Dear all,
as a quick inspection of simulation results I would like to add a Python
function that takes a VTK file (3D tetrahedral grid with cell data) and
opens a mayavi window with an interactive slicer. Is that technically
possible and could you point me in the right direction? For the time
being my code only visualizes the gridpoints:
def showMesh3D(mesh, interactive=True):
"""
Proof of concept for mayavi binding.
"""
# should avoid opening of mayavi window when building documentation
if not interactive:
mlab.options.offscreen = True
fig = mlab.figure(bgcolor=(1, 1, 1), size=(400, 400))
# temporary VTK write & read, may be replaced with direct VTK
object.
tmp = "/tmp/3d_view_%s.vtk" % os.getpid()
mesh.exportVTK(tmp)
src = mlab.pipeline.open(tmp, figure=fig)
os.remove(tmp)
surf = mlab.pipeline.surface(src, figure=fig, opacity=0.5)
edges = mlab.pipeline.extract_edges(surf, figure=fig)
mlab.pipeline.surface(edges, color=(0, 0, 0), figure=fig)
#mlab.pipeline.image_plane_widget(surf, colormap='gray',
#plane_orientation='x_axes')
Thanks a lot,
Florian
