hi to all, I’m trying to use height and texture map created from WM inside OSG http://www.openscenegraph.com/ . i explained in this post of OSG forum the problem : http://forum.openscenegraph.org/viewtopic.php?t=11549 . Anyone has ever tried to do this?
i don’t find yet a solution for OSG but i was able to view a terrain created with WorldMachine within libMini viewer http://libmini.googlecode.com/ : this is a lib with which you can visualize terrains maps (you have to build it with a compiler or you can use the QT win binaries). I followed this steps: export your height map terrain as terragen file (.ter) and your bitmap texture map as tiff 16 bit. Import them in VTbuilder (you can download it from VTP web pages : http://vterrain.org/ ) as elevation for height map and as images for your texture bitmap ( you will ask to choose geo projection: use the predefined, you will also asked to specify the size. leave origin to 0.0 0.0 and size the size of your bitmap for ex. 512 512) . after that choose to export as libminitileset for the height and bitmap tex. Now you can run in a console: ./viewer /you/path/to/tileset (this in linux).
I discovered that also Enviro - the other software of vterrain.org - you can import the same maps and save as .osg ( the native file for openSceneGraph) but i don’t know if it is possible to export a tileset in this way… Maybe you can export in VTBuilder as .tiff in a similar way as i did for libMini. the big problem was that those .tiff lack of cs georef , trying to add them with gdal utilities not help ( or at least i was not able…). so i have to try agin with VTBuilder… will see…
Thanks for attention.
I solved this. the most important thing is to export in a 8bit format the height texture and the imagery texture. then import them as separate level ( as elevation or imagery) in VTBuilder adjust origin, dimensions and/or geocoordinates then export them as png . At this point follow the usually procedure described in the osgdem page to create a .ive or an .osgb for a tileset. I will do a little tutorial as soon i will finish my personal web page.
It will be also interesting develop a plugin to export to .osg or .ive as for example Grome is capable to do.
