I truly thought that I was responding to this question in the "hijacked" thread (see the mesh examples in matplotlib gallery):
I have code which generates a mesh, i.e., as a N x 3 array of doubles V of the 3D points and another M x 3 array of integers F of the triangles. How can I render this mesh via qt3d (note the mesh is generated and hence not loaded from a file)? As far as I understand I need to create my own QGeometryRenderer, QGeometry, QBuffer, QAttribute.
So .. pros and cons of Qt3D vs. matplotlib? Where is this discussed?
