Ok, I'll make small example and show where problem occures. I'll try do this
today.

Can you make a small and simple prototype that *reliably* reproduces
the problem? You have a better chance of getting help that way.

Hi,
I normally like to think about the heading, attitude and bank as just
rotations about certain axes. In osg you can make a quat using e.g.:
// angles in radians, yaw, pitch, roll
double y,p,r;
osg::Quat ori = osg::Quat(r, osg::Vec3(1,0,0),
p, osg::Vec3(0,1,0),
Hi Ümit,
the best way is to have a correct model from the beginning, centered and
aligned with the origin, but if it couldn't be done, you would have to make
the geometry child of a transform that would put the mesh at the right place.
Say you had an object displaced 4 units on the X axis from
Hi Franclin,
The references to the vertices that osg::TriangleFunctor returns point to the
real data of the geometry, so if you subtract their pointers to the first
vertex pointer of the geometry, you'll get the index to that vertex and you
will be able to get its normal and UV coordinates:
Hi,
Sorry, I have no expertise with 3DSMax and/or osgExp, so I cannot help you
further. Nevertheless, here is the osgExp code download page address:

I suppose there are compilation instructions within the source.

The code in Optimizer.cpp makes this look like a bug. If the two were
intended to be synonymous, I'd expect they would share the same code. They
don't. I'm betting FLATTEN_STATIC_TRANSFORMS_DUPLICATING_SHARED_SUBGRAPHS is
supposed to be 0x1.

Agreed. I will go ahead and submit the presumptive fix to osg-submissions.
Thanks Paul -gw

We are seeing an interesting problem that we can not track down.
Several previous postings have been similar but not quite what we are
seeing. We are hoping someone can point us in a possible direction to
find a solution.

I am trying to use OpenFL color matrix functionality through
osg::ColorMatrix but not able to do so. When i apply this to a node

you guys to have a look.
I don't know what am i doing wrong in this simple piece of code
Hi Scott,
Have you setted the pager to not unref images after applying them ? When you
have multiple contexts, you have to make sure images are not deleted before
each context has applied it.

Having never used a ColorMatrix in OpenGL or OSG
What effect is this supposed to produce ?
Do you have screen grabs of what it should look like if done in raw Opengl ?

Hallo.
I have a problem with function viewer-computeIntersections in OSG 2.6.0. When
I tryed get objects throught which goes line function lost some of them (but
line definitely goes throught them). It looks like function can't see some
objects. I tryed run osgpick with my scene but this error

Hi Gordon,
Color matrix in OpenGL is used for color space conversion, for example
using color matric you can convert RGB to BGR , RGB to CMY.
Unfortunately i do not have any screen grabs for the moment, but i am

Hello all,
Under OSG 1.2, I controlled the orientation of an osgGA manipulator
through the use of a coordinate frame callback.
Under 2.4, I am using the same exact code, but the callback never
happens.
Here is the code snippet. Viewer is osgProducer (yes, still).
This loop runs 4 times.
Hi folks,
We deal with a lot of CAD data that has been translated to OSG, and I am
looking into ways to enhance the performance in OSG.
One issue we are facing is that the CAD data is very poorly organized
with regards to the cull process. We had hoped that the spatialize

Hi Todd -- I'd think the Geode-per-Drawable might improve cull performance
in your case, as it's faster to cull against bounding spheres than boxes.
I've been working with complex CAD data for over a year and have had good
results with some models by inserting OcclusionQueryNodes at strategic
Here is the small example, where described problem appeares. Example is
modified example of osgpick (chenged code which returns name of object and osg
scene). To see this problem you must go in the deep of room (way is showen in
00.jpeg). Then you need make several clicks in different positions
(As mentioned in the other discussion thread...) If there is a way to
reproduce this issue with osgpick, please provide explicit steps for
reproduction. Of course if you can debug the issue and submit a fix, that
would be even better.

Hi JP,
I'm new and I'm a little fuzzy on the versioning between VPB and OSG.
It looks like for the example you have provided, we need an older
version (2.3.6) of OSG. Do you know if there are plans to upgrade VPB
to work with the latest releases of OSG or am I totally missing
something?
Thanks

Hi. I'm looking at shadow techniques provided by the osgshadow nodekit for use
in a production project. On the wiki it reads like only ShadowMap is production
ready and all the others have problems. Is this the case? Or have the others
been marked as experimental because they do not work
