Cool. If you're working on top of the core render pipeline classes
(LLDrawPool, LLViewerObject, LLDrawable, LLPipeline), you'll want to
build against first look, as there are significant architectural changes
to the renderer. If you're just doing everything at the window creation
level, that code hasn't changed. The work from first look will be
merged down into the main distribution when it's done.
As for the HUD objects, the render path for those objects has been
completely removed and rewritten from scratch in FL. They now use the
same pipeline as the rest of the world, but use a custom camera
transform. If you check out the FL client, you'll want to look in
LLViewerDisplay.cpp setup_hud_matrices. Fenagling that matrix should do
what you want.
After you submit the patch set, send me an e-mail and I'll look at
integrating it. What stereo hardware would you recommend for testing?
