what is this?
http://eventful.com/users/lindenlab

here you can buy "play" shares of Linden Lab:
http://www.alexadex.com/ad/url/lindenlab.com

this company apparently developed the 3D engine for SL:
http://www.realityprime.com/portfolio.php
they also developed GOOGLE EARTH. Is Linden Lab still working with this company?

Presumably Linden Research is using eventful.com as a calander system for it's internal scheduling, or else it is a user because the secondlife events calendar is stored there.

http://eventful.com/groups/G0-001-000006232-8 will get you to the SL events list.

It's much more useful than the inworld events list.

You can filter out things, like -slingo gets rid of the slingo from the list.

Neat! I doubt it. Interesting to know that SL's 3D engine was NOT originally developed by LL! Too bad, too, since LL can't seem to fix SL's supposed "simplified radiosity" and, instead, needs to rewrite the lighting model. :/ But, then again, for RealityPrime to NOT make it hardware-accelerated in the first place is pretty stupid...

What "optimized visibility culling"? You mean how SL only renders terrain out to an arc in the camera's immediate view? I find it interesting since I had a similar improvement for Active Worlds before SL was developed...:

From: someone

3D Engine

visibility

1. alternate rendering: Instead of using the object's center to figure out whether to display it or not, based on the visibility distance setting, why not use the object's bounding box? That way if the object's bounding box is within the visibility distance, the entire object is displayed, instead of leaving gaps and then having objects blip in and out of view. I think that would make things smoother and more fluid.

Also, if objects come into view first only within the actual 3D pane, and then the rest of the complete visibility radius, this would also speed up things. Plus it might allow AW to render more objects into the scene while moving instead of only up to 25m like it does now.

Unfortunately, SL's implementation needs some slight tweaking so it finishes downloading the scene when SL is idle.

Seems interesting SL has a LOT of things on this list...

For the Record

The work on SL's 3D engine you linked to was done in-house (at SL headquarters). They do their own 3D development and I came in to help out for about a year before their launch. Some of the projects I worked on were supplanted by better 3rd party systems (like for visibility), some are nice but slow, and some are still in general use. There is no relationship between SL and Google Earth (that I know of).

As for "no hardware acceleration," that shouldn't be the case, however rendering so many discrete objects can be a performance hog. Most of the work involved making the engine more optimized.

But I'm sure the next engine revision will be much better. I no longer have any inside information, and what I just said is probably the limit of what I can say given the NDA relationship.
