Avination donates physics code to OpenSim

Avination, a commercial grid running on the OpenSim software, announced the donation of 800 lines of physics code today, which will help OpenSim users simulate bouncing balls, reindeer pulling sleds, and feathers lightly floating down through the air.

The code was pushed to the OpenSimulator core repository on Friday, the company said. It includes support for such physics parameters as Shape Type, Density, Friction, Bounce and Gravity.

The code can also be used with the new Bullet physics engine, currently being developed by Intel.

“Avination will continue its policy of donating code to the open source project so stay tuned for more,” the company said in a press release.

Physics is one area in which OpenSim has been lagging behind Second Life, which uses the proprietary Havok physics engine. By default, OpenSim uses the free, open source ODE physics engine until Bullet is complete.

A better physics engine will allow for more realistic behavior by in-world objects, as well as better vehicles.

Avination’s major commercial competitor, InWorldz, has recently rolled out its own physics alternative, PhysX.

    wow! phenomenal contribution! thank you Avination! this speaks volumes to your role in the community =)

    I’m pretty speechless -with this contribution Avination is helping OpenSim match feature parity -and eventually overtake- Secondlife. The whole community is very greatful for this contribution! o/

    We have some pretty damn impressive physics on Aurora-Sim , I and nother resident pushed out some video’s of what you can expect from Aurora-Sim(http://www.youtube.com/watch?v=_i42KIzrrq0 and http://www.youtube.com/watch?v=KtgWlqp6nCc) , and vehicles, our work pretty damn smooth their too, you can see that video here: http://www.youtube.com/watch?v=z1B948PpIkU (I learned not to use OSSL car scripts gotta use LSL ones because well aurora devs used the hooks SL used not the ones Opensim used)

    I do like avinations physics contributions quite a lot. I was there yesterday with Judy @ her Hobo Park and her eeeeek [yes, it is 5 e’s and if you misspell it she will go all bonkers on ya!!–i joke, of course] ride was by far the smoothest than in ANY other grid I have tried it on.

    And just my usual reality check here, inwz physx thing is not fully implemented yet, and who really knows how good it will actually be if, or when, that happens…jus’ sayin’-))

    Sounds good, look forward to this

    This is wonderful. I have been hoping that they would do this. It sure does make their reputation more positive …. at least with me. Way to go Avination!

    yes i as aurora player entertainer tester whatever like this phisics o and i see opensim have also a good product i say give it allone the time for a shotgun

    That is great news! Thank you Avinations!

    Glad to read about this, for sure Open sims need a physics engine!
    But I dont feel the need to gain at the cost of SL, LL is doing a great job in dong that by themselves and the less open sims community try to emulate SL the better!

    Let me just say this …I have two names on these grids for my own reasons …I am Judy Muircastle on sl and Avination grid and patti mallory on iwz and osgrid…I have been building amusement park rides on sl for almost 5 years now and also all types of vehicles …so yes I know physics well !! When I hit the avination grid to open Hobo Amusement park ..the largest and highest traffic on sl ….I could not believe the physics on Avination its totally amazing. I used a 31 prim limit physics vehicle script from sl for a friends wedding carriage of 171 prims….and to my absolute surprise it worked !! my rides from sl work better there my vehicles from sl work better there….I have been on most other grids and nothing can touch avinations physics !! no way !! If you use physics a lot you have to go try it you won’t believe it I assure you ….say what you want …but the proof is in the puddin’ lol

    oh, and you’re right mine, The eeeeek has 5 e’s haha !!

    Testing on 7.4 with modified scripts here is a teaser from day 1. http://www.youtube.com/watch?v=2ln15Yz3xgE&feature=youtu.be

    Video is a bit iffy being it was recorded via Skype shared screen
