| Jul 11 at 13:15 | comment | added | Markus von Broady | Now remove remaining points inside circles, sort points by Gradient: radial positioned at the average of two circles centers (or average of two intersections), and convert those points to curve and then fill the curve. You don't even need to fill you can just spawn a new mesh circle with the number of points of the remaining points of the 2 circles (after deleting those inside) just remember to merge by distance before counting them or disregard the doubled points that were inside but were moved to intersections. | |
| Jul 11 at 13:15 | comment | added | Markus von Broady | For efficient coplanar circle joining you can store selection of vertices of mesh circles calculated based on being inside the other circle (which is trivial, it's based on the distance to the other circle being less than its radius). If you store that as float, then the edge having interpolated 0.5 value is the edge that intersects that circle. Then you can use an intersection algorithm to find where to move the vertex that is inside the other circle. | |
