Well, OSG can probably handle the fast part, but the graphing part will leave you kind of on your own. Depending on how much data rate you're jamming into the graph, it might be easier to use something like GNUplot: http://www.gnuplot.info/ It has all your graphing capabilities. I am unsure of the performance of it. If need be, you might have to try coupling the GNUplot graphing front end with an OSG graphics backend to actually put the graphs onscreen rapidly (especially in 3D). -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ "There is no Truth.
