Havok 7 Physics testing on Second Life Preview grid

[OpensourceObscure]

@BornForPlay something by Nine Inch Nails from Ghosts_I–IV.

I add songs to my videos via YouTube's SoundSwap feature, which lets you use NIN songs from that album.

[wizziebaldwin]

It's been years since I've been on second life. WOW; how are they doing that? It is like particles? I can't imagine that all of those things bouncing around are primitives that is unless they've done a massive overhaul of the game engine itself.

[OpensourceObscure]

@wizziebaldwin those are simply physic primitives.

This video is more than 1 year old and it shows Havok 7, which is the current physics engine. In a few weeks, there will be another upgrade to the physics engine, which will bring further improvements.

For sure, Second Life keeps improving - even if most of the press still talks about 2007 stuff.

[y0utUBeH8r]

havok 2010, will that be when they release mesh and the new avatar mesh?

[OpensourceObscure]

@y0utUBeH8r as far as I know Linden Lab didn't say anything about that, so Havok2010 and Meshes may get shipped at the same time, or in different moments.

They both are being tested on the Beta grid though, and Havok2010 is only present on a subset of the Meshes sims. So there's definitively a correlation in the development process of these 2 features.

[y0utUBeH8r]

@y0utUBeH8r do you know which sims they are? i have a lot of testing i would like to do there.

[OpensourceObscure]

@y0utUBeH8r correction: initially, it was only a subset of Mesh regions - while 1 month ago, all Mesh regions had gotten Havok2010.

I don't have more up-to-date information right now. You may find more details in the official second life wiki, in Havok_2k10_Beta_Home and Mesh/Mesh_regions pages (can't paste links here).

Feel free to contact me in-world if you can't find them.

[pat12345tee]

Nice video work what kind of video card are you using if i may ask?

[OpensourceObscure]

@pat12345tee Thanks! I own a Nvidia/Zotac GeForce GTX 260 - see above for complete specs and further details.

[dorgenviecj]

Still, it would be awesome if SL would finally implement full clientside prediction

[NasherDezno]

Too bad SL is so laggy, under normal circumstances this would just lock you up until you crashed.

[OpensourceObscure]

@NasherDezno I do this on my sim all the time. Visit LOL, click around over my installation, see yourself.

Still many out-of-date information about Second Life...performances improved under many aspects in the last years.

[bowchee]

please give me the specs of your pc!!!!!!!

[OpensourceObscure]

@bowchee Nvidia/Zotac GeForce GTX 260, CPU i5 660@3.33GHz, 4 gigs RAM. I use the official SL Viewer 2, Development Builds or Kirstens Viewer. I'm running Linux (Ubuntu 10.10) so I'm fully leveraging my hardware (debatable but probably true in my case). Rendering performances may vary on different operating systems.

[bowchee]

@OpensourceObscure thank you much

[MereLee]

this is so mesmerizing o.o

[BlazeBorginSL]

Is this only on the adult Aditi Grid?

[OpensourceObscure]

@BlazeBorginSL no, Havok 7 physics engine was deployed to the Main Grid a few months ago.

by the way, Aditi (the Beta Grid) is mostly made of General/Moderate - not 'Adult' - regions, so every SL user can access it.

if you can't, the official wiki says to change your SL password and wait 24 hours.

[BlazeBorginSL]

@OpensourceObscure Are you sure? I think i was able to go on aditi after changing my passworld before. The thing is i think there's a teen grid aditi and a main grid aditi. I just ended up on two semi complete teen grid regions.

[OpensourceObscure]

@BlazeBorginSL I think what I wrote is correct. No idea about what happened to you.

Anyway Teen Grid is going to disappear in 1 month approx.

[christianf21]

Whats your SL name? Add me please I want to see some of your test work, scripts. My SL ingame name is: christianfeo Bonito

[OpensourceObscure]

@christianf21 I'm Opensource Obscure in SL - I don't really use much the Friendlist tool but feel free to IM or email me (my address is in my SL profile).

