CAB: Fast Update of aBB Trees for Coil ision Detection Between Articulated Bodies

Collision Detection for Continuously Deforming Bodies

Fast and accurate collision detection between geometric bodies is essential in application areas like virtual reality, animation, simulation, games and robotics. In this work, we address the collision detection problem in applications where deformable bodies are used, which change their overall shape every time step of the simulation. We propose and evaluate suitable bounding volume trees for d...

F-STONE: A Fast Real-Time DDOS Attack Detection Method Using an Improved Historical Memory Management

Distributed Denial of Service (DDoS) is a common attack in recent years that can deplete the bandwidth of victim nodes by flooding packets. Based on the type and quantity of traffic used for the attack and the exploited vulnerability of the target, DDoS attacks are grouped into three categories as Volumetric attacks, Protocol attacks and Application attacks. The volumetric attack, which the pro...

Fast Continuous Collision Detection between Rigid Bodies

This paper introduces a fast continuous collision detection technique for polyhedral rigid bodies. As opposed to most collision detection techniques, the computation of the first contact time between two objects is inherently part of the algorithm. The method can thus robustly prevent objects interpenetrations or collisions misses, even when objects are thin or have large velocities. The method...

Continuous Collision Detection for Adaptive Simulations of Articulated Bodies

We present a novel algorithm to perform continuous collision detection (CCD) for articulated bodies when the motion of bodies is governed by an adaptive dynamics simulation. The algorithm is based on a novel hierarchical set of transforms to represent the kinematics of an articulated body recursively described by an assembly tree. The performance of our CCD algorithm significantly improves as t...
