Re: [osg-users] OpenGL commands
Hi Hugo, As Paul mentioned Producer/osgProducer will still work fine with OSG, although there might be need to tweak to get things compiling - essentially there is no major changes to the OSG that should cause significantly incompatibility. However, I would recommend moving to osgViewer if possible as it offer better integration with the core OSG than Producer provides, as well as additionally thread support and more complex viewer configurations. OpenGL is possible right now via Camera callbacks as well, or via extending the scene graphs Drawable. It should also be possible to subclass from GraphicsOperation an attach this to a GraphicsWindow. Which method is the best way for you is hard to say, I'd say a Camera post draw callback would probably the quickest one to prototype. Robert.

Producer should still work with current OSG. -Paul -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hugo Juarez Corrá Sent: Sunday, June 08, 2008 8:38 PM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] OpenGL commands Hi Robert, Thanks for you response.

Re: [osg-users] OpenGL commands
This _might_ be covered in the FAQ on the wiki, not sure... Did you check there? Regardless, certainly one way to do this is to attach a DrawCallback to a Drawable in your scene, then execute your OpenGL commands from the callback. See the osgcallback example for how to create and attach your own DrawCallback. -Paul -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hugo Juarez Corrá Sent: Wednesday, June 04, 2008 3:10 PM To: osg-users@lists.openscenegraph.org Subject: [osg-users] OpenGL commands Hi All, Can I use OpenGL commands directly on osgViewer (without a wrapper)??
