This work reviews the main techniques to model dynamical systems with contact-impact
events. Regularized and non-smooth formulations are considered, wherein the fundamental …

In a geometric context, a collision or proximity query reports information about the relative
configuration or placement of two objects. Some of the common examples of such queries …

Clothing computer design systems include three integrated parts: garment pattern design in
2D/3D, virtual try-on and realistic clothing simulation. Some important results have been …

The calculation of the minimum distance between surfaces plays an important role in
computational mechanics, namely, in the study of constrained multibody systems where …

Most of the existing point-to-mesh distance query solvers, such as Proximity Query Package
(PQP), Embree and Fast Closest Point Query (FCPW), are based on bounding volume …

Motion capture is often retargeted to new, and sometimes drastically different, characters.
When the characters take on realistic human shapes, however, we become more sensitive …

Arrangements of geometric objects refer to the spatial partitions formed by the objects, and
they serve as an underlining structure of motion design, analysis, and planning in …

We introduce a bounding volume hierarchy based on the Slab Cut Ball. This novel type of
enclosing shape provides an attractive balance between tightness of fit, cost of overlap …

In this doctoral thesis, we study the problem of computing the ball of smallest radius
enclosing a given set of points in any number of dimensions. Variations of this problem arise …

为了快速处理织物与模型的碰撞以获得仿真结果, 提出一种基于自适应椭球包围盒的碰撞检测
方法. 该方法以法向距离和径向距离的加权**均值作为表面误差, 数值化表示椭球与模型之间的 …
