Hi KK,
Just had a chance to try out your fix for the OpenFlt Optimizer crash. Seems
to work for me. Thanks for that
Mark
Hi
the problem causes osgUtil::Optimizer in stage MergeGeodes
crash conditions:
Visual Studio 2005 (VS80)
debug version osg (and host app)
some scene with group that contains some Geodes with various Nodemask
optimize scene (MergeGeodes)
crash cause:
Predicate LessGeode is bad in principle.
struct LessGeode
{
bool operator() (const osg::Geode* lhs,const osg::Geode* rhs) const
{
if (lhs->getStateSet()<rhs->getStateSet()) return true;
if (lhs->getNodeMask()<rhs->getNodeMask()) return true;
return false;
}
};
This predicate sometimes not fulfil condition
(lhs < rhs) && (rhs < lhs) != true
Debug version of STL map in Visual Studio verify this condition and may
crash on assert.
Isolating "same" geodes in 2 steps (2 maps) solve this problem.
