The limited max texture size will only be an issue if the source data is larger than 256x256. I presume it's the hardware/driver which is causing such a low max texture size. I'm afriad the hardware you have probably isn't a good base to work from for volume rendering. The Geforce 5600Ti I'm using has a max texture 3D size of 2048, which is the type of system one should be targetting for volume rendering, it's really too demanding for low end graphics. > isha@isha-laptop:~$ /usr/local/share/OpenSceneGraph/bin/osgvolume > bin/Skull-2mm/ -o test.osgb > Max texture size=256 > (-0.0625 -0.0625 -0.0625 -0.0625) (0.0248718 0.0248718 0.0248718 0.0248718) > bin/Skull-2mm/ > Min value -0.0625 -0.0625 -0.0625 -0.0625 > Max value 0.0248718 0.0248718 0.0248718 0.0248718 > Single image 1 volumes. > isha@isha-laptop:~$ md > md5sum mdatopbm mdeltree mdu > md5sum.textutils mdel mdir > isha@isha-laptop:~$ md5sum test.osgb > d6e166dd334428d8da6a90ffdbf3d04b test.osgb > isha@isha-laptop:~$ I've tried artificially limiting the texture size to 256 on my system by still get a get different check-sum. I can't say whether this is siginificant. There is chance that changes to svn/trunk OSG are having an effect. > Also i was wondering, how feasible is it to load vtk images into > openscenegraph?? The dicom plugin has an example of using ITK to read dicom images and then converting these to an osg::Image, so have a look at src/osgPlugins/dicom.
