Re: [osg-users] High resolution screencast
Thanks to all of you. I'll give a try to the screencapture example.

In my speed reading I have seen mention of the osgscreencapture example that has an option for opening a pbuffer for taking a snapshot. This particular example is setup to demonstrate streaming imagery from the graphics card, rather than taking just a single frame, but the ideas are similar.

On a related note, I've never got around to cleaning up the patch and replying to Robert in the thread on osg-submissions [*]. It looks like your #ifdefs go some way towards addressing Robert's objections. Do you think your working copy could be used for merging the changes and if so, could you reply to Robert in the other thread? I am not sure whether he is reading this thread.

[osg-users] Support for draw_instanced
FYI -- See this same thread in osg-submissions for my recent addition of support for the EXT_draw_instanced extension. As stated in the extension spec at opengl.org, this extension adds two new vertex array drawing commands and a new shader variable gl_InstanceID. The OSG submission exposes the two drawing commands as five new PrimitiveSet types. Adding a shader and referencing the gl_InstanceID is the responsibility of the application. In my work with this extension, I've found it can dramatically reduce cull and draw times. It also reduces GPU time in some particularly bad corner cases. So, the extension is quite useful at increasing efficiency for apps that need to render the same object multiple times.
