No. But in the sources of white_dune there is a small shellscript,

white_dune-0.26pl4/tools/povray_mkskybox.sh

that builds a VRML background {backUrl, frontUrl, ...} from a
povray file.

How about a sphere (but as indexedfaceset) whose faces are visible for
the inside, and you put it all around the scene. Either put a strong
creaseAngle at the IFS, or don't put a material in the appearance,
only the texture.
I say sphere instead of cube because the geometry is less guessable
when moving in the scene.

Please check out my space odyssey site to see my treatment of stars. They are
points and are randomly generated then DEF'd and USE'd filling all six sides of
a cube. The cube then follows the viewer but does not rotate with the viewer.

MetaTooly Bryce can do this. You can make magnificant backgrounds without
seams with this tool. Here's the link taht describes how:

Thank you,

I'd like to try this solution, but I don't succeed to build a scene with a
sphere visible from the inside ...
(I succeeded with a cube cutted by a sphere, but the texture is strange,
it's not nice when I examine the scene.)

Could you help me ?

Thx !

Hi Alex, A stunning model and the stairs are ace! Just as a matter of
interest did you have a different renderer selected in the scene as it
crashed my machine a couple of weeks ago. Glad to say it works fine
now.

Thanks for the compliments. I don't make my website choose a renderer for you (like
Cortona or Cosmo) if that's what you mean. Whichever is your default vrml browser
on your machine is what will render my wrl files.

I chose points because they seem more realistic and the speed of navigation is not
as choppy, greater frame rate.

Please email me personally, I am curious about your problem.
I cannot reach your email address.
