Controls are now thread safe (https://github.com/pygfx/pygfx/pull/55)

Well, first of all, we are quite heavily dependent on numpy, right? So there's that. However, you are right, we don't want to exclude so many users that quickly...

Try `camera.show_object`? Does that do the trick for you? https://github.com/pygfx/pygfx/blob/1b1bf5879b85b2a23aaa1026f44bdbcd812b8c80/pygfx/cameras/_base.py#L41-L59

Ah, I see. Image and Volume don't actually have any geometry (as in, 3d coordinates), so the bounding box is invalid. I'll open a PR to fix that.

That's what camera.show_object does! It takes the worldobject you pass in, retrieves the world space bounding box for the object and all its children, merges them and brings that into...

I fixed the issue, see #303

To be clear, the `camera.show_object` function now supports any object. However, the `Controller` classes don't have a `look_at` or `show_object`-like utility method just yet. That would be the remaining work...

> I think it would make more sense to have the `show_object()` method also on the controller instead. I think both need it, there are use cases for both.

I put "Translucent: accumulate each point using apha in the colormap" at the top because it's most important for our rendering purposes :)

Question: is the PBR model here compatible with blender PBR materials? It would be really cool if we can support the PBR material files you can download/purchase online for blender....
