I don't have access to the beta, so can't test. If anyone does, and also has a machine with nVidia 3DVision, it would be interesting to find out if you can set the nameplates in a stereoscopic fashion.
For example, they higher the threat, the closer the plates appear. If this is possible, break the threat percentage into thirds or quarters, then make each section random within its bounds.
For example, threat 0-33% set a strata of 1-3. 34-66% would be 4-6, and 67-100% threat 7-10. My numbers might be off, and have to do 1-2, 3-4, 5-6 or something like that.
Syncrow, I know about those, but never dabbled with them. I was musing if SetDepth() would work on nameplates. Both Blizzard and AddOn. They probably do, but worth testing?
Might be cool to see when playing or in a video.
And I checked my beta settings. I'm signed up, and have been for a long time. Just no invite. I didn't go through WowI because one of the caveats was having a current WoW subscription, which I don't have. I signed up on WowAce a few weeks ago.
When the 3D support was first added into the game back in Wrath, :GetDepth() et al. did work on nameplates, but it was quickly deemed abusable by addons and blocked from access by Lua (though the 3D spatial rendering should still be visually correct). I don't have the hardware to test 3D with my beta client, but I doubt they've changed the behavior from live, unless by oversight.
