Parallelized rigid body dynamics

John Linford, Teng Moh
2014 Proceedings of the 2014 ACM Southeast Regional Conference on - ACM SE '14  
Parallelized Rigid Body Dynamics by John Calvin Linford Physics engines are collections of API-like software designed for video games, movies and scientific simulations.  ...  However, despite this need for increased speed, it is uncommon to encounter a parallelized physics engine today.  ...  Yet with increasing demand for better utilization of physics in video games, movies and science, a change must come soon to the standard practice used in video games.  ...

‘The parable begins, ‘‘ There was once a rigid body which lay peacefully at rest.  ...  We must naturally conclude that field practice in the game is a necessary adjunct to these pursuits, if for no other pur- pose than that of experimental illustration and test of scientific philos- ophy  ... 

The validity of a rigid body model of a cricket ball-bat impact

David James, David Curtis, Tom Allen, Tom Rippin
2012 Procedia Engineering  
The physical properties of the different bats were measured and used as the input for the rigid body model predictions.  ...  It was found that for impact locations close to the bat's centre of mass, the rigid body model worked well, but some discrepancies were found as the impact location moved away from the centre of mass.  ...  This study validates the rigid body method as a first approximation for the cricket ball-bat impact and opens the door for the method to be used as a tool to explore how changing a bat's physical properties  ...

Structural rigidity in the capsid assembly of cowpea chlorotic mottle virus

B M Hespenheide, D J Jacobs, M F Thorpe
2004 Journal of Physics: Condensed Matter  
FIRST uses the 3D pebble game to determine structural rigidity, and a brief description of this algorithm, as applied to bodybar networks, is given here.  ...  We find that the pentameric substructure, which corresponds to a pentagonal face on the icosahedral surface, provides the best structural properties for nucleating the capsid assembly process, consistent  ...  Acknowledgments We would like to thank Trevor Douglas for introducing us to viral capsids and Walter Whiteley for continuing discussions on the mathematical underpinning of rigidity.  ...

Rigid Body Interaction for Large-Scale Real-Time Water Simulation

Timo Kellomäki
2014 International Journal of Computer Games Technology  
Allowing the water to interact with rigid bodies is essential for applications such as games, but traditional heightfield interaction methods concentrate on water-to-body effects by letting water flow  ...  A drawback of our method is that it has some grid aliasing artifacts that appear especially when the method is used for floating bodies.  ...  The author would also like to thank the editor and anonymous reviewers for their useful comments that helped to improve the quality of this paper.  ...

2013 Proceedings of the 12th ACM SIGGRAPH/Eurographics Symposium on Computer Animation - SCA '13  
Figure 1 : 30 simplified ragdoll fall together into a complex, compact physics world. Abstract Physics-based animation has become a standard feature in modern games.  ...  Typically, the bones in a character's animation rig are each associated with a simulated rigid body, leading to a jointed assembly commonly called a ragdoll.  ...  The rendering for this paper was achieved with Pixie (www.renderpixie.com), which was written by Okan Arikan.  ...
