Color point cloud on X,Y or Z axis using a Look-Up Table (LUT) Computes a LUT and color the cloud accordingly, available color palettes are :

Values are on a scale from 0 to 255: 0. Blue (= 0) -> Red (= 255), this is the default value

  1. Green (= 0) -> Magenta (= 255)
  2. White (= 0) -> Red (= 255)
  3. Grey (< 128) / Red (> 128)
  4. Blue -> Green -> Red (~ rainbow)
Warning
If there's an outlier in the data the color may seem uniform because of this outlier!
Note
