Looking for a simple example of a viewer with flags, e.g. 'wireframe'

I’m a Python beginner and I run into problems understanding deep nestled import tree in trimesh. I’m trying to add some flags to the basic show() call. I would like to have wireframe, axis, etc., but I’m stuck at not finding proper names for classes and functions, e.g. trimesh.viewer.windowed.SceneViewer. This code snippet:

import trimesh, pyglet

mesh = trimesh.creation.cylinder(1, height=1)
scene = trimesh.Scene([mesh])
viewer = trimesh.viewer.windowed.SceneViewer(scene, flags='wireframe')
viewer.show()

fails with:

  File "/home/paul/upwork/pick/code/test-trimesh.py", line 5, in <module>
    viewer = trimesh.viewer.windowed.SceneViewer(scene, flags='wireframe')
AttributeError: module 'trimesh' has no attribute 'viewer'

How do I import trimesh.viewer.windowed.SceneViewer? Are there any examples? Is there an axis display flag?

Hey, the easiest way to do that is probably to pass the kwargs to the mesh.show or scene.show call, as the kwargs to those calls get passed through to SceneViewer.__init__:

In [1]: import trimesh

In [2]: from trimesh.viewer.windowed import SceneViewer

In [3]: m = trimesh.creation.box()

In [4]: m
Out[4]: <trimesh.Trimesh(vertices.shape=(8, 3), faces.shape=(12, 3))>

In [5]: m.show(flags={'wireframe': True})
Out[5]: SceneViewer(width=1800, height=1350)

In [6]: s = trimesh.Scene([m])

In [7]: s.show(flags={'wireframe': True})
Out[7]: SceneViewer(width=1800, height=1350)

Thanks, it works. I found that show(flags={'wireframe': True, 'axis': True}) works too. I can’t find it in the documentation, though.
