Hey. I'm trying to get the surface bitmap working on 3d model in loch. What file format should the bitmap be in? jpg format compiles but nothing shows up in the model. An example would be really helpful. Philip Schuchardt

Hi, some test data is here: http://perswww.kuleuven.be/~u0049353/therion/test.zip When I remember right you have to specify at the elevation model the coordinates of the cell center. Some comments are in the files. And you are right you need jpg format. If you have questions feel free to ask. Wolfgang

perhaps one more comment on the elevation matrix: - you need to specify the upper/left entry of the matrix M[0,0], in my example the rows are ordered from south to north and the columns east west. That is why Y-step is positive. You can also start with your north-western corner and set Y-step negative... Regards Wolfgang It would be too nice if therion could read directly georeferenced files (for elevation field ie. [1] and images (jpg with world file .wld or .jgw [2])).
