But this is exciting anyway. 2005-02-22T13:57:05Z 2005-02-22T13:57:05Z https://gamma.unpythonic.net/01109080625 <div style="float:right;clear:right"><!-- crane-out.png--><div class=albumouter style=width:704.0px id=><div class=albumimage style="width:405px;margin-left:149.5px;"><a href="https://media.unpythonic.net/emergent-files/01109080625/crane-out.png" class="thickbox" rel="album" title="crane-out"><img src="https://media.unpythonic.net/emergent-files/01109080625/crane-out-small.png" width=399 height=209></a><div ><div style="float: right" ><a href="https://media.unpythonic.net/emergent-files/01109080625/crane-out.png"><img class=zoom src="https://media.unpythonic.net/emergent-files/default/zoom.png"></a></div><a href="https://media.unpythonic.net/emergent-files/01109080625/crane-out.png">crane-out</a></div></div></div> </div> This image has 12k points. I don't think this many points are practical on the mill, but it looks pretty good onscreen. Screenshot from the stippler software, resized and cropped with gimp. 2005-02-21T17:13:30Z 2005-02-21T17:13:30Z https://gamma.unpythonic.net/01109006010 <div style="float:right;clear:right"><!-- marie-variable.png--><div class=albumouter style=width:678.0000000000001px id=><div class=albumimage style="width:379px;margin-left:149.50000000000006px;"><a href="https://media.unpythonic.net/emergent-files/01109006010/marie-variable.png" class="thickbox" rel="album" title="marie-variable"><img src="https://media.unpythonic.net/emergent-files/01109006010/marie-variable-small.png" width=373 height=300></a><div ><div style="float: right" ><a href="https://media.unpythonic.net/emergent-files/01109006010/marie-variable.png"><img class=zoom src="https://media.unpythonic.net/emergent-files/default/zoom.png"></a></div><a href="https://media.unpythonic.net/emergent-files/01109006010/marie-variable.png">marie-variable</a></div></div></div> </div> (3500 points) <p>This uses the formula <tt>1 + density * 4 / max_density</tt> which looked better than the &quot;correct&quot; version with sqrt. It remains to be seen how well this effect can be seen when hole-depth is varied. 2005-02-17T03:37:52Z 2005-02-17T03:37:52Z https://gamma.unpythonic.net/01108611472 A few weeks ago, I stumbled over a paper by <a href="http://www.cs.ubc.ca/~ajsecord">Adrian Secord</a> describing an algorithm to turn a greyscale image into stipples. Here are the results of my implementation of his algorithm. UPDATE: I added the original photo of Marie, as well as the version that was used as input by stippler.
