Ken, This was implemented some time ago. In 5.3.0, I could do the following: * Add Sphere Source * Add Programmable Filter with the Script set to A = inputs[0].PointData['Normals'][:,0] B = inputs[0].PointData['Normals'][:,1] C = inputs[0].PointData['Normals'][:,2] colors = numpy.empty((len(A),3), dtype='float') colors[:,0] = A colors[:,1] = B colors[:,2] = C output.PointData.append(colors, 'colors') * Turn off Map Scalars You could also skip this silly use of the Programmable Filter altogether and color the Sphere source by 'Normals', then turn Map Scalars off. I believe the capability to treat floating-point arrays of 3-tuples was added to VTK in commit commit 00de9a942ff74e797fbe4cd8c67307c8065cdade Author: Dan Lipsa <[email protected]> Date: Thu Nov 20 13:35:35 2014 -0500 Add VTK_COLOR_MODE_DIRECT_SCALARS.
