Visualization bug in transformation demo

[zhanghua7099]

Hi!

Thanks for your good course and code.

Currently, I found that the transformation demo (transformation.py) may have a bug. Directly run it can not visualize the 3D result. It will output a blank picture.

For me, I add the following code:

fig.add_axes(ax)

after

3dgs_render_python/transformation.py

Line 94 in 24e9225

ax = Axes3D(fig)

It runs well. Hope this is helpful.
