There's a patent on it, but there's also previous work: see DBD::Chart and DBIx::Chart (perl modules). The key is to both provide an API and a query language I believe. Just looking up geometric queries, it looks like you would need a GPU, perhaps several on your server to provide fast search.<div><br></div><div><br></div><div>You've probably seen this demo: <a href="http://www.youtube.com/watch?v=3bKphYfUk-M">http://www.youtube.com/watch?v=3bKphYfUk-M</a> wonder what the database behind this is.</div><meta charset="utf-8"><div>John<br><div><div>On Apr 30, 2010, at 5:34 PM, Dave A wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>I'm wondering if anyone is familiar with true 3D databases.
