SIGGRAPH 2011 course, Bullet 2.78 out, job opening

We are organizing a course on destruction and dynamics for game and film production for the SIGGRAPH 2011 conference in Vancouver. It will be held on Sunday August 7 from 2-5.15PM. Aside from this we released Bullet 2.78 a while ago. This release adds the option for contact generation between convex polyhedra using contact clipping and a fracture demo among others. Last but not least, AMD is looking for developers who want to help out with physics simulation, see the job description here.

Fast Multiphysics for Softimage uses Bullet (Exocortex Momentum 2.0)

Exocortex is pleased to announce that Momentum 2.0, the ultimate high speed multiphysics simulator, is now immediately available for Autodesk Softimage 2010, 2011 and 2012.

Exocortex Momentum 2.0, because it relies on the industrial strength Bullet physics framework, provides robust support for Rigid Bodies, Soft Bodies, Cloth, Ropes, Constraints, Interactions and Attachments.

Bullet at GDC 2011 Physics Tutorial, Double Fine ‘Stacking’

The presentation is titled ‘game physics artifacts’ and covers similar material to chapter 2 of the Game Physics Pearls book. We will use both Bullet and the new Sony Physics Effects SDK to illustrate some examples. You can download the presentation for the Game Developers Conference Physics Tutorial and the preliminary Physics Effects-Bullet integration from

Also, you should check out the new Double Fine Studios Stacking game on XBox Live and PSN.

Happy 2011: 3DMark 11 uses Bullet Physics, FXGuide Interview

The latest Futuremark 3DMark 11 uses Bullet Physics in both CPU and GPU benchmarks using Microsoft DirectCompute. For more info see this whitepaper.

Check out this recent interview with Coumans recently started at Advanced Micro Devices (AMD), having worked at Sony Computer Entertainment in R&D. “At AMD I will continue and expand the work I started at Sony on the open source Bullet physics library.”

Hydro Thunder Hurricane for XBox 360 Live Arcade using Bullet

The Postmortem on Hydro Thunder Hurricane on mentioned the use of Bullet Physics for their game:

“I should mention also that we didn’t build everything ourselves: We used FMOD for audio, Bullet for collisions and rigid body physics, and the truly wonderful Subversion (specifically TortoiseSVN) for version control.”

Thanks to Colin Barrett for reporting this news.

PDI Dreamworks Megamind, Shrek 4 and ‘How to train your dragon’ are using Bullet

We learned that Megamind, Shrek 4 and How to train your dragon are using Bullet physics for rigid body simulation. For Megamind, PDI build their own destruction system on top of the Bullet solver. Megamind is out in the cinemas on November 5th.

Cinema 4D 12 Dynamics using Bullet adds constraints, springs, soft body and .bullet export

From the Maxon website, the latest Cinema 4D release 12 adds improved Bullet Dynamics support:

“Drop everything and let the laws of physics take over with the new rigid body dynamics in CINEMA 4D Studio. Based on the production-proven Bullet engine, the dynamic simulations are rock-solid stable and simple to use. Simulations can include thousands of objects and millions of polygons. Just add a tag to any object and let the forces of nature take over. Collisions can be detected for any shape – even concave surfaces. Hierarchies can be treated as a single object or individual dynamic bodies.

With just a click of the mouse, your hard bodies transform into soft and springy structures. Soft body simulations in CINEMA 4D Studio are simple to setup and offer amazing flexibility. You can easily adjust how soft and springy each object should behave, using vertex maps for point-level control.”

Download a demo version that supports all those features including .bullet export here:

Bullet in SIGGRAPH collision detection course, Toy Story 3 game, Sherlock Holmes and A-Team movie

On Monday July 25th, 2-5PM at the SIGGRAPH conference in Los Angeles we  discussed recent improvements in the Bullet collision detection pipeline in our SIGGRAPH course “Recent Advances in Real-Time Collision and Proximity Computations for Games and Simulations“. Thanks for all questions and feedback! See the slides here.

Disney Avalanche just shipped their Toy Story 3 game for PlayStation 3, XBox 360 and Wii, and it uses Bullet physics.

Weta Digital integrated Bullet in their in-house FX pipeline tool called wmRigid, and one of the first releases using the rigid body simulation is the A-Team movie, thanks to Ronnie for letting us know!

“I work at Framestore, and spent several months last year developing a tool called “fBounce”, which allows artists to run Bullet rigid body simulations through Maya. The tool has been used on a few productions now, but the only one released so far is Sherlock Holmes, which won the VES award for Outstanding Supporting Visual Effects in a Feature Motion Picture. There’s an article on the fxguide website about the effects, which mentions fBounce twice!”

Thanks a lot Kate for sharing this information. See the original posting here.

Plans have changed (was AMD is giving away GPU physics tools with DMM2 and Bullet)

August 2011 update: Plans have changed, a free version of the DMM plugin is part of Autodesk Maya 2012.

Bullet 2.76 out, new binary .bullet file format with Maya and Blender authoring tool support


The new Bullet 2.76 SDK includes several new features and improvements. The new btInternalEdgeUtility avoid collisions against internal edges for smooth sliding along a triangle mesh. The cross-platform cmake build system support is improved and preparations are made towards upcoming OpenCL GPU acceleration for Bullet 3.x.

The new binary file format improves current and future tools support for Bullet.

The extensible .bullet file serialization is cross-compatible between 32/64bit, little and big endian, single and double precision and different Bullet SDK versions.  This means you can export a .bullet file in Maya 64bit on a little endian Intel machine and import it on a 32bit big endian PlayStation 3.

2012 uses Bullet

Digital Domain and Sony Pictures used Bullet Physics Simulation for a lot of the rigid body special effects in the movie 2012. and CG Society have more details about the special FX in this movie, or you can check out the upcoming Issue 120 of Cinefex. Apart from the Maya Bullet Dynamica plugin, Cinema 4D 11.5 Bullet integration into MoDynamics and Blender 3D Bullet integration there is now a new open source Houdini plugin for Bullet rigid body simulation available. Special thanks to Nafees Bin Zafar!
