Hi,

I would like to export 3D Volumetric data to some "standard" format like VRML, X3D or PDF (which is now capable to handle 3D graphics), but I've noticed, that however there are some new format specifications (e.g. for X3D), that provide some way to save volumetric data, the problem is, that there is only a few (or none) visualization tools that can handle these new format extensions. Or am I wrong?

As far as I know, there is always good support for mesh geometry, but Volumetric data are a bit different story...

Could someone suggest some format for volumetric data export, that is wide-spread and the viewers as well (freeware in best case)?

Thanks a lot.
