Hello friends,

I have exported nodal, element data in vtk file to visualize in paraview. I have 6656 elements and each element has some rgb data {{0,1,0},{0.6,0.9,1}…..}*255 to make it consistent with paraview. Now how can i map this color data exactly to each element in paraview?? Looking forward for your help

Here is samaple code snippet:

In the Properties panel, select “ElementColors” in the Coloring menu and then uncheck the property Map Scalars. This tells ParaView to use the RGB values you have provided in the “ElementColors” array.
