hi Andy
finally i did what i wanted to do in a different way and ignored the decompose
method.
as far as i know you can ignore the scale orientation quat if the original
matrix is not scaled

Hi guys
I try realize simple clone rendering in two windows
I render scenegraph once then write to texture and show it on 2 windows
so 1 have 2 windows created like this
osg::ArgumentParser arguments(argc,argv);
osgViewer::CompositeViewer viewer_(arguments);

This is one of the offending symbols. Find out why this

There seems to be some problem during the preprocessor step
The normal way to do this, is that you need to break the model in to component
pieces and have a geode for each piece you want to apply a different texture to
using the standard OSG state mechanism and you also have ensure you have the
correct texture coordinates etc.

Hi Aitor,
The most efficient way to render such a character is to use a texture
atlas and have the texcoords on the geometry pick out the appropriate
parts of the character.
A decent modelling problem should be able to do the texture
atalas/geometry generation for you. Doing it as a post

Hi Geoff,
osgViewer::Viewer has a default constructor and will work just fine
without the command line arguments. In fact most of the OSG examples
don't use ArgumentParser at all. So just remove the ArgumentParser
bits and you'll get on just fine.
If all your need to do is geometry queries
Ok, how would I do the geometry queries without it? The only reason I
am using the Viewer is because I was given this project that does what
I need, just on the commandline for a single X,Y, whereas I need to do
it for a bunch of X,Y's in the same database.
Basically, for my project, I need to
Hi Geoff,
Have a look at the osgintersection example for the range of utils for

HiMike,
First of all you should analyze the bottleneck in your application,
osgViewer::StatsHandler will give you the time spent in each traversal.
From the problem you are facing it seems you are draw limited(rendering
a lot number of triangles). One option will be to create LOD(level of
Hi RJ and Mike,
In this case the bottleneck is almost certain the CPU being batched
bound by the large number of separate nodes and drawables, use of
LOD's won't help at all as won't cut down on the number of nodes and
drawables. To solve the bottleneck one will need to merge the
geometry data
Ok, forgive me if this is a basic question, as I am just starting out with OSG.
I have a project that I was given that runs via the commandline,
creates a osgViewer::Viewer based on the arguments passed via the
command line and then retrieves all Z values at a given x,y location.
Right now I have
Hi Paul
Thank you very much for your reply.
I think it will be easier to take the solution #2. For our application, the
only restriction we have is that we must use a single vertex array. But if
you say that this is possible to do even when using different geometries, I
will investigate more
Hi Roman,
It could be that the vista drivers don't support sharing contexts.
It also could be that the reuse of the Traits objects for both context
is the problem - I've never tried this and wouldn't recommend it, so
please just use a separate Traits objects.
Sharing contexts is also something
I have dug down on this problem during the day.
The problem is that the code that checks if ATOMIC should use GCC BUILTIN fails.
I have traced this failure to the combination of the XEON processor and GCC
version.
But if I forces it to use GCC_BUILTINS and compiles OSG and my code with the
Ok, I am looking at the example, but since this is new to me, some of
it isn't exactly clear. It looks like it is running things a couple
times. When I run the project with my .FLT file, it doesn't give me
any intersections either. Is there something special I should be
doing?
Also, since there
Hi folks,
I'm actually integrate osgWidget as GUI library in our engine. I know
it's beta status, but it's pure OSG and we think a better solution
than other third libraries like CEGUI.
My first test are working well. Now i try to extend simple things,

Hi Goeff,
The special thing you need to do is be patient with learning new
stuff. The osgintersection example does lots of different tests, you
needn't do them all. All you probably need is an IntersectionVisitor
and LineSegmentIntersector.

Hi Jeremy,
thanks for your fast reply.
You shouldn't have to manually set the texture coordinates like that if
you don't want; you could use -setImage(..., true) with the right Y
setting in the WindowManager and it should behave how you want. Either
way is fine, though. :)
Yes i know, this

IIRC, they've been having power trouble in the facility that hosts the
