First,the paper introduces the method to compute OBB,the theory of OBB intersect test,and the common process for the construction of OBB bounding boxes hierarchy.

首先介绍了OBB包围盒的计算方法、相交测试原理，以及OBB层次包围盒构造的一般过程。

Research work has been done as follows:(1) Based on the full research of inherent characters of OBB hierarchical box, this thesis implements a series of key techniques such as building OBB and OBB tree, and overlap test between OBB boxes, verifies the attribute that OBB has the advantage that it is fit for the collision detection between rigid bodies and optimizes the shortcomings and disadvantages of OBB.

主要从事了以下几个方面的工作：(1)在研究OBB等层次包围盒固有特性的基础上，通过具体实现构建OBB和OBB树、包围盒间重叠测试等技术，比较了OBB适用于复杂环境中刚体碰撞检测的优势，并针对OBB存在的缺点和不足加以优化。

Based on the limitations of OBB, this thesis proposes an optimizing overlap test algorithm of bounding box and primitive. This method eliminates the bounding boxes of leaf nodes and streamlines the OBB hierarchical layer. This method also introduces a separating axis theory in the overlapping test between the primitives in order to accelerate the velocity.

针对基于OBB碰撞检测算法存在的缺陷，研究利用包围盒与基本几何元素相交测试的优化方法，消除叶子结点包围盒，精简OBB层次结构；同时在基本几何元素相交测试中引入类似分离轴的方法，加快检测速度。

The temperature at the vertices can be utilized to determine whether an isothermal line goes through the sub-area or not.The sub-areas that an isothermal line goes through will be gradually subdivided into smaller and smaller sub-areas until the sizes of the bounding rectangles of sub-areas in real coordinate system are small than or equal to that of a pixel.

对于有等值线通过的子块，求出其包围盒的尺寸，如果小于等于一个像素，则把对应的像素设置为相应的颜色，否则，在母元中把子块继续4等分，直到实际坐标系中子块的包围盒尺寸小于一个像素为止。
