Points visualization sizes does not reduce with version v2020.09 shipped with Debian Bullseye #1076

Open jcr4p opened 3 years ago

jcr4p commented 3 years ago

Opening the attached file, the points in the point cloud does not reduce their size within an acceptable dimension. The problem is reproducible using either alt+wheel or "Point Size" slide bar.

Using version: 2020.09 (official version in Debian 11 "bullseye" version) OS: debian bullseye with KDE but also with gnome.

The issue is actually caused that one single spurious point that makes the bounding box big such that there is no way to compute proper values for the point size slidebar. Just deleting the spurious point solves the issue.

Hi, thank you for the quick answer! This is just an example, there are other cases with big point cloud (with big bounding box) which have the same problem. The versions in stretch or buster repositories does not have this issue. We work with such point clouds very often and meshlab was fantastic for these cases.

Isn't there any workaround for this ? Maybe ignoring the slide bar in case of very extended point clouds? It's a pity for us not be able to use the latest meshlab features for this vizualization problem.

Thank you for your time

Right now there are no workarounds... I can try to figure out if there is something I can do to have this working properly for all the cases!

Thank you very much!

Couldn't you just allow us to set an absolute point size, regardless of the bounding box size?
