Hello everybody,<br>Please forgive me if this information is stated somewhere else, but I can't find a "correct" way to cite Bullet Physics in an academic paper.

Hi All,<br><br>I've recently published a textbook with Springer-Verlag entitled "Guide to Dynamic Simulations of Rigid Bodies and Particle Systems" (ISBN 978-1-4471-4416-8). This book is a significant re-write of the one I published about 11 years ago also with Springer, namely "Dynamic Simulations of Multibody Systems" (ISBN 0-387-95192-X).<br><br>Topics and features of this new book include:<br>- Examines the problem of computing an hierarchical representation of the geometric description of each simulated object, as well as the simulated world<br>- Discusses the use of discrete and continuous collision detection to handle thin or fast-moving objects, including a derivation of the conservative time advancement algorithm<br>- Describes the computational techniques needed for determining all impulsive and contact forces between bodies with multiple simultaneous collisions and contacts<br>- Covers articulated rigid bodies and the derivation of the dynamics equations for spherical, universal, revolute, cylindrical, prismatic and rigid joint systems<br>- Concludes each chapter with exercises, ranging from issues of algorithm enhancements to alternative approaches that complement the algorithms discussed in the book<br><br>The complete table of contents can be accessed through Amazon. <br><br>Best wishes,<br>Murilo<p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=9656">murilo101</a> — Tue Nov 06, 2012 11:18 pm</p><hr />

Brian Mirtich's thesis has a small mistake in it. I wrote a corrected version of his collision response algorithm here:<br><a href="http://www.euclideanspace.com/physics/dynamics/collision/practical/RahilBaberCorrectionToBrianMirtich.pdf" class="postlink">http://www.euclideanspace.com/physics/d ... irtich.pdf</a><br>There's also some code demonstrating the (quick) 2d version of the algorithm:<br><a href="http://www.euclideanspace.com/physics/dynamics/collision/practical/Simple2DCollisionsWithFriction.c" class="postlink">http://www.euclideanspace.com/physics/d ... Friction.c</a><br>The 3d version of the algorithm is slower as it involves numeric integration but if you're clever about how you discretize the space you can make it into a constant time algorithm.<p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=8133">rahilbaber</a> — Sun May 08, 2011 12:59 pm</p><hr />

Hi new guy here, <br><br>could anyone suggest which engine would be good for projectile motion, and collision detection, I am currently hoping to develop a indie PC game that uses a projectile motion to launch objects (arrows) at a target. I'm just doing a bit of research to find out which direction I should head in. <br><br>Thanks<p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=7894">ExponentialP</a> — Thu Mar 10, 2011 5:50 pm</p><hr />

You might want to add "AgX Multiphysics" from Algoryx to the list of engines (and remove<br>this post). It is proprietary/commercial but licensed with source code to customers.<br>Since it is rather modular, and is likely to become even more modular, we<br>consider making several modules open source in the future, but right<br>now we have hands full of customer related projects.<br><br>Most likely, academic discounts will be substantial and might also include<br>a source license. We're still discussing the details...<br><br>AgX is not a game physics engine (there are almost too many of those, including some really<br>good ones under open source licenses e.g. *Bullet*!), but intended almost entirely for the professional<br>market (simulators, CAD,  engineering, science, automation/robotics, medical sim, etc).<br>However, it can be tweaked to behave pretty much like a game engine too, by choosing e.g. a<br>simple friction model, a gauss-seidel solver, few iterations, time coherence, freezing, damping etc.<br><br><a href="http://www.algoryx.se/" class="postlink">http://www.algoryx.se/</a><p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=1339">KenB</a> — Mon Apr 28, 2008 5:22 pm</p><hr />
