			<content:encoded><![CDATA[<p>We?ve been keeping it under our hats for a while now but the code is nearing completion so it?s time to reveal one of the latest major features we?ve been adding to PatchBox: 3D Scanning.</p>
<p><a href="http://www.bigfug.com/wp-content/uploads/2009/09/20090906233010Snap00.png"><img style="border-bottom: 0px; border-left: 0px; display: inline; border-top: 0px; border-right: 0px" title="2009-09-06 23-30-10 - Snap00" src="http://www.bigfug.com/wp-content/uploads/2009/09/20090906233010Snap00_thumb.png" border="0" alt="2009-09-06 23-30-10 - Snap00" width="644" height="443" /></a></p>
<p>The image above was created using one projector and one camera resulting in a 300,000 point cloud.? We haven?t smoothed this geometry yet, which is why it?s all bumpy ? it?s the raw feed from the system.? The large holes were in shadow, or were non-reflective such as the monitor screen.? The small holes (such as those on the keyboard) are caused by scanning errors larger than 1cm.</p>
<p>As well as taking stylised self portraits (!), we?ll be using this technology to perform dynamic projective geometry and a myriad of other real-time visual tricks that we?ve been planning for years.</p>
<p>The 3D scanning and associated camera/projector calibration systems are also extremely useful for correctly projecting on curved and other non-planar screens.</p>
