So, after a good long delay it's finally WebGL demo time again! This one is pretty elaborate, but I feel like it was worth the effort:
WebGL Quake 3 - Q3TOURNEY2
A quick note: I've heard reports that Chrome 5 has trouble with the demo because I'm using the newer texImage2d signature. Your mileage may vary, but if you're having trouble give it a try with the Chrome dev channel.
Now, there are SOOO many things to talk about in regards to this demo: Optimizations, remaining issues, changes made to resources for web use, etc. Unfortunately I don't have the time to elaborate on them right now but I wanted to get the demo out there ASAP to get some feedback on it. Expect another post (or maybe an addendum to this one) within the next couple of days about my thoughts on Quake 3 bsp maps under WebGL.
(UPDATE: My ramblings about the demo are online now)
EDIT: Quick update. I've tweaked the code a little bit to reflect gero3's suggestion of combining the multiple event loops into one. It worked pretty well, and the movement in particular feels better for it (well, not the mouselook. Not much I can do there though). Not to mention the code now reflects a "traditional" game loop much more.
