Can L3DT be used for this? I have a very small scale GeoTIFF heightmap that I would like to cut into pieces and then use L3DT to extrapolate/interpolate a higher resolution terrain from each piece. Essentially what I want to do is to break the heightmap into 64x64 pixel pieces (each represents an area roughly 100x100 miles) and then (through some L3DT magic) create a 1024x1024 heightmap, distribution map, lightmap, etc.
Is this do-able with L3DT? If so, how do I go about doing this? If L3DT won't do this, any recommendations on an application that will?
Thanks very much!
