I really think your best bet is to expand the input data to a rectangular input, use OSG's PagedLOD and tag your no-data vertices somehow. Then you can have a vertex shader and a fragment shader that can discard polygons that touch no-data, as well as allowing some sort of runtime-override of the vertex attributes to feed modified height values to the vertex shader. I'd be happy to consult on a project like this if you think it's beyond you. -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ "There is no Truth.
