Sorry for the confusing error message here, you may need to downgrade taichi_three to v0.0.3 by executing:

python3 -m pip install taichi_three==0.0.3

Oh I see, does https://github.com/archibate/taichi/blob/upgrade-ms-cloth-005/examples/mass_spring_3d.py with pip install taichi_three==0.0.5 work?

Actually our GUI don't support fullscreen at this moment.. Use an external GUI package for display like PyOpenGL if you need that, and interface with Taichi using pixels.to_numpy().
