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.
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.
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
