关于Demonoid的介绍

Demonoid,是一个BitTorrent 网站，因为能够提供丰富优质的Torrents下载，受到很多人的青睐。
但为了减轻网站的承载负担，于是限制了注册，需要有人邀请，发送邀请码才能注册。
网站是由一个匿名的名南斯拉夫人于2003年4月21日建立的。
这个网站的注册会员（免费注册）需每周在网站上下3个以上的BT文件，或者得要定期下载一些旧的BT文件。（可想而知，BT一些旧美剧以及旧版兼容软件速度会不耐）。

我个人很喜欢 P2P 这个伟大的发明，它让我们有机会接触到更多优秀的信息和内容。但知识产权也是应该得到保护的。在“分享”已经成为主旋律的今天，我个人认为版权保护和分享 本身不应该是矛盾的对立双方，单纯的买卖关系已经不适应现在的分享方式。探寻新的分享方式，使分享方和版权所有者能达到双赢，才是 Torrent 组织和版权保护组织真正应该坐下来讨论的事情。

Demonoid.com以前每周五可以免费开放注册，但2007年3月3日网站宣告：以后每月开放注册一次。此外，想要注册的人只能通过现有注册人员发送的邀请码，在网站未开放免费注册的时间里注册。
实在需要邀请码的来这里看看http://blog.119797.com/article/demonoid-invitation-codes/

plugin | unroll srf or brep into ordered plan

 

This little code is just for unroll a bunch of surfaces. The parameter include ordering by "bounding box size" or by spatial location, with or without labels.

if no srf or brep is selected, will show: , if only one srf  is selected will show: , lol….

the core of the code is the “order by size” and the “smash” rhino command.

these are the samples:

                without label                                          with/without label                     

                   by spatial relation                                             by size

 

Click to download plugin: drag to your rhino and you are all set.

Run it by typing command "xUnroll" or go to the menu "xTools".