Also, you're welcome to visit my space in the LOL region to find free script and full perms objects. The LOL sim is divided in 4 quarters and it will be easy to spot the one I work at ;-)

[Lou500]

This looks fantastic.

[Danrakich]

lol is this Obscure republics youtube O_o?

[jaydavee]

Havok 7 was everywhere for a few days. Now it's all going back to Havok 4. It's a little depressing. I would like for a new Havok to be in and working in SL. Server 1.40.2 gave me one of my darkest days in SL... was ready to refund all my customers and abandon all projects. This is one of the coolest SL videos I've ever seen.

[OpensourceObscure]

@jaydavee a thing I learnt about Second Life is we should always be prepared to change and adapt .. eg change our products, our habits, our use of the viewer ..

Second Life is just the embryo of a new kind of media that is not defined yet; it's an economy where business models are not clear yet; it's a community of communities with very different needs.

[existextinct]

SECOND LIFE IS NOT A MMORPG IT IS AN ONLINE VIRTUAL WORLD CREATED BY ITS USERS IT IS NOT A GAME

[uio3434]

Where can i get script like that lol

[OpensourceObscure]

@uio3434 contact me in-world, it's a quite simple script. Anyway you may need an empty sandbox in order to make it work the same way. On a busy region, it may degrade its performances; if many prims are already present in the sim, you may not be able to rez stuff as fast as shown in the video.

[CorriYammari]

I had tested it too, it still seems bounding boxes are bigger then the mesh itself.

[coren0327]

Exellent video, it looks like PhysX now. I jsut hope that new physics will not broke stuff creators did when using Havok 4, and btw it seems to real collide now, hope its goan be faster physics as the Havok 4 and makes the sims less laggy when using rifles :D

[TrinTrevellion]

Wow!

[kittercat]

Wow, this is an awesome video. I'm so excited for havok7. What do you use to record video? It works really well.

[OpensourceObscure]

@kittercat Thanks! However, I wouldn't expect too much from the first releases of Havok 7 - according to main developer Falcon Linden (who formerly worked at Havok), first iterations *may* slightly improve performances only, and there won't be new physics features (they may come later, though).

I use GLC for recording video - it's an efficient, command-line tool (Linux only). This video was made with the official SL Viewer 2, with shadows enabled and using projected textures as light sources.

[breebw]

Seeing as you have OpenSource in your name come accross to Opensim(OSGrid) and set up your own free regions, and then play with OpenPhysics. Hell, even contribute to the source code.

[OpensourceObscure]

@breebw Thanks for the invite, breebw. I have been playing with Opensimulator since 2007 - I strongly support the project & the concept. I also have a great opinion of the devs team. I had a region running on Cyberlandia grid until few months ago. Unfortunately, last time I tried, performances of physics engines you can use with Opensimulator don't really keep up with the Havok implementation in SL. I'd like to contribute to Opensim code but I can't write in any serious programming language :-\

[breebw]

@OpensourceObscure Yes it is difficult to compete with Havok. They are pretty big now, with many big name dev houses licensing Havok so they can put a lot into improving. But some good news, Games like GTA IV use opensource Bullet X which Opensim can use. SO there is hope.

[existextinct]

@breebw whats the physics engine on opensim?

[breebw]

Have fun doing that in the preview grid, cos you wont be in the main grid. Unless you pay $195 for your own region or you'll exceed the resource limits and get a warning from Linden Labs. Then ban if you keep doing it :(

[OpensourceObscure]

@breebw yeah, and that ban would only make sense, since it's not fair that a single user uses all resources of a server. But I have too much fun doing this kind of things.

That's why I got a private region - I share it with 4 friends...and all visitors are free to do a similar mess!

