VRML -> Radiance translator ?

Hi all,

anyone know of a VRML (virtual-reality-marker-language, 3d geometry for
the web)
to/from Radiance translator ? (VRML-1.0 would be fine)

Hi Peter,

I don't have a direct translator to Radiance, but I do have a reasonably
robust two-step process.

Visit http://home.europa.com/~keithr/crossroads/ - there you can download
quite a useful freeware 3d file translator. Using it, you can convert from
VRML (version 1.0 only, I am afraid) to DXF. Then of course you can convert
DXF to rad by a number of established methods (I use torad in AutoCAD, but
of course Desktop Radiance does the same thing).

Hope this helps.

Regards,

Jeff

Ahem... could it really be that anyone is not aware of
the easy way to convert a DXF file yet?

And if you're really *still* using torad for exporting
from Autocad, please have a look at Radout instead!

Have fun!

You can get from Radiance to VRML via MGF, but not the reverse as far as
I know. To create an MGF file from a Radiance description, use rad2mgf.
It won't translate textures, patterns, and some of the fancier
materials, but it captures most of the rest of it. Then, use mgf2inv to
get to Inventor format, which is the same as VRML. You need to use the
-vrml switch to get the correct version header, but otherwise the output
is identical.

The reason there's no translator from VRML to Radiance is because it's
very difficult (in my opinion) to support VRML, plus it's such a moving
target... It requires a parser library and I just never got around to
implementing it. Volunteers are welcome, as always.

Hi!

Is there ANY converter allowing the import of textures into radiance files?

CU, Lars.

ConRAD on http://www.openentry.dk converts a 3DStudio file (including the texture mapping) into Radiance quite well...
The free version doesn't support the textures though :slight_smile:

I have some renderings in my rendering comparison on http://asro.sbuild.com that used it.
