Dear all, For a quite large project, I am using a relatively high-resolution DEM (i.e. 1 px = 1 m), and I am trying to use it within Therion to produce a .lox-3D file. I am however facing some problems: If I export the full resolution DEM to a .th file (6540*4307 cells) with the line "grid 325816.2990788577 5106250.599820679 1 1 6540 4307 ». I have the error « therion: error -- dem.th [14] -- line too long ». This line 14 correspond to the first row of the DEM. ASC parameters are « #NCOLS = 6540, NROWS = 4307, XLLCORNER = 325816.2990788577, YLLCORNER =5106250.599820679, CELLSIZE = 1.0 » If I export the DEM with a 5 m pixel resolution (1308*861 cells) (with the line "grid 325816.299079 5106250.59982 5.001161440185831 5.001161440185831 1308 861 », I get the same error, If I export the DEM with a 10 m pixel resolution (654 * 431 cells) (with the line « grid 325816.299079 5106250.59982 9.996519721577727 9.996519721577727 654 431 »), everything compiles OK and the result is quite OK (https://www.groupe-speleo-vulcain.com/wp-content/themes/custom_theme/3d/JB.h... ; be patient, it takes time to load), but not with the full resolution. The process to build each .th DEM is exactly the same, I do not touch any end of line. I edit the .asc DEM with vi to translate it into a .th file. I thus suspect that there is a size limitation for the DEM in Therion, I imagine a limitation in the number of row/columns of the DEM. Is that true ? If yes, what is this size limit for DEMs ? As anyone an idea how to overtake that and use the full resolution DEM ? Cheers, Xavier

Hi, I do strugle with the same problem, if I understand well; partly there is solution tu cut all grid values after f.e. second number behind point (if you have values like I do - 1205.648971354 and so), you fit almost twice of values into the line. I did not experiece any troubles with number of columns, so I suppose real solution would be to extend line in Therion, but I don´t know, if it´s possible.

Hi,I also tried to lower the DEM accuracy by cutting digits after the point but I got same error: line too long. In my case I have only 3 digits. I would know if it is a Therion limit and if it is somewhat possible to overcome it by, for example, recompiling Therion.

It looks like this line length limit is specified in thinput.cxx: const long thinput::max_line_size = 8128; So changing that and recompiling should help. Cheers, Olly
Hello, I recompiled Therion with a new limit and I generated the .lox model. No "line too long" error anymore. Unfortunately, I wasn't able to overlay a .jpg image. Therion overlayed only part of it over the whole DEM. Sligthly changing calibration data produce even weird result .. I'm starting tho think that there are some other constants to tweak somewhere else. I cannot attach the model because it is very large (about 200M).
