[osg-users] Building KdTrees

[Robert Osfield]

Hi Ale,

There isn't any way for me to know what might be amiss with the
details provided.

You have your code, your data and the potentially the whole OSG source
code (it's easier to debug if you've built the OSG yourself) so should
be in a good position to step through your own and the OSG code to see
what is happening.  For instance putting a break point into the
OpenSceneGraph/src/osgDB/DatabasePager.cpp where the kdTree code is to
see whether it's being invoked and if not why not.  This should give
you clues to why things aren't working as desired and how then you
might fix them.

Robert.
