Hi,
I'm having problems when I try to convert a lagre obj file (~600MB) into

Is there any solution or workaround ?

Hi,
do you have problem with not enough free memory or do you hit 2GB per 32
bit process limit in MS Windows?
In second case, if you use Visual Studio, you can enable

Could you use the osg::TransferFunction1D class to help build an
