I have been making enhancements to VPB and OSG to support this sort of deformation. While my work is not complete, doing a trivial flatten-within-rectangular-region would not be tough for you to implement. I have made changes to support VPB terrain elevation alteration during load/save operations (through a pseudoloader) or during the initial VPB build time (via a callback). If this would work for you, I can explain more. -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ "There is no Truth.
