Okay guys !
I've just tested this on linux, and the command:
*osgvolume --raw 256 256 256 1 1 big bonzai.raw
worked just fine !!!
*So I guess this problem is only on Windows.
The good news is, I also did:
*osgvolume --raw 256 256 256 1 1 big bonzai.raw -o bonzai.dds [on linux]
*then used the generated dds file (which has a much bigger size this time
!!! :-) )
*osgvolume bonzai.dds [on windows]
And this time, this worked too !!!
**
==> So my fisrt impression is that the issue is only related to the
generation of the 3D image somehow. I don't have time to investigate this
further right now, but I might come back to this issue a bit later!
Thanks for your support guys !
Now I finally got a volume rendered on Windows, that's nice !!!
Cheers,
Manu.
