[Paraview] RGB color coding

[David E DeMarle]

I'ld use the python programmable filter.
In the filter:
copy the input across
make a new three component wide unsigned char array and give it a name
iterate over all the points (or cells)
   get the vector for the point (or cell)
   scale and bias each component down to 0..255 and store in the new array
add the new array to the output point (or cell) array container


see: http://www.paraview.org/Wiki/Python_Programmable_Filter
for starter examples
