Suppose I define a tachyon scene
sage: s = Tachyon(xres=512,yres=512, camera_center=(3,0.3,0))
and I define a torus and a 3d plot
sage: from sage.plot.plot3d.shapes import Torus
sage: t = Torus(0.5, 0.2)
sage: p = plot3d(lambda x, y: x^2 + y^2, (-2,2), (-2,2))
How can I add `t` and `p` to `s`?
I know I can do `s.str()` and `t.tachyon()` and `p.tachyon()`
to get strings depicting `s`, `t` and `p` as tachyon scenes,
so I could fiddle with these strings, but is there a better way?
For instance, if I have a string depicting a tachyon scene,
can I turn it into a Sage tachyon scene, extract its objects,
add them to another scene's objects?

https://ask.sagemath.org/question/33320/add-a-3d-graphics-object-to-a-tachyon-scene/?answer=34859#post-id-34859This has been requested from time to time in the past. Functionality to do this automatically is definitely something we'd like to add to sage. There is an open ticket, and there you can see a few different approaches that people have given in the past. Hopefully one of them will help you with your task!

Unfortunately, there isn't any active work on choosing a method and including it into sage. Any effort would be welcome :)
