Hi Hesicong,
osgVolume doesn't directly load or require any particular file
format,so you can use it with an 3D osg::Image data that you have.
The OSG's dicom plugin can generate such 3D osg::Image by reading a
directory of dicom files if you use osgDB::readImageFile() or a
complete VolumeTIle node with all associate data and rendering
techniques set up if you use osgDB::readNodeFile(). You can select
the the dicom plugin for reading dicom directories by appending a
.dicom to the end of the filename i.e.
osgviewer CardicCT.dicom
The osgvolume example with append the .dicom automatically for you so
you can do:
osgvolume CardicCT
Examples of dicom files can be found on the web, and I don't plan to
add these of OpenSceneGarph-Data as they are typically very large -
often hundreds of Mb, and also I don't have copyright for them so
can't go including them.
A couple of example of dicom files can be found on the Osix website:
http://www.osirix-viewer.com/Downloads.html
I've come across other sample dicom on the web, but a quick search
with google didn't pick up on links to these, I'll populate a wiki
page with links once I track them down.
Robert.
