Found two different ways to tell OSG that vertexs were modified.
Maybe these are circumventions that aren't proper (?).
What is the "one right way"?
Call dirtyDisplayList() ?
ctor()
: mVertexs(new osg::Vec3Array),
mDrawArray(new osg::DrawArrays( osg::PrimitiveSet::POINTS,0,0))
{
}
Hi!
More division by zero trouble, this time in
include/osgDB/DatabasePager line 331:
double getAverageTimeToMergeTiles() const { return
_totalTimeToMergeTiles/static_cast(_numTilesMerges); }
Obviously divides by zero if _numTilesMerges is zero.

That's not utterly insane, but many older PC's won't be able to

On my current machine the burst transfer rate from cache (ie memory to

Hi Alan,
Even if you get your billboards to cast shadows, the result is usually
unpleasant. Most of the time your billboards will appear to be split
down the middle with a dark half and a light half. This is because
the billboard has a different rotation with respect to the eye and the
light sour

You may be hitting up against a range of issues, but without more info

osgGIS is probably what you want to use. It reads feature data via OGR and
creates nice OSG models for your feature data. I believe it could read VMAP
data by changing to the URL used for the filename. I don't recall right off
hand how you do that for VMAP data, but I do know that its

Hello Robert,
The OSG nodekit delivered with the SDK, existing today, is supporting version
1.0, 1.2 and 2.0.
But actually with the API, also delivered with SDK, you would be able to modify
the nodekit and adapt it to any versions.

Gus,
I quickly glanced over the 1.5 spec to see what the kinematics is all about.
Seems interesting, but there's probably a lot of functionality missing in osg

It could be a very useful addition, but then you would also

Hi,
When you compile, your compiler will generate theses files ...
If you use Cmake, you would not have this kind of problem... Tell us more
about how you did that, what you use...
