Hi Uma, You might want to also look at VTK/ParaView which has some features but event then it is a non-trivial task.
A while ago I needed to calculate the frontal area and it turned out easier to just render it and pixel count. The issues were due to how select works. As the GPU is optimising the rendering, it is not drawing all the triangles, if you then select and calculate on that select you will not get the correct answer. You may be able to do a variation with slicing and pixel counting (in either VTK or OSG) - my random nodes/coda here: https://github.com/internetscooter/Vespa-Labs/tree/master/VespaCFD/CalculateFrontalArea Cheers, Paul ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=69451#69451 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
