Hi Robert,
osgSim::LightPoint only support a single colour, so you'll need to use
two and differentiate using a osgSim::Sector.

If you turn on "Wait for vsync" in your video drivers, it will limit
the frame rate of your app to the refresh rate
Hi,
I want to generate a grid. I have done this with triangle strips, but I
want to try to do it with the triangle primitive instead.
Is it possible to define vertices in one array, and vertex-indices in
another array that forms the triangles, for example:
The indices:
00 01 02 03
04 05 06
Hi,
I'm new to OSG..
I compiled OSG on my Linux box, and I see that any OSG application I

like I open osgviewer with a model (say cow.osg), and then don't touch
the window (no rotation, zoom,etc.) - and top shows the viewer takin

Hello again WuCaihua,
Some preliminary feedback:
* Some minimal information on what to do with the contents of the two
rar files
and the data rar would have been useful. The readme has the keys
and some info
on settings in the ini file, but nothing about how to actually run the demo.

Robert,
Could you please explain what you mean by "slow path" in this case? I was
under the impression that glDrawElements and glDrawArrays were basically the
same except that the former expects indices and the latter assumes your
verts are in order.
Thanks for the clarification. -gw

Hello Paul,
> Well, I'm not sure this is a good OSG coding example :)
The point I think is that once it's in SVN we can improve it more
easily. Getting the first version of something is the hard part, then
it can be incrementally improved very easily.
Thanks in any case, it's a useful tool.
in fact, what paul says is very similar to what i often do in test apps:
while ( !viewer.done() )
{
usleep( timeToSleepToGetMeToMyDesiredFrameRate );
viewer.frame();
}
in a more commercial-style app, i'd recommend only redrawing when data
actually
changes. so in a cad app, when

Hi Joakim,
Always prefer osg::DrawElements* over vertex indices and DrawArrays as
the later will force the OSG to dispatch using OpenGL slow paths.
glDrawElements/osg::DrawElements is by far the best way to dispatch
data to OpenGL.
Robert.

You mean to be able to see the scene graph in osgviewer? *That* would

Hi WuCaihua
I've tried to download and launch your demo and I get the same error
as Jean Sébastien. I am using WinXP SP2 EN.
It seems that at at least 1 DLL is not found (dwmapi.dll, saw that
with the dependency walker) and also that this DLL is part of windows
Vista. Are you running vista? If so,
I've tried writing a start-stop frame loop, and it seems to work fine.
You have to make sure you know when objects are moving in the scene. I
also added a periodic redraw (i used something between once a second and
once every 5 seconds) just so the app wouldn't get swapped out and have
troubl
we'll have to agree to disagree. i think rendering when data hasn't
changed is a bad use of system resources. what matters ultimately
isn't frame-rate, but _perceived_ frame-rate, and if the user is
staring at an immobile object from an immobile view, 60Hz is no better
than 1Hz.

The osgviewer app calls viewer.run(), which is effectively the same as:
while (!viewer.done())
viewer.frame() // draw a single frame
So, if you only want to draw when your app is not idle, then you should n

Ditto Glenn's post. The big "gotcha" I ran into when I modified SimAuthor's

Ellery,
Be sure to account for the DatabasePager if you plan to use PagedLOD nodes.
You will have to check that the pager has no more work to do before stopping
your loop. Another thought... you may need to do something to prevent
PagedLODs from appearing to expire because the cull traversal isn't

Hello,
The Creature3DGame.part1.rar and the Creature3DGame.part2.rar is one file
that compressed into two volumes. Put them in the same directory then
decompress the Creature3DGame.part1.rar.
Can you try it again.

Hi,
I want to read in nodes from a .obj or .3ds file.
For doing this I use
osg::ref_ptr osgNode = osgDB::readNodeFile(snode.filename);
Now I want to get the objects from this file. This shall be a Square, a
Sphere and a Pyramid. I tried to do this by using:
osg::ref_ptr myOsgGroup;
