Real-Time Collision Detection Mpegs
Based on Hierarchical Incremental Computation
Collision detection is a fundamental problem in computer animation, computer graphics, physically-based modeling, and robotics. For applications and simulations in these domains to be convincing, they need to not only render realistic images, but also precisely model object interactions in the simulated environments.
We present several animations employing our collision detection work. The original sequences were generated at NTSC resolution and ran somewhere between 10 and 30 frames per second (i.e. "real time"). The performance you see when playing them back is clearly unrelated to their run-time performance.
This shows a real-time multi-body simulation of 300 objects of about 60 faces each colliding in a dense environment. The objects turn red when struck and bounce off each other. You can run the actual simulation using our free software.
