Typical vehicle simulations require numerical integration at an integration time step no larger than 0.01 seconds, usually less than half that time. This does not leave enough time to carry out the complex calculations required for detailed collision calculations in real time. This paper presents a method that strikes a compromise, which, although not carrying all the detail necessary for very ...

Soft-body models are common in games to simulate cloth or elastic objects. To realistically simulate soft-body objects, collision detection and response is required. In addition, soft-body models must re-arrange their internal structure to react to the collision. This paper presents a new collision detection and response algorithm which can simulate a variety of soft-body material behaviors ran...

In the animation of deformable objects, collision detection and response are crucial for the performance. Furthermore, a physically correct cloth simulation requires robust collision avoidance, since any overlapping is visible and often results in expensive correction procedures. Much progress has been achieved in improving the numerical solution, and therefore most animations employ large time...

A novel OSH collision detection method based on SDM is presented and performed. Tescher present collision detection based on OSH, this algorithm has been used in many situations about mapping couple for validity. But Tescher used a barycenter coordinate weight value to detect collision, it limited collision responds that this algorithm can't measure depth and normal of contact. We present a met...

Before unmanned aircraft can fly safely in civil airspace, robust airborne collision avoidance systems must be developed. Instead of hand-crafting a collision avoidance algorithm for every combination of sensor and aircraft configuration, this project investigates the automatic generation of collision avoidance logic given models of aircraft dynamics, sensor performance, and intruder behavior. ...

This paper focuses on a study of the sequential action execution module for a collision avoidance system in ocean navigation. The overall decision-action process of collision avoidance consists on a Fuzzy logic based parallel decision making module and those decisions are formulated into collision avoidance actions by a Bayesian network based sequential action execution module. The presented co...

So far, two different 2-block collision differentials, both with 3-bit input differences for MD5, have been found by Wang etc in 2005 and Xie etc in 2008 respectively, and those differentials have been improved later on to generate a collision respectively within around one minute and half an hour on a desktop PC. Are there more collision differentials for MD5? Can a more efficient algorithm be...

In this paper an approach for handling collision within the Modelica MultiBody library is presented. Therefore, a short overview about collision consideration for multibody simulation is given. Different methods for calculating the contact reactions are discussed and their potentials for implementation in a free Modelica library are deliberated. Furthermore the implementation of this collision ...

We propose an efficient method for hair animation. The motion of hairs is modeled by a simplified physical simulation. Collision between hair and a human body or other objects is used to make a realistic hair animation. Fast collision detection is required because the number of hairs is very large. Therefore, a cylindrical representation of human body or other objects is created for efficient c...

Anti-collision algorithms are very important to solve the anti-collision problem in multi-tag and multi-reader environment. The anti-collision algorithm is divided into the anti-collision algorithm for multiple tags and the anti-collision algorithms for multiple readers. The anticollision algorithms for multiple tags are largely divided into tree-based deterministic algorithms and slot aloha-ba...
