<div dir="ltr">Hi Howard,<div>I think something is not quite right in Windows-land.</div><div><br></div><div>1) I was not able to compile in release mode in Win32, lots of errors that I did not chase down yet.</div><div>2) On my laptop, I get the memory fault with a single cache_block.</div>
<div>3) On the server, it works reasonably well, but still fairly slow (although faster than with 3 cache blocks). It is good enough for now.</div><div>4) I tried just exporting to the las file like you did on the server, and it is about the same speed as the pgpointcloud pipeline, about 5 minutes for the sample file on a pretty fast machine.</div>
<div>5) I never did try the branch you sent me, this is the main branch from last week that I'm testing.</div><div><br></div><div>So, I'm going to leave it the way it is for now while I do some other things, like export and visualization. I'll come back to the speed and compile issues later on.</div>
<div><br></div><div>Thanks for your help!</div><div>Roger</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Thu, Jul 18, 2013 at 10:27 PM, Howard Butler <span dir="ltr"><<a href="mailto:hobu.inc@gmail.com" target="_blank">hobu.inc@gmail.com</a>></span> wrote:<br>
