ABSTRACT This paper summarizes our researches on two key techniques in curve and surface modeling-the geometric approximation techniques and the geometric interpolation techniques. The former includes three types of geometric approximation techniques: Hybrid polynomial approximation to rational curves and surfaces, offset curves and surfaces approximation, interval Bézier curves and surfaces approximation. The latter includes a series of algorithms for shape blending modeling: the MSI algorithm for shape blending between space polylines or trees, the MSI algorithm for shape blending between triangular meshes, and skeleton-based shape blending algorithms using triangular decomposition and star-shape decomposition.

So basically all the modeling followed this workflow, most of the detailing as you can see has been left to my imagination, and it has been a lot of fun! After modeling all the armor, I modeled in subdivision some folds too in the underbody, just in those areas where they were more visible like the middle of the arms and the back of the knees.

因此基本上所有的建模都遵循这个流程，大多数你可以看到的细节，都被保留在我的想象中，因此这会有很多乐趣，当建完所有的盔甲，我还在身体上做了一些细分建模，就是没有被盔甲覆盖的暴露部位，比如手臂的中间，和膝盖的背面。

Those four classification models work well in first class of Chinese Vegetaion Division. The KAPPA value of Holdridge Life Zone System,at high value of 0.57,would probably more effective than the others. But in specific area,like tibetan plateau,all of those models need to be refined or consider more elements and factors. This research also points out that the concept and technology of Digitall Earth would promote and push forward the climate-vegetation relationship research,especially in climate-vegetation factors,climatically parameters and modeling parameters,real time dynamic monitoring,effectively managing the magnitude data of climate-vegetation relationship information and supporting the mainframe of Functional Types Modeling Library.
