The VPB terrain system is mainly for non-dynamic terrain. Can you rely on shader support in your app? Some dynamic alteration would be possible by shaders. Also, you should not use just one gigantic heightfield entity of constant resolution. This is slow and inefficient. VPB/osgDEM splits your terrain into a quadtree of LODs, ensuring better clipping and decimation of detail. -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ "There is no Truth.
