这是一本系统介绍Cinema 4D R17基本功能以及运用技巧的书。全书共27章，每章单独介绍一块内容，讲解过程细腻，实例丰富，读者可以轻松地掌握软件技术。 本次分享两块内容，一个是大部分三维软件支持的一种优秀的建模方式——NURBS，它能够很好地控制物体表面的曲线度，从而创建出更逼真、更生动的造型；另一个是可以自由组合出各种不同效果的“造型工具”，它的可操控性和灵活性是其他三维软件无法比拟的。

Learning Python 5th Edition （Python学习手册第五版）可复制粘贴，有目录
This fifth edition completed in 2013 is a revision of the prior, updated to cover both Python 3.3 and 2.7, the current latest releases in the 3.X and 2.X lines. It ncorporates all language changes introduced in each line since the prior edition was published, and has been polished throughout to update and sharpen its presentation. Specifically:
• Python 2.X coverage here has been updated to include features such as dictionary and set comprehensions that were formerly for 3.X only, but have been back-ported for use in 2.7.
• Python 3.X coverage has been augmented for new yield and raise syntax; the __pycache__ bytecode model; 3.3 namespace packages; PyDoc’s all-browser mode; Unicode literal and storage changes; and the new Windows launcher shipped with 3.3.
• Assorted new or expanded coverage for JSON, timeit, PyPy, os.popen, generators, recursion, weak references, __mro__, __iter__, super, __slots__, metaclasses, descriptors,random, Sphinx, and more has been added, along with a general increase in 2.X compatibility in both examples and narrative.
