Is there a way to “unpick”
data that was previously “picked”?

The issue is that pick, is very precise.
I cannot depend on a identical click, in the exact same location, to create
the “unpick” tool and behavior that I am looking for.

It occurs to me that it is possible
to create an “unpick” event by creating a matrix of data that
surrounds the unpick location and then if the picked data point is within
this matrix of data, I can process and remove the originally picked point
from the location I am storing the original pick locations.

Maybe Pygame or a collision tool might
work also, but I have to study to find out.

Is there another preferred way that
you see? or can recommend?

Thank You and Best Regards,
