目前,被誉为大自然的几何学的分形理论,已成为现代数学的一个新分支,但其本质却是一种新的世界观和方法论。它与动力系统的混沌理论交叉结合,相辅相成。它承认空间维数的变化既可以是离散的也可以是连续的,因而拓展了视野。分形技术提出后,在世界上引起了广泛重视,在数学、物理、化学、生物、经济学及计算机科学领域展开了分形理论、技术和应用的研究,逐渐发展并完善了分形理论体系。

我们将深入学习DirectX以及构成这项先进技术的所有基础组件。此外,我们还将详细讨论一下组件对象模型(COM),所有的DirectX组件都是由COM构成的。如果你只是一个C程序员的话,那你应当十分关注这部分内容。不要担心,我们将详细地讨论该内容。对于该部分内容,提出一点警告:在确定你不想掌握这部分内容之前,请阅读本章全部内容。DirectX和COM是相互关联的,没有另外一个很难解释其中任意一部分内容。

Visualisation, as the name might suggest, tends to concentrate on our visual system. Typically datasets are turned into 3D geometric entites, rendered to form 2D projections, and then presented to our eyes using digital monitors or projectors. The goal of the exercise is to improve or speed up our understanding of the underlying processes being studied. We do however have other senses that may be able to be exploited in the visualisation process, in particular, our sense of touch is regularly used to explore our physical world. This presentation will discuss the automatic creation real solid models from data which can then be explored simultaneously with our sense of vision and touch. Practical examples and applications will be demonstrated based upon the model creation hardware available at UWA.

Peter Doyle discovered the fact that a set of 6 circles arranged around a central circle ( a
‘flower’) may be extended to an infinite
hexagonal circle packing of the plane. ( which is possibly overlapping ,i.e. not coherent).
