Hi Guillaume,
Just to be clear, it looks to me that the typo was LUMINANACE (an
extra A crept in) which should be LUMINANCE.

Hi,
Sorry for the simple question... I am trying to load a list of images using the
--images flag. Looking at the osgvolume.cpp code in 2.8.2, I don't see how it
can detect *.png like you mentioned, or detect the list of slices from the
filenames. Am I right on this ?
Thank you!
Cheers,
Ho Guillaume,

I haven't tried it yet, but it should work automatically.

I'll see if I can dig deeper in the near future.

Hi guys,
Perhaps you mean the dicom data dictionary?
http://www.mevis-research.de/~meyer/dcmtk/docs_352/dcmdata/datadict.txt
On Mac I had to point to the installed dictionary file:
export DCMDICTPATH=/opt/local/lib/dicom.dic
Otherwise I'd receive an error like this:

Yes, you're right. I remembered having to set the DCMDICTPATH before the
files even loaded, but I think there was also another problem. Will have

Hi Robert,
Congrats on getting all this work on osgVolume done!
To test out osgVolume you'll need to grab OpenSceneGraph and
OpenSceneGraph-Data (for shaders) from svn/trunk. I'll be tagging
2.7.9 very soon, so it'll be in this, and obviously the up coming
stable 2.8 release, but I've very
Hi Robert,
Sounds great. I have never done any volume rendering stuff - but you
