I have three column vectors xp, yp, zp, where each column set of these vectors form the coordinate for a point in 3d space. I used plot3 function to plot the scattered points. however, the result showed that my points has a pattern as shown in the attached figure. I am seeking for a method to let the scattered points have colour rather than one colour plot. it is not possible to look after each point and colour it according to its z-value, even with for loop, because I have large number of points

scatter3(x, y, z, pointsize, color)
The color can be the z if appropriate.
If each of the "sheets should be a different color then that could be more difficult. Perhaps using a k nearest neighbor search and some kind of region growing?
Perhaps knnsearch of random point, fit a plane, find all points within a distance of that plane, consider them to be part of the same plane, associate a label, remove those from the active set, repeat with remaining points?
