Re: [osg-submissions] Support for draw_instanced

[Lionel Lagarde]

Hi, Why you use the EXT version of draw_instanced. This extension has an ARB version. Paul Martz wrote: Hi Robert -- My update and build of OSG went fine, and my draw instanced test programs ported to your implementation smoothly. Thanks again for your help on this great new feature of OSG. Hi to all -- Current svn head of OSG now supports EXT_draw_instanced. Check out the osgdrawinstanced example, which creates a scene graph consisting of a single Geode with a single Geometry with four vertices, but draws several hundred quads at different orientations, positions, and colors.

I disliked having it in the draw() method, but wasn't sure where it should go. Extension checking/function call set up is both a strong and a weak point in the OSG, there are motivations for centralising extension setup and motivations for keeping them local to classes - so the OSG has ended up doing both in different places, sometimes for good reasons, sometime for the wrong reasons... It'd be nice to have a simpler and more manageable scheme that avoids the issues of being pulled in different directions. OpenGL ES and OpenGL 3.x into the mix will further complicate things unless we do come up with a new scheme... I'm updating and building now. I'll let you know if I find any issues.
