Re: [osg-users] Saving the result of an IntersectVisitor
Ooh, that could work! Thanks, Terry, I will try that. -Todd On 08/25/2010 05:58 PM, Terry Welsh wrote: How about just a vector of vector of integers?

Re: [osg-users] Saving the result of an IntersectVisitor
Another idea I had was to use a NodeVisitor to predictably - probably sequentially - name each node in a model after I load it. They I could record a NodePath as a vector of names. This idea is my current favorite, but I'm still hoping for an easier solution. -Todd On 08/25/2010 08:44 AM, Todd J.
