I'd like to obtain a figure like the image below, with transparent (maybe white) background but for a torus surface.

I'm checking Google for hours but no success. Any idea where to look for?

In resume: I'd like a sphere and a solid torus with the same size (the same bounding box) and the same texture (not necessary the same colors as below) and white/transparent background. Also it could be nice if the view point shows the hole of the torus.

ps: I found (very pretty) this one (striped version) but the background is not white and it is not solid.

    The second image is composed by Villarceau circles. You can find some nice examples here with POV-Ray sources too. You can edit the sources, remove the backgound and render a new image. – Paolo Gibellini Oct 10 '14 at 5:25
  • @PaoloGibellini seems to me they are torus knots instead of Villarceau circles. Because thet wrap around poles. – joojaa Oct 10 '14 at 13:57
  • @joojaa, sorry but I have no idea how to do that. I don't work with design and so I only need some reference to look for the figure. I'll use it on a math talk. I could use another figure but I'd like both with the same texture. – Sigur Oct 10 '14 at 13:58
  • Yes, they are knot torus. But it is only an example. If the torus is solid, it would be better. I'd like both surfaces with the same texture. I'll use on a talk. – Sigur Oct 10 '14 at 13:59
