Shawn, I tried it your way in ParaView 5.3.0, and it did not work correctly. Are you sure this is implemented in 5.3 and not a new feature in the upcoming 5.4?

I'll just add that if the data is floating point in the range [0, 1], you don't need to convert it to uint8 or multiply by 255. Just creating a floating point vector will give the same result. This is a more recent extension of the functionality: I know it works in 5.3 and master but I'm not sure how many versions back support it. A = inputs[0].CellData['A'] B = inputs[0].CellData['B'] C = inputs[0].CellData['C'] colors = numpy.empty((len(A),3), dtype='float') colors[:,0] = A colors[:,1] = B colors[:,2] = C output.CellData.append(colors, 'colors') HTH, Shawn On Mon, May 8, 2017 at 1:56 PM, Moreland, Kenneth <[email protected]<mailto:[email protected]>> wrote: ParaView does not directly support ternary color maps, but if you create a field of colors (represented by three unsigned chars), then you can render those colors directly by turning off the Map Scalars option. You can create these colors with a Programmable Filter with a script like the following: A = inputs[0].CellData['A'] B = inputs[0].CellData['B'] C = inputs[0].CellData['C'] colors = numpy.empty((len(A),3), dtype='uint8') colors[:,0] = A*255 colors[:,1] = B*255 colors[:,2] = C*255 output.CellData.append(colors, 'colors') Once you apply that script, color by the new “colors” array and uncheck the box marked “Map Scalars” (it is an advanced option in the properties panel). -Ken From: ParaView [mailto:[email protected]<mailto:[email protected]>] On Behalf Of Thomas Oliveira Sent: Saturday, May 6, 2017 7:24 AM To: ParaView <[email protected]<mailto:[email protected]>> Subject: [EXTERNAL] [Paraview] Visualization ternary saturation Dear all, Given three cell arrays (A,B,C) representation saturations (A+B+C = 1 for every cell) is it possible to generate a ternary saturation image like the one attached (obtained in http://www.esss.com.br/Kraken/wp-content/uploads/2014/07/Ternary-Saturation.png)? In the figure, A, B, C are saturations of water, oil and gas.
