shatter help

If I knew how to mod it i totally would, but alas that’s not gonna happen. LoL. Oh well, back to PhysX for me.

I’d be impressed if Bullet was properly ported to OS X. The 2008 plug-in was flakey and very alpha. My friend who’s no stranger to XCode compiled the Bullet plug-in for Maya 2009 OS X but it didn’t work. I think that the nParticles and newish dynamics stuff likely means it’s not a straightforward recompile.

Not sure if this helps but the BonusTools come with the measure.mll which when loaded will add a couple new measure types to the Create->Measure Tools menu. The one that might be of help is “volume” which can be queried in mel using “measure -v -ver pCube1”; I have no idea what other useful flags it may have.

Cheers,
Pete

I would really like to get his xcode project file if that’s possible. Getting the linking sorted is driving me nuts.
Dave.

Great, sounds good, I hadn’t noticed. measure -v; does appear to do the trick. I don’t see a doc either, but it appears the params are: -separate (-sep) : one value per object, if multiple, otherwise total; -verbose (-ver); -surface (-s) : …area, similar to polyEvaluate -a; -volume (-v).

Thanks for pointing that out!

Hi all, I’ve compiled the bullet plug for osx maya 2009.

have a look at my post here:
bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=12&t=3856&p=14417#p14417

there may be issues, I’ve not tried it yet myself, but if your on a mac with maya 2009, this is a later version of the code than the previous binaries. Make sure you report your findings over at the bullet forums.

Dave.

wow - thanks. Although, I ran the test scenes and I think there are some problems. The field ones seem to work (although much slower than I’m accustomed to with the Bullet demos my buddy Shamyl compiled here - original thread). The peanut box and others that involve collisions don’t work - there are no rigid body interactions so the peanuts and spheres just sail through the objects. here’s the error output from the peanut box:

// Error: line 1: Plug-in, "dynamica.bundle", was not found on MAYA_PLUG_IN_PATH. //

The peanut funnel doesn’t show any peanuts - just a falling funnel. The 2008 plug-in wasn’t stable but I remember it did get the RB collisions to work.

hmm, well first thing I notice is the plug is not called dynamica.bundle when I compiled it. You could try changing the name, see if that helps. As for the attribute names, that demands a closer look. Have a go at making a scene from scratch…

Dave.

Hey Sphere, if your watching, I wonder if you could share one of your scenes using the bullet plug? The concrete wall would be great, I’d just like to check parity with the mac version. Also did you compile from source, or use one of the provided binaries? I used 2.75rc6 for this one.

Cheers
Dave.

ya, that doesn’t work either. I create a sphere active RB and then try and attach a passive rigid body to a mesh cube and when I animate, I get two spheres splitting from the same spot. Any RBs I try and create just make spheres

Should I post here or on the Bullet forum? I registered.

changing the plug-in name, relaunching Maya and reloading didn’t help. But like I said, the 2008 plug-in didn’t completely work so the problem is likely deeper than just a good recompile.

probably best to keep this over at the physics forum, the experts are there, and there may be contributions from other people unaware of this thread hopefully.

k - will do that.

Yeah, ok, actually I’ll write some Dynamica utility scripts tonight and a quick blurb on how to use them and with the Voronoi shatter… Hold on, I’ll post back tonight once I’m done and uploaded… (hopefully I don’t stumble on a tiny bit of MEL :))

I compiled the source, rev. 1706, I think, but it should be pretty much identical to what’s in the 2.75rc6 package, especially when it comes to Dynamica (Bullet for Maya Plugin).

Thanks Sphere.

Mac users, I’ve recompiled the plugin, please have a look here:

http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=12&t=3856&p=14419#p14419

I’m determined to get this going, so please try it. Post your experiences on the bullet forum.

I hope this one flies OK as I have to go away for a few days… be great to see a mac animation or two:)

Dave.

Hey davegreenwood. I 'm on an old PPC running Maya 2008. Is there a compatible version for my specs?

I’m not sure if the 2008 binary is universal… try it out:

Actually, it says it’s Intel…

Ok, I’ve put something up on the Bullet Physics web site, at the end of this thread: RBD Tools for Dynamica (Bullet for Maya) = utils, bake, etc.

Thanks Sphere, trying them out now…

Dave

thank you all
how do i find first version of destructor? , in latest version it uses nparticles rather than normal particles. i really need first one.

thank you guys again ,
