Hi, In order to accelerate the learning curve of Therion, and convince more other club members (not English speaking), and I have updated the Therion and Xtherion Spanish translation, fillingthe empty "es" in the files texts.txt and xtexts.txt. I need someone to incorporatethis files to the program, and make a new Windows compilation to have a new windows binary with the new spanish translation to distribute to the spanish community. Thanks, Evaristo Quiroga

Overlaying xvi file and map background as the same scale
by Martin KERN 06 Feb '18

06 Feb '18

Hi, I want “Therionise” a cave map wich is alredy drawn. I have the data survey but not the vector data. - I created a centerline - I digitalized the map. - I import it and the xvi file in my .th2 as backgrounds. The problem is that scale of xvi file and map image are not the same. How can I overlay them at the same scale? Thank’s and sorry for my bad English, Martin

Hi Martin, Thanks for your answer. I want overlay .xvi file and image file for two reasons. 1) I can see if the old survey what I have is correctly drawn, so if stations of .xvi and image are on the same position. 2) This cave is still in exploration. When I will add new stations, how I’ll draw them if the xvi and the first part of the cave are not on the same scale ?

Rope and anchors symbols
by Evaristo Quiroga 03 Feb '18

Hi, I greatly appreciate the improvement made by Vladimir at the rope line symbol. https://www.mail-archive.com/therion@speleo.sk/msg05992.html With this symbol you can control if the rope section has anchors and rebelays, as line options. This options are global to the line: have or not rebelays or anchors. Now a I need to go more ahead, I want control the anchor type (natural: tree, block, etc or artificial: spit, multimonti, parabolt, etc) in every point and the rebelay in previous section. I want a round point for artificial anchor (like the Vladimir symbol) and a triangle point for natural anchor. When we rig with Y knots and deviators you need to control the line section without rebelays and anchors, so that the rope is straight and the knots do not appear as anchors. (see attached figure). Now I have to way to implement this in Therion: the easy and the elegant. Easy. Create two new point symbols for natural and artificial anchors. And use the rope line symbol with rebelay and anchor OFF in the rope section with Y and deviators, and ON in the other sections. Elegant. Create a new rope line symbol, where I can control in every point the anchor type (Natural, Artificial or None, for knot) and the rebelay rope effect in the previous rope section. I think we can do this by defining options to the line point. I know other have implemented similar option, like "adjust horizontal". To do this a need code examples with similar option implementation to inspire me. Thanks, Evaristo.

Fwd: Aven in stereoscopic 3D

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.

I had a lot of luck with Pymol (designed for biological molecules / molecular dynamics), and Thomas Holder's python library for directly importing .3d data: https://github.com/jarvist/migovecsurveydata/tree/master/scripts/pymol Example video: https://www.youtube.com/watch?v=s68V9EsRvmE Pymol is open source, but a lot of the web links direct you to the pay version. Pymol supports all kinds of weird and wonderful 3D outputs, including shutter glasses. Mainly I've just used the 'cross eyed' stereo and anaglyph (coloured 3D specs). Back in ~2011 I wrote a C program that linked to Survex and exported the .3d file to a '.CGO' set of graphics primitives. This was a bit more clunky, but also worked fine.

3D output file for printing
by franck TUOT 01 Feb '18

01 Feb '18

Hello, I was wondering if someone already tried to print some caves in 3D, using a 3D printer. Any input about how to get a .STL .OBJ .AMF or .3MF (which I know are 3D format for printer). If someone did a printing, any issue / success to share ? Like I guess any small narrow passage will be hard to print if the final print put some kind of pressure on it. Everything will depend of the scale obviously. Anyway, maybe it’s just a dream but I thought it’ll be possible to do such a thing those days : ) Have a good evening everybody, Franck Tuot
