Hello,<br> I'm doing some experiments and changes to the VTK's CastRay function (file vtkVolumeRayCastCompositeFunction.cxx). In one of the experiments I would like to do, I need to get the actual direction of each voxel's gradient.<br> My question is, how can I convert(decode) the staticInfo->EncodedNormals to get the actual direction computed at vtkFiniteDifferenceGradientEstimator.cxx? (i.e. n[0], n[1], n[2])<br> <br> Thanks in advance.<br> --John<br><p>
