Hi Robert,
We are using OSG 2.8.2.
The problem we encountered was when the TriStripVisitor was used with
double data (e.g. for OpenFlight with double precision). As far as I can
remember in this case the wrong member function (remap(...)) in the
base class was used. That's why we had to add those additional
overloads. Otherwise we later encountered crashes with indices pointing
to Nirvana.

We found a bug those days in TriStripVisitor.cpp. I didn't really read your
latest email, but this might be related to your precision issues:
What bug was this? Could you explain? Which version of the OSG?
class WriteValue : public osg::ConstValueVisitor
{
...
// add those 3 lines
virtual void apply(const Vec2d& v) { _o << v; }
virtual void apply(const Vec3d& v) { _o << v; }
virtual void apply(const Vec4d& v) { _o << v; }
...
}
class RemapArray : public osg::ArrayVisitor
{
...
// add those 3 lines
virtual void apply(osg::Vec2dArray& array) { remap(array); }
virtual void apply(osg::Vec3dArray& array) { remap(array); }
virtual void apply(osg::Vec4dArray& array) { remap(array); }
...
}
And these lines do what? To address what issue?
Robert.
