Hi All,

I have been trying out the function wlop_simplify_and_regularize_point_set()
in CGAL v4.12 master build, trying to simplify and regularize my very dense
scanned point cloud in .las format, where it comes with RGBI property.
The result looks very good, however, I am facing two issues unsolved, and
would like to seek advise:

1. The output of wlop_simplify_and_regularize_point_set() is only a list of
points with only position information. From my understanding on how WLOP
works, my points are not just sampled, but some of them also re-positioned.
Thus, how am I suppose to map back my RGBI from my original point set to the
new WLOP processed point set? Or otherwise, the color info is lost.

2. Instead of color, I might later on want to input a point set with texture
coordinates. Similar with problem 1 above, how am I suppose to retain (or
remap) the texture coordinates to the new WLOP processed point set?

Thank you, and hope I could get some advise here.

William
