Hey @emilk first time contributor here. Can I take this up? Any pointers would be awesome

[emilk]

@meehawk sorry for the slow reply - I missed your comment!

There are at least two things to fix here:

• Input-validation: the Python SDK should log a warning (_send_warning) when users use a negative radius
• The viewer should never ever crash, so we should also in the viewer log a warning with re_log::warn_once and then do some sane fallback, like ignoring the point.
