From what I understand any boost geometry
is fully closed. Is there a way of making a geometry half
closed, such that the bottom row is not included?
I’m needing to do this with a Box2D$Values.
Any help appreciated.
No, this is not really implemented. Which problem do you have in
mind? For example a "touch" relationship where two geometries touch
each other, would this differ if they touch the upper row instead of
the lower row?
The within-algorithm (for point-in-box) considers a point within if
it is completely inside. That can be finetuned by supplying a
strategy which considers bottom-row / right row.
