Hi Jason
Well, I tried once with the nvidia-drivers as well and I got a segfault
in libGL instead, but I will try again.
This was on a Gentoo Linux, not on a Fedora, but the versions of
nouveau-drivers, mesa, qt and openscenegraph were basically the same.
While I could reproduce it on Fedora 16,

Do none Qt OSG apps work OK?, i.e. osgviewer, osgcomposteviewe etc.

I'm finding to parse exactly what is amiss. Is it that you are trying
to create a geocentric database? Or do you want to destination
coordinate system to be in epsg:3785. Geocentric is computed in

Hi,
I'm having problem with concave polygons.
If I use osgUtil::Tessellation it destroys information, that this was a
polygon, so I have two options, glue it together or save data (which is memory
consuming). It can be done, but the worse problem is in outlining them
afterwards with
Hello,
I am so dissatisfied at the moment. I render my scene into a texture and put it
on a quad. I want use shadow maps in my scene, so I have to use a slave camera,
because shadowmap technique doesn't work with nested cameras. But my problem
is, all my callback function doesn't work now. The

Hi,
I am using osgShadow::ShadowedScene to render shadows. This works fine with
every technique as long as I am not using a castsShadowTraversalMask. If I
set the mask to anything diffrent than 0x the shadow looks like a
quad.The correct nodes casts shadows but the shadow looks wrong.
Hi, Martin
I am assuming you are complaining about limitiation of techniques derived
from ViewDependentShadowTechnique. If thats a such huge problem for you then
you may try to fix ViewDependentShadowTechnique to use RenderStage ptr
instead of CullVisitor ptr to index ViewDependentData. That

My mistake. I didn't catch that in your original message. Sometimes I

Hi,
I am new in 3D tools and I am trying to compare several ones that are popular
... Sorry if I am a bit confused.
Could someone give some kind of comparison about the main differences between
Unity3D/OpenSceneGraph/Vizard of WorldViz if they could be compared?
We are looking for 3D tools

You might also want to consider VR Juggler, which can be used with
OpenSceneGraph. I've built a set of bindings for VR Juggler and
OpenSceneGraph and some extended capabilities that allow interpretive
scripting (in Lua), as well as interactive code execution - it's called VR
Thanks Ryan,
I forgot to mention VRJuggler that I am considering too since we are going
to use several input/output devices inside the CAVE.
Certainly, I will have a look into your VR JuggLua.
My concerns is about comparing the pro/con features of these tools, like
commercial vs. opensource, I
Hi,
Thank you very very much for your reply. I will post the algorithm up once I
got it up and running. From your suggestion, at least now I have a better
direction to search for the solution.
I can't really do the CUDA inside the osg loop, mainly because i need the cuda
to run as fast as
