Loch - display divided in quarter
by Enrico Fratnik 14 Feb '22

14 Feb '22

Hi everyone, I report a problem with loch model visualization. On my i7 laptop with osx 12.2.1 (but it was happening also before) I don't understand why the model display is only on a quarter of the screen (see attached image). If I move the window on the external monitor, the display returns to full screen. If I do not have an external display attached I am not able to restore the screen and loch becomes unusable. Any suggestions? Thank you enrico portable display [image: Screenshot 2022-02-14 at 07.26.15.jpg] external display [image: Screenshot 2022-02-14 at 08.37.10.jpg] -- Enrico Fratnik e. enrico.fratnik(a)gmail.com PEC enrico(a)pec.fratnik.it skype: fratnike t. +39.335.6573879 Questo messaggio e riservato; Qualsiasi pubblicazione, utilizzo o diffusione, anche parziale di questo messaggio, deve essere preventivamente autorizzata.

The inset map gives an overview/location reference, much the same as the navigation panel in an atlas. The maps share a common layout block in a shared thconfig file.

Hi, I think the following should work: 1) use \loadpicture{\pathvar} in the shared thconfig file 2) define \pathvar macro in the 'code tex-map' section of the customised thconfig file: \def\pathvar{yourfile.pdf} Martin On Tue, Feb 8, 2022 at 11:03 AM Nigel Cooke <nigel.cooke(a)bigpond.com> wrote: > > Good evening all, > > > > I am trying to pass a variable to the \loadpicture function in a tex-map code block.

Tex-map code for passing variables
by Nigel Cooke 08 Feb '22

08 Feb '22

Good evening all, I am trying to pass a variable to the \loadpicture function in a tex-map code block. As part of a \def\maplayout{ } block, I am using this line of code : \legendbox{100}{-3}{NE}{\loadpicture{output/ShadesOfDeath_HallOfTheMountainKingLocation-p.pdf}} to place a picture in the map header. This works fine but I need to pass in the file path as a variable. To put it in context, I have a suite of maps, each of which has a small inset map as part of the header. The inset map gives an overview/location reference, much the same as the navigation panel in an atlas. The maps share a common layout block in a shared thconfig file. Parameters in the shared layout are populated with map specific information via Therion data and some variables (eg \cavename) that I set in a thconfig file customised for the specific map. I want to keep the common layout generic in case I need to change it in the future and to avoid having to update it in numerous files. What I'm trying to do with \loadpicture is select the picture that is the location overview for the specific map. I can do it using a hardcoded file path but I need it to work with a variable that contains the file path. I would then set the variable in the thconfig for a specific map. The layout command ‘map-image’ doesn't work because I have redefined the \maplayout macro in a tex-map code block. Is it possible to pass a file path in a variable to the \loadpicture function? If so, can anyone show me some code that would to do it? I’ve tried reusing an existing variable like \the\comment but that only produces a compile error. My Tex knowledge is limited so I am struggling with working out how to set this up.

Hi, macOS users, I just updated my homebrew formulae and installation instructions to build & install Therion using CMAKE - see https://github.com/ladislavb/homebrew-therion <https://github.com/ladislavb/homebrew-therion> Installation was successfully tested on Apple Silicon machine running macOS 12.1 Monterey. Hopefully it still work on older versions but I am not able to test it - feedback is welcome. \Ladislav

How to calculate the volume of a cave
by Bill Gee 31 Jan '22

31 Jan '22

Hello everyone - What tools can be used to calculate the volume of a cave based on center line and LRUD data? I found an email from Martin Sluka from about 4 years ago describing how to use Loch to export a .lox file in other formats, then run that file through CloudCompare or ParaView. The process looks very complex to me, and besides - Loch does not run on my computers, so there is no way for me to generate an export. As far as I can tell, Survex does not have a way to calculate volume. Could it be done with a KML file and Google Earth? -- Bill Gee

Calculation of cave volume
by Bill Gee 28 Jan '22

28 Jan '22

Hello everyone - Several years ago I made a map of a small cave. Among the data that was calculated was an estimation of the volume of the cave. I need to find that information again, but it has so far eluded me. I thought it was in therion.log along with other statistics like length and bounding box dimensions, but now I do not find it there. The estimation was based on solids calculated from centerline and LRUD data. I looked in thTMPDIR and found nothing useful. I also checked to see if it comes from Aven or Loch. Nothing there. I looked through a KML file and found nothing. Can any of you point me in the right direction? Believe it or not, I need to testify in court early next week about this. It's a long story ... Thanks! ======== Bill Gee

Hide symbols within certain maps/subsurveys
by Tarquin Wilton-Jones 20 Jan '22

20 Jan '22

Hi folks, I have a survey of a cave and its surrounding surface area, including all the little caves in the area. So you can basically get an overview of the area, see the surface streams and sinks. Normally, I want the cave survey to be on its own, showing the cave's features, passage names, fill areas, boulders, water flow, etc.. But when I show the area overview, all those features become unimportant, and most labels should be hidden (only the cave names are important). When showing an overview though, I still want to show the surface labels, slopes, cliffs, water flow, arrows, borders, etc. Does anyone have a nice way to hide almost all symbols within one map/subsurvey (the cave), while showing them all within other maps (the surface)? Does Therion have a dedicated way to do this that I missed? Cheers, Tarquin

My take on a new Therion map editor
by Csongor Zih 16 Jan '22

16 Jan '22

Hi everyone! I'm a university student and I decided to try and make an XTherion replacement as a short term project. I have seen the activity here around making a new version of XTherion that would overhaul the current workflow of Therion projects. These proposals look exciting and great, but what I focused on was just creating an editor for TH2 files, that only replaces the map editor part of XTherion, and otherwise affects nothing about how you use Therion. It is most similar to the TH2 importer and exporter for Inkscape. Demo video: https://www.youtube.com/watch?v=kpogxtt_4TI This is only a feature showcase, the app is not ready to use yet, but you can try it out. The editor was built from the base of a regular vector graphics editing app, similarly to the Inkscape plugin. The whole app runs in a web browser, it's written in JavaScript and TypeScript, and it should run on all modern browsers. I have tried to set a very small scope for this project, this is why I didn't try to create a complete vector graphics editor and used an existing one. There is also no WYSIWYG editing, which would be hard to achieve without reimplementing the whole of Therion (obviously outside the plans for this project). The scope and functionality is significantly smaller than the *QTherion *or *Mapiah *projects, and I would expect that this editor would not be useful once these projects are in a usable state. The editor also has less functionality than XTherion itself, which I see as a trade-off between speed/friendliness and having complete control. One of these is that in this editor all area objects are tied one-to-one with line objects. This may not be how all people use areas, but it is easier to understand and to show on screen, and it's how *TopoDroid *handles it. I think while this app is not everything you might want from an editor, it has clear advantages over XTherion and is more streamlined than the Inkscape plugins, and a lot closer to being complete than the Qt projects currently in development. The project's name is currently wtherion (because it's web-based and because of the other project names), but this may change. It's on GitHub here: https://github.com/daem-on/wtherion Hope that this will be useful in the future and I look forward to your feedback, Csongor

Scallop symbol: elonged option?
by Benedikt Hallinger 05 Jan '22

05 Jan '22

Hi there, is there a way in which I can stretch the scallop symbol? I have some need for a streched version, but ideally this should probably be an option to the already existing symbol, shouldn't it?
