Hello All,
We are using OsgDotNet and noticed a couple of things we would like to ask
about.
1. We noticed that the quat multiply is not exported in .NET. We saw that
this was because of the OsgIntrospection not properly exporting some of the
overloaded operators, so there are probably other
Hello All,
I have been working with Phil Tessier on some work using OSG in a managed
code environment. We tried using OsgDotNet, but we had some problems with
that, and others on this list recommended we use C++/CLI directly to wrap
just what we need form OSG directly, and there is an example
AHA!!!
I found out that the problems I was having are only on the RELEASE
versions. When I link to the debug versions of the OSG libraries, all seems
to work well. Anyone know why?

Thanks,
I had done that originally, but I would get the crash if I was linking to
release OSG from either the debug or release versions of my app. For the
time being, I link to the debug versions OSG from both my debug and release
versions of my app, which seems to work. I would of course like
One other thing,
When I downloaded the osgNetDemo (It was EXTREMELY helpful, thanks to you
hesicong2005, is that you Ralph?), it was not fully set up in release mode.
It was hooked up to the debug libraries in debug mode, but not hooked up in
release mode at all. I get the impression that it was
Ah, yes. that would do it. I am not creating a graphics context at all, just
using the code I showed above. I can do that (all though it seems
unfortunate.) Is there a utility already in OSG that provides this
functionality?
Thanks,

Hello all,
I am wondering about the best way to record some aspect of a scene that is
playing from a game. Quite often in games when your character gets killed,
you want to see an instant replay of getting killed. The camera motion in
these cases is probably overridden to show the reverse angle
Oh, I almost forgot the thorniest thing I am trying to understand ...
In the game I am using particle effects for things like vapor trails,
explosions, smoke, etc. They seem to have their own relationship with time,
and I do not know that they are rewindable. Lets say that I am in the
middle of

attentions on understanding OpenSceneGraph and optimizing where he can,
where most of the client game code dealing with the scene graph is mine). I

Hi Robert,
I got the stats handler working on our scene and displaying. I am not sure
I understand what the different numbers mean and how I might work with
them. I can see the optimization effort is a big deal. I know it is beyond
the scope of this group. Are there any resources out there to
Hello all,
I recently added a stats handler to our game viewer. Something I noticed is
that if you have the stats window open, showing the bars, that the draw bar
grows and grows. The framerate starts dropping and gets slower. If I turn
the bars off, the framerate returns to 60. When I turn
Something else I noticed that I thought was strange was that the orange GPU
bar has 8 short blocks all drawn in the first frame. I have included an
image to show. What does this mean? When I look at a smaller model, the
Orange block fills alll along the lower bar.

Hello All,
I have been trying to get my scenes to run faster, balancing my scene graphs
using LOD. I use quite a bit of UV mapping in my models, and they can be
fairly high res because I want them to look good up close. There are
usually several instances of the same model in the scene, all
It seems that getting a driver update did the trick. I have a pretty new
setup, so I was surprised there would be new drivers out there, but indeed
there were.
Now I do not have the growing Draw callback, but everything still shows the
orange bar across the entire screen. I am getting 60 fps
Hello All,
Is there a way to use image maps with some of the other material properties,
like emission or specular or diffuse? I am working on adding some

Hi J-S, et. al.
When you mention caching the intersect visitors, when should you use reset()
and when are setStart()/setEnd() used?
In my game, I keep simplified, bounding box representations of the ships in
the scene and then do line segment intersections. When I do the
calculations, I start
Wow, that sounds pretty fantastic. How do you integrate Adrian Egli's K-D
tree implementation into an application that uses OSG?
I appreciate all the hard work everyone does. I appreciate it to the tune
of $25. (actually, I appreciate it much much more than that, but it is
about all I can
OK, I could not figure out how to donate to OSG (I looked for a link on the
OSG site and did a search for 'donate' with no joy).

Hello All,
I am going to be teaching my first semester as a part-time adjunct professor
at BYU-Idaho. I am really EXCITED! We will be teaching an intro. to
graphics course that has not been taught before at this school. Our focus
will be on juniors and seniors wanting to get out in the
Thanks Simon,
A CSG library would be a great idea to work on. I needed one of those for
some work I did with Northrop Grumman. The generalized extrusion function
is cool too, maybe for a single student or as a feature of the CSG library.
I didn't look too deeply, but does the gts library work
Thanks Paul,
Lots of great project ideas.
We are looking for text book kinds of materials. Do you have
recommendations in that regard, perhaps something you and Bob have already
written? Like I mentioned, I would really like to start off with OpenGL and
then show how OSG helps.

Hi
Hello All,
I have noticed that for the past little while the plugins are compiled to
their own directory with the version number. I am not quite sure why this
is beneficial, it seems like you would always want the plugins compiled with
the version of OSG you have compiled, and it seems that
Thanks for the help guys, and the reminder to check the previous posts and

That is unfortunate :(

With the command line SVN it's easy to script whatever you want. I really
think you're making a mountain out of an ant hill. It's useful
functionality, and all it takes on your side is a few more steps (not that
often, unless you recompile OSG extremely often) or a little scripting.

fact breaks other things. That switch is off by default (or ON I should

Something that I have done (please let me know if this is not a good way to

everything else in another part. I then render them in separate render
bins,
Yes, two different groups in the scenegraph under the same camera, but I
cheat the large object part by scaling it and moving it closer to the
camera, so there is no risk of clipping due to the cull settings.
