seafire6 0 Posted January 20, 2009 What is the best 3d terrain generator to use to create new islands/terrain for Arma? L3dt seems to have some promise but I'm sure there are probably others to consider. Any thoughts are appreciatted. Share this post Link to post Share on other sites
Nicholas Bell 0 Posted January 20, 2009 Wilbur is free and quite powerful. Â UI not real friendly, though. http://www.ridgenet.net/~jslayton/software.html I also use (and really like) Leveller, but it costs $150 US: http://www.daylongraphics.com/products/leveller/ Share this post Link to post Share on other sites
mikebart 1 Posted January 20, 2009 there's also a plugin for google earth that captures DEM data, and saves it out as a heightmap, im not too sure at what resolution though, but it could be possible to finish it off in photoshop or use it as a base in a terrain editing program.

seafire6 0 Posted January 21, 2009 Leveller looks good. It appears user friendly and conducive to large terrains. When you are finished in leveller how do you then get it into Visitor ? Share this post Link to post Share on other sites

The download sites for the STRM DEM data tied to that plug-in no longer work (at least last time I checked). Â Better to go to: http://seamless.usgs.gov/ The DEM data has to be scaled to whatever grid you are using to create your island/map - usually 10 or 20 meters. Â This scaling process is most easily done using MicroDEM, available free here: http://www.usna.edu/Users/oceano/pguth/website/microdem.htm A deep search in this forum using MicroDEM, DEM, Wilbur, etc will provide a lot of information on how to get from raw DEM to a Visitor usable heightmap. Of course raw DEM isn't exactly what you want to use in making a map because in most cases it is "smooth" - Â it is based on a 90 meter elevation grid. Â The points between are interpolated. Â To create realistic terrain one needs to use erosion routines to naturally sculpt the terrain. Â Most heightmap generators have some form of erosion routines. Â I've found that Wilbur's and Leveller's are the best at producing realistic results. Note that the US DEM is based on either at 30 meter - or in a few areas, a 10 meter grid, which provides a much more realistic heightmap to start. Share this post Link to post Share on other sites
mikebart 1 Posted January 21, 2009 Thanks for the info Nicholas, I havent really had any personal experience with height mapped terrains but for a flight combat game I recently worked on the terrain guys used Google earth DEM data and finished it off in Zbrush, then rendered another higher resolution heightmap from the mesh to be used in the game engine, but I guess those terrains didnt really require quite as much detail as an Arma terrain, so not too sure if thats any help.

seafire6 0 Posted January 22, 2009 Thanks for the replies. Does anyone have experience with Grome software? It also looks good. Share this post Link to post Share on other sites
.kju 3243 Posted January 22, 2009 GroIMP looks interesting. One had to check the data structure it imports/exports. Maybe we would be able to write a converter to v3 formats, if the app is good. Share this post Link to post Share on other sites
seafire6 0 Posted January 27, 2009 Please correct me if I'm wrong. It seems the most important components to a 3d terrain generator for Arma is the abliity to export the heightfield map in .png format? As far as a sat image it seems that a textured map image would sufffice. Share this post Link to post Share on other sites
[aps]gnat 28 Posted January 28, 2009 XYZ exported files can also be used with Visitor to mimic your terrain. Share this post Link to post Share on other sites
