		<description><![CDATA[There has been a bit of head scratching as other distractions apparently clouded an obvious scale issue.  The first terrain megaprim sculptie project done last month, had available imagery at 30cm.  For that, it only made sense to oversample to 25cm to make 512&#215;512 textures.  That decision led to my adding a collar around [...]]]></description>

Berkeley has [...]]]></description>

		<description><![CDATA[The past four days have been a tremendous blur of internalizing NURBS into my mind, at least the SL sculptie variant of them.  Now I&#8217;ve been aware for several months of how NASA used sculpted prims to represent detailed Mars craters (as published by Ireton), and I&#8217;ve certainly followed the beautiful work for David [...]]]></description>

Over the past four weeks I&#8217;ve participated in a burst of effort that has involved multiple resolutions of GIS data to describe a campus terrain in an eastern US state.  It&#8217;s been over twelve years since I&#8217;d worked with a 3D CAD design for a slope design, and this one brought back memories and [...]]]></description>

My humble trash-to-testing server, 1 GHz Celeron, 1.5 GB memory, Ubuntu Gutsy Gibbon, is now running at capacity: 49 standalone OpenSim regions, seamlessly covered in 1:4.57-scale real-life terrain, a single user and just the first couple of prims.
