Hi Robert Delport,
I have the setup with 4 cameras:
1st camera - the slave camera that inherit the master camera's relative frame
and render the scene to 2 textures with color attachments. One of the texture
remains as it is and other texture is left for further operation.
2. 2nd camera -
Hello guys,
Sorry for my late reply, I had a very busy weekend. :)
What I actually want is to traverse the whole graph 3 times. (that's why I have
three cameras). And each time to draw a different submesh (see the nodes at the
bottom). Each time I traverse the graph I want nothing to be

Hey,
I just use: mycamera-setClearMask(0); for all the cameras.
I don't do any other 'special' initialization.
You can also check the attached source if it helps.

Hi everybody,
I'm new to OSG and from what I can see I regret I havent come here sooner.
Before I start, I have a few questions.
1. Is OSG free to use in commercial software?
2. How does OSG handle windows? Is it built in or requires 3rd party sw?
3. Any experience and/or thoughts of using Qt

Hmm.. maybe there is something wrong with the cpp file I attached.

Hi,
the strangeness ito depth disappeared when I added:
camera01-setComputeNearFarMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR);
camera02-setComputeNearFarMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR);
So, I think the auto compute of near/far is breaking your depth buffer
consistency.

Hi
I'd like to use curves, particularly simple 2d control point based splines
to drive variables of scene graph objects over time. I'd also like to use
both linear and cubic interpolated
Thanks for the link jago, osgModeling certainly looks comprehensive!
For the time being, I implemented the Catmull-Rom spline, which serves my
purposes ok.

How about just trimming off any invalid characters from the name returned by

e.g.

Hi,
Using the gDEBugger I found some VBO leaks on application exit.
For example the leak could be easily seen if we add useVertexBufferObjects
TRUE into cessna.osg and will try to render it via standard osgviewer.
OSG calls releaseGLObjects before exit for the loaded tree and for Geometry it

I have just reviewed the relevant code Array's are no implementing the

I have very specific problem which I don't know how to solve with OSG.
I want to create very large texture atlas (4096x2048) which consists

Each of small textures should contain some textual/symbol information

I've got a problem with compiling OSG for GLES1.1 on Ubuntu. I have the

succesfully compiled for GLES2.0 before on this very system (also have

I saw a similar error when upgrading from Fedora 13 to Fedora 14, which
uses a different version of gcc. In my case the solution was to remove the
contents of my .ccache directory. More generally, I think this problem comes
from mixing object files produced by different g++ versions.

Hi J-S,
you are right using NOMINMAX avoids the problem. I tracked it down to osg/GL
and the inclusion of gl3.h:
Code:
#elif defined(OSG_GL3_AVAILABLE)
#define GL3_PROTOTYPES 1
#include GL3/gl3.h
#ifndef GL_APIENTRY
#define GL_APIENTRY APIENTRY
#endif // GL_APIENTRY
Hmmm... I can't seem to find any .ccache directory or file...
I *thought* I recompiled and reinstalled everything in OSG and my software,
but I'll do so one more time.
Any other ideas out there?
Thanks,
John

Hi Steve,
sorry, I might have asked this the previous time as well... Have you
checked the thread affinity of the different threads? Are they not bound
to a single CPU? AFAIR the osgviewer used to set its affinity and all
