I heard that there are some plotting errors in new python versions and conda enviroments. I admitedly have no idea where this comes from or how to solve it!

Thank you very much for your reply, I will test other demos first.

FYI. In my environment,

3.8.10	3.3.4	OK	OK
3.9.12	3.4.3	OK	OK
3.10.4	3.5.1	NG	--

So it does not build in 3.10? I heard somewhere that the way setuptools work changed at some point recently, so maybe thats the case.

I assume the Arrow3D has to do with matlplotlib.

In any case, PR #370 changes this demo for something quite nicer, however it needs some work to make it compatible with general TIGRE usage (i.e. not conda, and posibility of running it on a cluster, i.e. change the visual backed, as it does now). See discussion on #357.

I simply don't have time to test and work on that PR.

I was able to solve it by putting below function in Arrow3D class in the plot_geometry.py.

  def do_3d_projection(self, renderer=None):
        from mpl_toolkits.mplot3d import proj3d
        xs3d, ys3d, zs3d = self._verts3d
        xs, ys, zs = proj3d.proj_transform(xs3d, ys3d, zs3d, self.axes.M)
        self.set_positions((xs[0], ys[0]), (xs[1], ys[1]))
        return np.min(zs)

@harshitAgr Do you want to make a pull request to add this to the repo?

[harshitAgr]

sure, just sent it PR# 377
