[osg-users] View::setCameraManipulator
Hi, is there a reason why View::setCameraManipulator method also sets the manipulator node? It seems that this method does more than what it states. In particular if I already set a node into the manipulator calling setManipulator erases the previous node.

[osg-users] Enabling instancing should automatically disable display lists
Hi all, I found that OSG has display lists enabled by default on Geometry objects and it remains enabled even if instancing is enabled. This made for a fairly long and non-intuitive debug session as I was trying to figure out why my geometry failed to be drawn. Ultimately, I just had to setUseDisplayList( false ). According to the OpenGL spec. The error INVALID_OPERATION is generated if DrawArraysInstanced or DrawElementsInstanced is called during display list compilation, which is what finally clued me in. Wouldn't it makes sense to automatically disable display lists in the case instancing is enabled? Otherwise what is happening is very much hidden under the framework and not in a good way.

[osg-users] Compositive viewer and FBO's bug
Hello, When using a composite viewer, views will not change focus correctly if the associated camera per view has render target implementation as FRAME_BUFFER_OBJECT. The function is generatePointerData in CompositeViewer.cpp. It only checks for target implementation FRAME_BUFFER I brought up a similar issue here: http://forum.openscenegraph.org/viewtopic.php?t=12283highlight= Thanks, Chris. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=58414#58414 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Enabling instancing should automatically disable display lists
How would you propose this work? Instancing is a property of the PrimitiveSet, and display list usage is a property of the Geometry object. Would you modify Geometry::addPrimitiveSet() to look for use of instancing, and if detected, disable display lists? What if the instanced PrimitiveSets are subsequently deleted? Would you need some way to save the original setting of display lists so that it could be restored? -Paul On Mon, Mar 3, 2014 at 12:09 PM, Trystan Larey-Williams trys...@trystan.org wrote: Wouldn't it makes sense to automatically disable display lists in the case instancing is enabled? ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Removing Configurable Origin In osgWidget
Sorry to dig this back up, What's the best way to flip the coord system for osgWidgets. Top Left (0,0). Is there an easy way in osg? Or do I need calculate widget position with resize events? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=58417#58417 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
