How to hide points with a given classification?

[mapdeep]

I saw the post here: http://www.danielgm.net/cc/forum/viewto ... ?f=9&t=190 , which clarifies how to visualize a point cloud using classification.
I am further wondering how I can do this, and then hide points with a given classification?

I tried to give transparent colors to the classes I wanted to hide (somewhat of a hack), but it seems that transparencies are not supported in this way.

thanks

If it's the very first or very last class (numerically speaking), you can simply use the 'min' and 'max' displayed value of the scalar field (with the 'show NaN/out of range values in grey' option disabled).

Otherwise, your only option is to 'segment out' the other classes (i.e. below and above the class you want to hide) so as to create two sub-clouds that you will display instead of the original cloud... Or at least create one sub-cloud wit the classes below for instance, and use the 'min displayed' parameter of the scalar field to only show the classes above.
