Thanks a lot, first, to Martin (Sluka), Stacho, and Erica for their kindness, for taking me in charge in Praha and Hriby, and for everything they have arranged for this nice session. We were able to have quite an efficient session, and plenty of interesting duscussion on therion present and future, on caving in general, on caves in the check ans slovak republics, in france or elsewhere, on environment, on cave management, on Prague history, on Europe, ....etc. yesterday before leaving, I promissed to make a short report from my notes, so there it is, presented as a list of topics/questions, and when possible a sketch of answers... - Therion not running properly on my W2000 Pro laptop (message "cannot read file data.log"...). => this was in fact a conflict with another installation of latex on the machine, that had set a bunch of latex variables. solution: unset all latex variables before running therion. May be this could be done in the therion script... => should go to the FAQ - Extended elevation not working properly on the Pinée example. => Stacho suggested that this was a problem with the order of the station points in the map file. Indeed this order is significant. But it is not the only problem: Back home I have set the correct order, and the result is still not correct. Stacho, I will send you the files when I have a moment (too bad I had not them on my machine in Hriby); And I will try other (smaller) examples... - A lot of problems with the definition of OUTLINES in the Pinée plan maps. I understand better the outline notion now, and I will spend some time correcting the Pinée exemple. I will definitely try to write some tutorial-like section about this topic. - Split Line bug: when you split an existing line in the map editor, save the file and reload it, one half of the line disappears... => Stacho will have a look... - Cross sections. various discusions, several questions: arrows (or marks) are not displayed by default; have to use e.g. "-direction begin" cross-section lines and scraps must be refered by a common id (or "name"). This will be useful to set references when the section scrap is far from the position of its reference line on the map. The labels naming the sections would be left to be user-defined (but maybe with a specific type, so that one can "hide" them together with the section lines/scraps). - Possibility of translating a part of a map (a scrap?) for avoiding overlapping drawings in some cases. This I originaly asked for extended elevation, where it is most useful, but the mechanism would be the same for other sorts of projections. One difficulty is that one would want to specify where to draw connection lines between the two parts. This is NOT a map object, but rather something similar to "joins". - Transparency for overlapping passages. This is currently handled using transparency and opacity at the PDF level. If one would want to draw the lower level wall using interupted lines (as in the UIS standard), it would have to be computed directly in therion, that would be too much work. => Abandonned. - Tricks and Tips: How do you know which side of a line is the interior (e.g. for a pit...)? Stacho showed me that on the first point of the line there is a small (red ?) arrow, that I would not have seen without my glasses (;-). This is a new feature, not in the Book; very useful. - Production of plans at very large scale (e.g. for inclusion in a topographic map). We need: (1) filling of the passage with colors, (2) specify a large scale bar and (3) a large north direction arrow. => (1) and (2) are feasible, e.g.: symbol-hide group all color map-fg [100 0 0] scale-bar 100 m Having several colors on the same plan (different for galeries and sumps, e.g.) does not seem possible. Having a bigger North arrow (for geo-referencing of the resulting map) should be done in Latex... - Printing of grids on the plan: currently not available. - New symbols: Ropes (for elevations) Meander in ceiling, in floor - Drawing of centerlines, even when you don't have the corresponding scrap. I would find it very useful for a quick evening printing when you do not have enough time for more. Martin Sluka disagrees, because he always draws on scale in the cave (different habits...); but still you have to scan the scraps and edit the map... Long discussions on 3D modelling that I will not try to summary (:-( Cheers, and thanks again, Eric.
