POVray (1) - There are quite a few tests for spatial perception. Probably all of them differ somewhat, but one specific test is almost exclusively used in German-speaking countries: the “Schlauchfiguren-Test” (tube figures test). And not infrequently—since it is part of the aptitude test for medical school. Sometimes this aptitude test is required for admission to medical studies, while in other years it isn’t. That’s why I’ve occasionally come across practice tasks for the tube figures, usually still in book form.
POVray (2) The “tube figures test,” briefly explained: Imagine a transparent cube. Inside the cube is a thin tube, partly coiled and knotted, arranged more or less at random. Now you see the cube directly from the front—and with it the tube figure. A second image then shows the cube, with the same tube figure, but viewed from a different side. From the left, right, top, bottom, or back?
POVray (3) While playing with the idea of digitally building such a tube figure myself— using a simple tool but still achieving a proper result—it occurred to me that POV-Ray might be a good choice. Back in the 1990s I experimented with POV-Ray. I was impressed with what was possible, but disillusioned by the hours-long rendering times.
Has anyone here gathered experience with POV-Ray?

I remember povray from a very long time ago, and indeed even on a >beast< 166Mhz we had, rendering times were a pita.
Today ray-tracing is a coolest kid on the block, so I'm guessing pov-ray performance is much, much better, although I have to admit, I haven't looked at it recently, but...

Depending on your preferences, but I think blender might be much better suited for that job (if this is a one time thing)

@gim Thanx, Blender is probably the better choice. I’ve always been a bit put off by how complex it seems, but with the right tutorial it looks like it can actually be done in just a few steps. Another nice bonus is that I could 3D print the model as an STL file. With a transparent filament, it might be worth giving it a try ...
