“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.
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.
“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.”

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.
August 2011 update: Plans have changed, a free version of the DMM plugin is part of Autodesk Maya 2012.
See the obsolete press release at http://www.amd.com/us/press-releases/Pages/amd-ecosystem-2010mar8.aspx
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.
For download of Bullet, the new Maya Dynamica plugin and further information see http://bulletphysics.org/Bullet/phpBB3/viewtopic.php?f=18&t=4779
January 12th marks the official release date of the PC kart game Zero Gear by NimbleBit! For the low price of only $19.99 you can beat up your friends in 18 different levels, in customizable karts and characters. Play with physically based weapons, earn achievements and compete in many different game modes.
It uses Bullet for its physics and Ogre 3D for graphics rendering.
Go fishing for gifts!
Play either one of the 4 characters of Cocoto’s world and go fishing for treasures in one of the 4 magical environments of this famous series: Abyss, Atlantis, Jungle and Heaven. Watch out, each world will have its own challenges and gifts!
Jay Roth President, 3D Product Division at NewTek. 2009-12-08. “DYNAMICS: Functionality based on the popular Open Source Bullet Physics Library, one of the best physics libraries on the market today.
Digital Domain and Sony Pictures used Bullet Physics Simulation for a lot of the rigid body special effects in the movie 2012. DigitalContentProcucer.com 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!
Kester reports that Madagascar Kartz uses Bullet and an improved version of its btRaycastVehicle in their upcoming 4-player splitscreen racing game. He also shares some experiences on how to improve the vehicle simulation. The Dreamworks franchise is published by Activition and is available from October 27th for all game consoles. Check out the YouTube video.
“We are also using a modified version of an open source physics engine called Bullet Physics Library to calculate our physics simulation and collision inside the game. We have in-house optimized it for the Xbox 360 CPU and vector units. Our game engine is designed to be fully multithreaded, and we are simulating physics at the same time we are processing game logic, graphics, sound and particles in other Xbox 360 hardware threads. With extensive optimization, we have achieved a very good balance, with all six CPU hardware threads constantly working under heavy load.”
The August 2009 issue of Game Developers Magazine features an article about game middleware, written by Mark Deloura. They surveyed over 100 senior developers of various development houses, mainly working on PC, PlayStation 3 or XBox 360.
According to the article, developers like having access to the full source code. When purchasing a Havok or PhysX license, some of the core algorithmic implementations, such as the core constraint solver or collision detection internals are not exposed. PhysX is rated number 1 at 26.8%, Havok comes 2nd at 22.7%, Bullet third at 10.3% and Open Dynamics Engine fourth at 4.1%.
You can purchase an electronic version of this issue for $3.95 here.
“We use it for our character controller (our own custom one), line of sight checks, and so forth as well as for vehicle physics in the Racing and Demolition Derby instances.”
We have been working for a while on parallel physics optimizations for various platforms. As part of the Math and Physics Tutorial on Tuesday March 24th, Takahiro Harada and Erwin Coumans will do a joint presentation that discusses our experiences how to optimize a rigid body physics pipeline for CUDA, SPU, Larrabee and OpenCL.
