Dedicated short-range communication (DSRC) has been used in prototyped vehicles to test vehicle-to-vehicle communication for collision avoidance. However, there is little study on how collision avoidance software should behave to best mitigate accident collisions. In this paper, we analyse the timing of events and how they influence software-based collision avoidance strategies. We have found t...

Collision handling is a comparatively timeconsuming task in dynamic simulations and the computational efficiency of collision handling techniques can vary significantly dependent on the spatial configuration of the environment. These issues have to be addressed in interactive simulations such as games or surgical simulators, where a pre-defined response time should be guaranteed for each simula...

Collision detection and response is an important but costly component of computer animation. We identify three basic reasons why collision-detection algorithms can be slow. We present a new collision-detection algorithm that directly addresses two of these problems and that prepares us for future work on the third. Our algorithm is based on a four-dimensional structure that puts a conservative ...

We present a method for efficiently simulating minor deformations that result from collisions. Our method alters only bump maps and leaves mesh geometry unchanged. It is well suited to games because although the results are not physically correct, they are plausible and are computed in real-time. In a real-time simulation the CPU already carries a high load due to game logic, I/O, and physical ...

Bringing about desirable collisions (making interceptions) and avoiding unwanted collisions are critically important sensorimotor skills, which appear to require us to estimate the time remaining before collision occurs (time-to-collision). Until recently the theoretical approach to understanding time-to-collision estimation has been dominated by the tau-hypothesis, which has its origins in J.J...

This paper addresses the problem of estimating time to collision from local motion eld measurements in the case of unconstrained relative rigid motion and surface orientation. It is rst observed that, as long as time to collision is regarded as a scaled depth, the above problem does not admit a solution unless a narrow camera eld of view is assumed. By a careful generalization of the time to co...
