Apologies for cross posting, but I think this is of general interest to Therion users too. I had not heard of this route to view 3D cave models in a stereoscopic viewer before. If Loch could export models in a standard 3D model format including the landscape overlays it would open up 3D viewing options. E.g. A side-by-side image pair video signal can be viewed in full colour 3D on many 3D TV sets and projectors. Loch does not provide a side by side option currently. If it could export models to a format another viewer can show then it gives a quick route to display models in this sort of way.<div><br></div><div>Footleg<br><br><div class="gmail_quote"><div dir="ltr">---------- Forwarded message ---------<br>From: Jarvist Moore Frost <br>Date: Thu, 1 Feb 2018 00:07<br>Subject: Re: Aven in stereoscopic 3D<br>To: Pedro Silva Pinto <br>Cc: <a href="mailto:survex@survex.com">survex@survex.com</a> <<a href="mailto:survex@survex.com">survex@survex.com</a>><br></div><br><br><div class="gmail_forwarded">Perhaps easiest is to extract the data & use with a more mainstream viewer.<br>

I had a lot of luck with Pymol (designed for biological molecules /<br>
molecular dynamics), and Thomas Holder's python library for directly<br>
importing .3d data:<br>

<br>
Pymol is open source, but a lot of the web links direct you to the pay<br>
version.<br>
<br>
Pymol supports all kinds of weird and wonderful 3D outputs, including<br>
shutter glasses. Mainly I've just used the 'cross eyed' stereo and anaglyph<br>
(coloured 3D specs).<br>
<br>
Back in ~2011 I wrote a C program that linked to Survex and exported the<br>
.3d file to a '.CGO' set of graphics primitives. This was a bit more<br>
clunky, but also worked fine.<br>
