Re: [osg-users] Problem with my cubemap

Hello Robert, I've originally contributed the .dds cubemap loading capability that you rejected. From that time I've been merging my changes with the latest head. Cubemaps can still be loaded succesfully, but I agree that it may be better to split osg::Image into multiple classes for the

Hello Bilal, code comments in the ShadowVolume class suggest that it is still a work in progress. However it seems that it is no longer actively developed and still has some unsolved bugs. Cheers, Roland -- Read this topic online here:

[osg-users] camera switching on a given view...

All, I have a question regarding camera switching in a particular view. I'm currently using the composite viewer where each view is set up in a separate window (via the call to view-setUpViewInWindow()). For a particular view(window), I need to swap from one camera to another upon request.

Re: [osg-users] No texture loaded on 3d model with osgViewer

Try setting the OSG_NOTIFY_LEVEL and see what error messages you are getting. That should tell you if it can find the texture and where it is looking. http://www.openscenegraph.org/projects/osg/wiki/Support/TipsAndTricks Cheers, Martin -- Read this topic online here:

Re: [osg-users] huds on multiple cameras

Hi again, I tried J-S 's suggestion about attaching the hud camera to a slave camera, but that did not work (i.e the scene is rendered, but there is not hud). viewer.getSlave( 0 )._camera-addChild( hudCamera ); Note that adding the hud camera to the scene (like in the hud example) did work

Re: [osg-users] VRML plugin

Hi Philip, I also note that previous discussion about why the VRML plugin couldn't be updated to a newer version of OpenVRML centred on the boost dependency. I'm sure that thats much less of an issue now that we have boost binaries for most Linux distros, plus Windows and Mac. That, and the
