Points visible only from certain angles
« on: August 31, 2023, 10:03:58 AM »
Hi!
im trying to filter out low quality points from my dense cloud using the filter på confidence option.
when i filter out my points i select them with the selection tool and delete them.
the problem is when i zoom or change the viewing angle new points apear!
it makes it impossible to know if al the bad points are deleted.
am i doing something wrong?

in the pictures below the red box shows points i can see and the yellow box shows apearing points when i zoom in.

please help.

Hello: I think your problem is the front clipping plane, one mostly unexplanined and uncontrollable "feature" we have in Metashape. All you need to do is to re-center the visualisation volume to see all points close to your point of view.  Use Doble click on one point so it becomes the new center of the world.

Agisoft, please give us a proper set of tools to take control of view clipping. Almost every 3D software provides something to allow user to manage clipping boxes or clipping planes, save them, etc.
use "filter" tool is something, is better than nothing, but is not flexible at all... is not even the right name. "filter" is more for noise removal, or to change visualisation by class.... but not to hide parts.

Hi!

Try to uncheck visible selection option in the Model menu.
