https://doc.cdryx.net/CdryxAIOUPlugin/ccoreumodule/geometry/index.html Overview Core geometry primitives used across all modules for spatial computation: circles, edges, polygons, rectangles, triangles, tiles, splines, Delaunay triangulation, Voronoi diagrams, MST, noise and visual effects. FCCircle Simple 2D circle defined by center and radius. Name Description center FVector2D center position radius Circle radius (default 1.0) pointInside Returns true if a point is inside the circle (distance² ≤ radius²) FCCircle circle(FVector2D(100, 200), 500.0f); bool inside = circle.pointInside(FVector2D(150, 250));FCEdge 2D line segment with index, width, and spatial query functions.
