Hi,
I have an issue of installting OpenSceneGraph in Linux (CentOS 5.5 to be exact).

Desktop: /home/carlodm/
* I installed CMake 2.82 from Source
* Also, I installed g++, and gcc using yum
I am at the part where I

Remember that when compiling, you also need the development packages for
every library you want to use. From the errors I think you haven't
installed the headers for OpenGL.

Hi,
I have a problem loading multiple collada files into osg.
here's the code:
osg::Node* node1 = osgDB::readNodeFile(tank.dae);
osg::Node* node2 = osgDB::readNodeFile(hand.dae);
There's an heap allocation exception when the code is trying to
load the second dae file.

Hi Brian,
There isn't enough information for others to begin suggestion what
might be amiss. Could you provide a stack trace and information about
the OSG version/Colldada version/OS version/nature of the models.
Thanks,
Robert.

The author specifically mentions OSG. The Qt scene graph research is still
mostly to improve 2D and 2.5D interfaces. It seems like they agree that OSG

I know that XPlane has an interface like this as well, but that is not

I read up on that a bit. Sadly, we use things like #import, incremental
compilation, and precompiled headers. All these are incompatible with
the new multi-process build switch.
Besides, our application is actually composed of a bunch of sub-projects
and these are all compiled in parallel. If I

I read the bvh file correctly:

I've just downloaded the latest version of OSG from svn, I tried the FBX plugin
but I've got no reflection map in my models.
Are reflection maps not supported yet by the FBX plugin?
I'm using FBX 2011.2 (both for the SDK and for the exporter in 3dsMax).
Thanks.

Hi Sanat,
the intersection test gives you lots of informations, including the normal
of the face interestected you would use to orient the model. There is a code
in the terrain (or drive) manipulator that folllows the terrain. Have a look
there

Hi,
I have started working on openscenegraph since a few weeks. I was able to get
to a point by looking at some online exapmples especially the NPS tutorials. I
also have the pdf of the QuickStartGuide by Paul Martz which was useful too.
I also got a lot of help from the other users in the osg

Hi Peter,
Just I did notice that for long/skinny objects the bounding sphere is a very
poor fit. One option for me is to dig down and get the boundingBox() of the
drawable that lies as the basis of my geometry. In my experience, that can
allow for a much tighter fit for this type of selection.

I'm going through the changes to see how I might have my

Hi,
as far as I know, you can only make rotate/translate/scale once on a matrix
because it resets the prior values.
But you can always create a matrix as you did, and add its operation via
multiplying your temporary matrix with the final matrix. This way you can sum
up your operations in
