I want to select vertex by color. At the moment I want to select the cells with (R,G,B)=(0,0,0). What function should I write?

r=0 and g=0 and b=0 doens't work.

And if I want to pick (R,G,B)=(255,255,255)? Or any other combination?

This question might be strange but I guess these colors don't vary between 0 and 255. They seem to vary between 0 and 1 instead.

Regards

Maria

You need to use r == 0 instead of r = 0 for "equals". This has been fixed in the 2016.12 documentation I believe, but is incorrect in older versions. MeshLab uses the muparser library for its filter functions; you can view all the built-in functions and operators here.

Also, MeshLab does use color values in the range 0-255.
