Hello,
Back to front sorting in the transparent bin did not work in our
application on linux since quite a while.
Once we used CMake to build OpenSceneGraph, it worked correctly but our
application was three times slower than before.
It turned out, that I forgot to add -DCMAKE_BUILD_TYPE=RELEASE to the
cmake options and thus got a non optimized osg build.
With the optimized build I got decent framerates again but geometry
sorting did not work anymore.
It turned out to be CullVisitor.cpp in osgUtil which causes the bug to
appear if compiled with -O3 and disappear if compiled with -g.
The solution to the problem is not to inline the distance function.
inline CullVisitor::value_type distance(const osg::Vec3& coord,const
osg::Matrix& matrix)
we had this issue with
gcc-4.0.2
gcc-4.1.2
gcc-4.1.3
and other versions.
Robert, could you add a #ifndef __GNUC__ to the inline declaration or
convert it to a macro?
Uwe
