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.

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. Pavel

Hello, I'm facing same problem.
Any hint/answer? Thanks, Marco

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 [1] [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
