Q: I'm having a problem using a PrimitiveSet to represent a single point, OR my geometry seems to dissapear as it gets very far away. What's wrong?

Hi,

Please help me understand this behavior: I'm playing with the
osgpointsprite example, and I'm changing only line 40, that originally
looks like:

galaxy->addPrimitiveSet(new osg::DrawArrays(osg::PrimitiveSet::POINTS,
0, nvertices));

In particular, I'm changing the "count" variable in osg::DrawArrays,
originally set to nvertices. If I use count=3 I see 3 points. Good. If
you set count=2 I see two points, great. But if I set count=1 I can't
see any point! This line 40:

galaxy->addPrimitiveSet(new osg::DrawArrays(osg::PrimitiveSet::POINTS, 0, 1));

produces an empty scene, instead of a scene with one point. What am I
missing? Aren't size=1 arrays supposed to work?

Thanks,
Pasquale
