Building a "Lively™"-style viewer for OpenSim+SL.

So,

I've been working on something for the last day or two (would have got it done faster, but someone demanded I go to bed last night. )

The goal is to produce something you can embed in a web page or website and like the Lively client people can just browse into the world and access a subset of features sufficient to visit it.



If you are interested in the technical specifics, I wrote up two posts on it. Here and here.

I could use some help though - to do accurate primitive rendering, I need to rely on a piece of code LL have been promising to release for a while now.

While I can use the simplified "meshmeriser" we developed to compensate for OpenSim's physics engines - rendering in the viewer is a bit more complex since we need UV coordinates and the meshes to look identical between the viewers, and to get things identical, we need to use the same routines - using the approximations (while more efficient) wont work as well in this case.

There's a Jira issue to get LL to release the bits under a more usable license and I'd really appreciated if people can vote on that one (It's already in the top list of issues, but it's been 6 months since a linden commented on it).

That screenshot looks dead-sexy, Adam.

I'd love to help - but it sounds like what you need is bogged down in Linden Tao-ism.

Sorry!

I will vote and add the jira link in my signature here and over at the official place.

I was just saying in a thread over there that OpenSim is moving at breathtaking speed along with RealXTend and that very soon it will bypass LL. In some ways it already has once implemented.

Thanks for all the work you and the others are doing, Adam.

So is this work going towards a possible way of having a lightweight "portal" into an OpenSim, like a detached avatar able to float around a scene? Maybe some basic interaction?

If so, approximation might be best... for instance, downsampling any textures to very low values (256x256 max, for instance), for performance reasons. I imagine running a full-blown 3d client in a browser would be pretty taxing.

I could be wrong, I'm sadly not a programmer at all

I don't think the performance is going to be significantly (or any) worse just because of how it's embedded. Most of our performance bottlenecks are going to come from hardware.

But downsampling things is easy enough to do.

I was watching a video about WPF 3.5's features just yesterday, really nice proof of concept, Adam. Makes me really wish all these nice features I love so much with .NET were platform-independant :V
