[原创]十三阶魔方及其结构

纸做的魔方

纸做的魔方

<p>&nbsp;每一个层面都是这样的凹凸槽，相互卡住，最中心一块由轴连住</p><p> </p><p>可以看到，每一个角块都有三个与之相邻的块卡住，即使转到外面，也有两个卡住它，使之不会掉出&nbsp;</p> <br/>

<p>不错，但是旋转的时候不光是角块，角块旁边的几个棱块甚至面块掉下来了怎么办？</p><p>我想它的结构问题没有你描述的那么简单吧。</p>

<p>从理论上说是可行的，常规的设计角块是由三个方向固定的，楼主所说的阶角块与棱块是由两个方向固定应该也是可以的。</p><p>老外有相似的这种魔方设计，但老外所设计的角块还是由三个方向固定的，应该可推广成楼主的那种</p><p>见：<a href="http://twistypuzzles.com/forum/viewtopic.php?t=6187&amp;highlight=pyraminx">http://twistypuzzles.com/forum/viewtopic.php?t=6187&amp;highlight=pyraminx</a></p><p>Sorry folks with dial-up this may be slow. <br/><br/>Anyways, lets start at the beginning. This idea came to me after seeing this video: <br/><br/><a class="postlink" href="http://tinyurl.com/y4jrev" target="_blank">http://tinyurl.com/y4jrev</a>
                <br/><br/>It was pointed out in this thread: <br/><br/><a class="postlink" href="http://twistypuzzles.com/forum/viewtopic.php?t=5653" target="_blank">http://twistypuzzles.com/forum/viewtopic.php?t=5653</a>
                <br/><br/>In that thread you can also see the beginnings of this idea here: <br/><br/><img title="Image" alt="Image" src="http://www.wwwmwww.com/Puzzle/hollow555.png" border="0"/>
                <br/><br/>The idea is further discussed here: <br/><br/><a class="postlink" href="http://twistypuzzles.com/forum/viewtopic.php?t=5719" target="_blank">http://twistypuzzles.com/forum/viewtopic.php?t=5719</a>
                <br/><br/>and here: <br/><br/><a class="postlink" href="http://twistypuzzles.com/forum/viewtopic.php?t=1359&amp;start=50" target="_blank">http://twistypuzzles.com/forum/viewtopic.php?t=1359&amp;start=50</a>
                <br/><br/>And I can already see some of you saying "That's a 5x5x5, why is this thread titled a new 3x3x3?" Give me a minute and I'll explain... <br/><br/>Lets build the 5x5x5 first. Its built from 6 different pieces and for each I have an animation and a picture I want to post. I'll put each in its own post below. <br/><br/>Carl</p>

Lets start with the corners: <br/><br/><img title="Image" alt="Image" src="http://www.wwwmwww.com/Puzzle/Corner.gif" border="0"/>
        <br/><br/>You need 8 of these: <br/><br/><img title="Image" alt="Image" src="http://www.wwwmwww.com/Puzzle/Corner.png" border="0"/>

Next come the edge pieces: <br/><br/><img title="Image" alt="Image" src="http://www.wwwmwww.com/Puzzle/Edge1.gif" border="0"/>
        <br/><br/>You need 24 of these: <br/><br/><img title="Image" alt="Image" src="http://www.wwwmwww.com/Puzzle/Edge1.png" border="0"/>

The other edge piece: <br/><br/><img title="Image" alt="Image" src="http://www.wwwmwww.com/Puzzle/Edge2.gif" border="0"/>
        <br/><br/>You need 12 of these: <br/><br/><img title="Image" alt="Image" src="http://www.wwwmwww.com/Puzzle/Edge2.png" border="0"/>
