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:

1. Blue (= 0) -> Red (= 255), this is the default value
2. Green (= 0) -> Magenta (= 255)
3. White (= 0) -> Red (= 255)
4. Grey (< 128) / Red (> 128)
5. Blue -> Green -> Red (~ rainbow)

Warning

If there's an outlier in the data the color may seem uniform because of this outlier!

Note

A boost rounding exception error will be thrown if used with a non dense point cloud
