Kinetic Separation Lists for Continuous Collision Detection of Deformable Objects
نویسندگان
چکیده
We present a new acceleration scheme for continuous collision detection of objects under arbitrary deformations. Both pairwise and self collision detection are presented. This scheme is facilitated by a new acceleration data structure, the kinetic separation list. The event-based approach of our kinetic separation list enables us to transform the continuous problem into a discrete one. Thus, the number of updates of the bounding volume hierarchies as well as the number of bounding volume checks can be reduced significantly. We performed a comparison of our kinetic approaches with the classical swept volume algorithm. The results show that our algorithm performs up to fifty times faster in practically relevant scenarios.

Kinetic Bounding Volume Hierarchies for Collision Detection of Deformable Objects
We present novel algorithms for updating bounding volume hierarchies of objects undergoing arbitrary deformations. Therefore, we introduce two new data structures, the kinetic AABB tree and the kinetic BoxTree. The event-based approach of the kinetic data structures framework enables us to show that our algorithms are optimal in the number of updates. Moreover, we show a lower bound for the tot...
متن کاملCollision Detection for Deformable Objects
Interactive environments for dynamically deforming objects play an important role in surgery simulation and entertainment technology. These environments require fast deformable models and very efficient collision handling techniques. While collision detection for rigid bodies is well-investigated, collision detection for deformable objects introduces additional challenging problems. This paper ...
متن کاملA Collision Detection Framework for Deformable Objects
Many collision detection methods have been proposed. Most of them can only be applied to rigid objects. In general, these methods precompute some geometric information of each object, such as bounding boxes, to be used for run-time collision detection. However, if the object deforms, the precomputed information may not be valid anymore and hence needs to be recomputed in every frame while the o...

Topics of physically based modeling of deformable objects and collision detection have been extensively researched. Please refer to [1, 2, 3] for recent surveys. Nowadays, the combination of GPU techniques and multiresolution physical models [4] allows interactive simulations of complex deformable objects with a large number of polygons. To achieve this, the geometry of the object is separated ...
متن کاملBucketTree: Improving Collision Detection Between Deformable Objects
In recent years, thanks to the increasing computational power available, real time computer animation has naturally evolved to model more complex and computationally expensive scenes. Consequently, all the problems concerning physical modelling need further research to tackle these new requirements, especially the problem of collision detection for deformable objects. Most existing solutions ca...
