Collision Detection


Crowley Davis Research, Inc. has been under contract with the Department of Defense since 2002 to research and develop new biomedical simulation technologies. In the course of this work, we found that simulations were slowed by the computational strain of detecting collisions.

The Company has developed a collision detection method that accelerates performance and improves computer memory use compared to state-of-the-art commercial quality physics engines such as Havok and Nvidia’s PhysX. We have begun filing patents on this collision detection technology and its utility for simulation, graphics and physics engines, and visual special effects.

For animated depictions of dynamic and irregular shapes such as breaking glass, fluid flow, or growth of living cells or tissue, particle simulations involving thousands or millions of particles (usually drawn as points or spheres) may be needed to achieve the desired resolution. But this is expensive: for animations involving more than several hundred particles these calculations can account for more than half of the computer rendering cost, because each particle’s path and its potential collision with each of the other particles must be resolved in every frame.

Where conventional methods now takes days to render, our new collision detection may shorten that time by 50% or more, dramatically reducing the costs to produce high quality animation. Improved collision detection can enhance a wide array of applications including game element interaction (for instance, individuals in a massively-multiplayer online game) or resource demand in mobile phone apps.
