Hi,
Strange...
My small fog test program works fine on my laptop at home ?!?!
All test cases behave as expected.
Same OSG version (2.2), different hardware and linux distribution.
I still get (at home) the same warning though:
--- detected OpenGL error 'invalid enumerant' after
Hi Glenn,
Your analysis is correct, when the DatabaseCacheReadCallback is
deployed one can potentially end up with dangling pointers.
Switching to ref counted NodePath would be the safest way to fix this.
There is a performance penalty though, which is why a straight
NodePath was used. There

Hi Manu,
Extending the .osg format with your own
callbacks/nodes/state/drawables is pretty easy - just look to see how
all the NodeKits do it i.e. they have src/osgPlugins/osgParticle,
src/osgPlugins/osgText.
The .ive format isn't extensible in the same way though, to extend it
you have to go in
Hi,
You are probably best adding OpenGL calls as part of the scene graph,
by subclassing from osg::Drawable as per the osgteatpot example. Then
just add this custom Drawable to the subgraph below your RTT Camera.
Robert.

Hello OSG mailinglist users,
I have a problem with the osg::IntersectVisitor at osg V2.0.
I will use the IntersectVisitor to detect a hit between a 3Dmodel and a
ray (LineSegment), so I build a testprogram based on the

Yeah, I think so.

Hello,

Well, considering the fact that since about 2000, research in
real-time raytracing has been ongoing, but has relied on distributed
computing (sometimes 40 machines
I'm taking a first look at lightpoints. If I needed a single lightpoint
with half the light sphere green in one direction and the other half red
in the opposite direction, can this be readily done? With a single
lightpoint, or two half lightpoints? Is this what lightpoint Sector
could be used
Hi everbody..!
I have a school project. And I have to create a virtual terrain! And so I want
to use terrapage database format with OSG.
I can't find anything about creating terrapage database! How can I do that? If
anyone has any document,information or internet link about it please let me
Hi Will,
Thank you very much for the suggestion. I will try this out ASAP and will
let you know if it works. By the way, is NVidia aware of this problem? If
they are then they should be fixing this problem.
Best regards, Shamim

Hi Umit,
As far as I know, TerraVista is the only software that can generate
TerraPage format datasets:

But it is probably out of your price range. Is there a particular reason you
need TerraPage format? If not, I suggest you look into
Nvidia has something called CUDA, which is essentially a C-like programming
language that compiles to the GPU. I haven't looked into it, but my guess is,
that's a tool real-time raytracing could benefit from, if it hasn't already.
I think if we've learned anything over the past 10 years or
15 matches
