 6],[7, 4, 6]], dtype=np.int)
