Collision Handling

چکیده

People are very sensitive to physical events occurring around them... We know that one solid object cannot merge into another; We make decisions about the properties of objects based on the way in which they interact with each other; We judge whether objects are animate or inanimate depending on whether we perceive them as moving of their own volition, or being "caused" to move by another object (referred to as the perception of causality [Mic68]). Many studies have shown that these perceptual mechanisms are established very early on in infancy (e.g. see [BSW85])... but how accurate are they? Research in the realm of physics education has shown that most people have erroneous, yet very robust, pre-conceptions regarding the physical behaviour of objects [Cle82]. This is obviously not a good thing if you are trying to teach introductory mechanics, but it could be very useful if you are trying to get away with fast, yet plausible, physically-based simulations for real-time applications.

Collision Handling for Interactive Garment Simulation

This paper deals with real-time interactive garment simulation, and focuses specifically on collision handling between a character and garments. Because simulation speed must be kept over a certain limit in interactive garment simulation, regardless of the speed or type of a character’s motion, a rapid and stable collision handling method is required. For this reason, we approximate the shape o...

Graceful Degradation of Collision Handling in Physically Based Animation

Interactive simulation is made possible in many applications by simplifying or culling the finer details that would make real-time performance impossible. This paper examines detail simplification in the specific problem of collision handling for rigid body animation. We present an automated method for calculating consistent collision response at different levels of detail. The mechanism works ...

Closest Feature Maps For Time-Critical Collision Handling

In this paper we consider the novel idea of Closest Feature Maps (CFMs) applied to refinable collision response in order to address the potential issues and problems associated with over approximation of contact information for time-critical collision detection schemes that utilise sphere-tree bounding volume hierarchies. Existing solutions to time-critical collision handling can at times suffe...

Collision Handling for Humanoids using Proprioceptive Sensing

High-performance collision handling, is a fundamental robot capability for safe and sensitive operation/interaction in unknown environments, which is divided into the five phases detection, isolation, estimation, classification and reaction. For complex robots, such as humanoids, collision handling is obviously significantly more complex than for classical static manipulators. In particular, th...

Real-Time Cloth Simulation

The field of cloth-modeling has been widely investigated during the last decade. Many solutions have been proposed for the different aspects related to that field, ranging from fast cloth integration methods to complex collision handling. However, it is still challenging to perform simulations in real-time without compromise. In this thesis, we base our work on fast collision detection methods ...
