包围盒

First,a maximal encasing box and relative velocity between obstacles and the robot are used to analyze the orientation of collision.

通过分析障碍物最大包围盒在机器人坐标系的位置以及其相对于机器人的速度，得到障碍物与机器人可能发生碰撞的方位，然后使用基于速度改变最小原则和速度改变最佳原则的第一和第二避障策略来完成机器人的动态避障。

Therefore this article introduced the use space surrounding box carries on fast beam tracing on the triangular net model the method, uses this method to be possible fast to complete the up to ten thousand strip beam on the complex model beam tracing, has the very strong practical value.

因此本文介绍了利用空间包围盒在三角网模型上进行快速射线追踪的方法，利用该方法可以在复杂模型上快速完成上万条射线的射线追踪，具有很强的实用价值。

Based on Oriented Boundary Box Tree of point cloud model, a simplified model with topological information is constructed first. Then based on this model representation, a hierarchical segmentation algorithm is implemented.

基于点模型的有向包围盒树，首先建立点模型带拓扑信息的简化模型，基于这种几何表示，将网格模型的层次分片算法推广到点模型中。

The algorithm firstly usd space decomposition method to identify potential regional intersection and then used bounding volume boxes to locate the intersection triangles and the exact points.

该算法首先用空间剖分法找出潜在的相交区域，然后用包围盒求得碰撞的三角面片对和精确的碰撞点。

In order to exploit object-space coherences, the approach can also be combined with popular spatial partition schemes, e.g. bounding box hierarchies and octrees.

为了利用物体在景物空间的相关性，算法可以结合层次包围盒、八叉树等常见的场景划分方法。

In this paper, we choose 2D stripe model to modeling hair, and using a set of ellipsoids to approximate the bounds of all the external objects, made the complexity of collision detection independent of the complexity of objects.

在此选择使用二维发带对头发进行建模。引入椭球体包围盒进行发丝和人体及其他物体之间的碰撞检测，使得计算复杂性与人体的复杂性无关。

A time-bound box based consistency maintenance algorithm is proposed.

本文提出了基于时间包围盒的一致性控制技术。
