Thanks for the input. I'm somewhat familiar with VTP but not with libmini. I'll poke around to get more info...

There was some work to create a FadeLOD years ago: http://archive.netbsd.se/?ml=openscenegraph-users&a=2005-02&t=1628815 But I'm not sure where it stands. I couldn't find FadeLOD last time I looked. If you want geomorphing, you should consider using a library like libmini or VTP (which can use libmini and supplies other nice frills too). http://vterrain.org -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ "There is no Truth.
