In viewing of accelerating animation rendering technique, this paper includes three parts of the author's work. First, the paper summaries an accelerating rendering method using frame-to-frame coherence. The paper also introduces an accelerating algorithm of span scanline tracing animation rendering as one implementation of the method.

The basic light setup consists of a main spot light (better if it's not much coloured) and a back omni light. Place a few omni lights for the glowing parts here and there. I didn't involve any global illumination, just a plain scanline render because another pass of ambient occlusion will be involved later.

基本的灯光设置包括一个主聚光灯（如果它不包含那么丰富的色彩，那就更好）和一盏背光灯，对于有光晕的地方放置一些omni，我没有加入全局照明，只是一个简单的扫描线渲染，因为另外的ambient occlusion渲染层会在晚些时候被包括进来。

The lecture includes practical demos in Adobe Photoshop? and 3d Studio Max?, using the Scanline, Brazil and Mental Ray renderers.

包括在Adobe Photoshop 3D Max中的实际演示，利用扫描线，巴西渲染和Mental Ray 渲染器。

Based on the feature of line scanning ,the change of slope of the scanning line is used as the compression rule on the spatial point cloud data.

The innovations of this paper as follows:(1)The topological relation model between complex spatial objects is brought forward, which represented by some composite basic 9I matrix and results in general signification.(2)Time and space integrated topological model is suggested to reason about spatio-temporal change types;(3)Sweep-line algorithm is improved, and a new little circles of polyline nodes overlapped with region method is proposed. As result, it's efficient to calculate line-line, line-region and region-region topological relations.

本文的创新之处在于提出了一种能够描述复杂对象的数学表达模型，将复杂对象间的复合拓扑关系表示成基本拓扑关系的组合，具有一定的普适意义；研究了时空拓扑关系的内涵和表达方法，说明利用时空拓扑关系可隐性地实现时空变化语义的查询；对平面扫描线法进行了改进，提出了一种新的节点微小圆求交的算法，可有效地解决线面、线线、面面拓扑关系的计算问题。

Theoretically, the width of the scanning line is equal to the width of melting zone and a mathematic model is set up.

扫描线宽理论上应等于熔融区的宽度，并在此基础上建立了一个数学模型。

The firstalgorithm ensures the disparity smoothness in horizontal direction by adaptivesegmentation on scan lines, and smoothes the disparity map in vertical direction by using astrategy of hypothesizing depth from neighboring segments.

第一个算法，通过扫描线自适应分割保证了段内视差的平滑性，通过段内视差拟和以及假设验证法保证视差在垂直方向的平滑性。

The mathematical model by which the forming time can be precisely calculated is ratiocinated. This model shows that in SLS the scanning "delay" phenomenon can make the actual forming time greatly exceed the theoretical time, and the total number, total length of the scanning lines and the scanning speed have different effects on the scanning "delay".

本文推导出了SLS成型时间精确计算的数学模型，该模型显示在SLS加工中的扫描&延时&现象会造成实际成型时间远远大于理论时间，并且扫描线条数、扫描线总长和扫描速度对扫描&延时&有不同程度的影响。