[Outback371]

Love it , Prims gone in 60 seconds, way to test a sim ! Box boy works well too

[Glemanjun]

Open, sei peggio della BP petroleum a far danni... (parlo del lag, ahahaha)

[RyuDarragh]

@cyborgchimpy: If some adventurous soul wished better performance in SL, they'd have to write a render engine to leverage the video cards full potential and avoid things like "OpenGL" and other performance bottlenecks. Despite having a lowly nVidia 8800GTX/768M card and a duocore 2.1GHz with 3G of DDR2, I can run SL on screen one and then run demos from LightsMark 3D or 3DBench at nearly full speed on screen 2. The power is there, just not leveraged.

[RyuDarragh]

All I can say is "Kick Ass!! That's cool :D"

[MeetTheGrunt]

OMFG :O i love it ;-; so much ;-;

[cyborgchimpy]

how do you keep your framerate that high with those specs? I mean, my graphics card and memory are pretty decent, but I lag like hell with those settings on sl

[OpensourceObscure]

@cyborgchimpy hmm, let's see.... 1) almost no textures to load in this scene 2) no other avatars to display 3) almost nothing at the horizon 4) I'm running Linux so I'm fully leveraging my hardware (debatable but probably true in my case) 5) Linux SL Viewer just performs WELL 6) and here are my specs: Nvidia/Zotac GeForce GTX 260, CPU i5 660@3.33GHz, 4 gigs RAM

[cyborgchimpy]

@OpensourceObscure, oh ok =] ty for giving a complete answer, I wish LL could make sl a bit less memory and graphic card demanding, for having well, a pretty old graphic engine, would have been great if sl could run smooth with the shadow and lighting shading

[kitsune0video]

some questions :3 pc specs? is this part of a official viewer or thirdt party one? i realli liked the shadows with local lights :3 what method of shadows use? geometrical shader like usualyl use all viewers like emerald?

thanks for the vid and good luck!

[OpensourceObscure]

@kitsune0video

1) Nvidia/Zotac GeForce GTX 260, CPU i5 660@3.33GHz, 4 gigs RAM

2) I use the official SL Viewer 2

3) I use all shadow/light features provided by SL Viewer 2, for more information please have a look to my video tutorial "SL Viewer 2 howto: SHADOWS, PROJECTIONS and GLOBAL ILLUMINATION"

4) youtube sucks and won't let me put direct links here so .. less informative reply, sorry.

[kitsune0video]

@OpensourceObscure thanks for the info :3

good pc, im waiting to get one better than mine :P

[cierracat]

Wow!!! Very cool. The collisions are very realistic (instead of bouncing all over the place), and i love how the endless flow of boxes instantly rezzed. Awesome.

[ZeMooz]

Impressive! Cheers for sharing!

[GwynethLlewelyn]

Utterly awesome, OO :)

[sukraMrepuS]

geil!!

[Torley]

I like when the big pink lit cube swipes into the smaller ones, knocking the stream aside.

[Ribunculous]

That looks incredibly fun.

[UnrealDagger]

About time object rendering went client side.

[MrHarold]

@UnrealDagger Yarly.

[NexiiM]

Excellent, looks like it seems much better at handling tons of physical objects.

[DirkTalamasca]

Love it.. Nice video share, OO.

[stikemanon]

Very fun demonstration! Thank you for sharing.

[neotoy]

@OpensourceObscure LOL, sorry, major Freudian slip there. Thought I typed "SOME background info".

[OpensourceObscure]

@neotoy LOL ok! I added some info to video description and I'm going to add some more links later.

Setting up rings and gears would be cool - not sure I can do that - if you know what you're talking about and can help with that, contact me in-world.

[fim71]

Great to see the physics possibilities for Second Life projects.

Well done OpensourceObscure, you rock!

Fim

[neotoy]

Sound background info sure would be nice! Also, while cool, a demo that showed a little more complex interaction would be nice. e.g. interlocking rings, gears, belts, difference in materials. Anyhow, thanks for sharing. Real physics in SL would pretty much be a dream come true for me.

[Nerolus]

A nice bonus to having meshes!
