Dear all, I have a set of points coordinates (x,y,z) representing a surface (in 3D, but it's not a volume). I would like to create a mesh from those points, and then map some values on this mesh (colored surface). Mayavi allows to easily represent the mesh. What I have done so far is: pts=mlab.points3d(x,y,z) delaunay = mlab.pipeline.delaunay3d(pts) surf = mlab.pipeline.surface(delaunay) That's create a nice plot of my mesh, but of course without values mapped on the surface. Beforehand, I have been using mlab.triangular_mesh to create such a colored surface (from a vtk-like file), and would be happy to use the same approach. However, triangular_mesh requires the x,y,z positions, plus a list of triplets defining the connecting triangles. So, my question is: how can I extract those triangles from the delaunay3d object created above? This information is very likely stored somewhere, but after hours of exploration, I haven't been able to extract it!! Thank you in advance for your help !!
