We are glad to announce that the Circle2 and Arc2 types have been added to the RCGAL. The Circle2 type represents a circle, and the Arc2 type represents an arc of a circle. The old Segment2 type has been renamed to LineSegment2, and the Segment2 trait has been added.

The Location and Intersection of the Circle2 and Arc2 types have been implemented.

We optimized the Intersection, you can get check if two segments intersect through the is_segment_2_segment_2_intersected function, and get the intersection point through the segment_2_segment_2_intersection function, no matter the segments are lines, circles, or arcs.

The sweep_line_segment_2_intersection function has been removed, and the sweep_segment_2_intersection function has been added. You can get the intersection points of a bunch of segments, no matter the segments are lines, circles, or arcs.

Thanks for your interest in the RCGAL, and I hope we can learn and grow together.
