CircleGeometry is a simple shape of Euclidean geometry. It is constructed from a number of triangular segments that are oriented around a central point and extend as far out as a given radius. It is built counter-clockwise from a start angle and a given central angle. It can also be used to create regular polygons, where the number of segments determines the number of sides.
const geometry = new v3d.CircleGeometry(5, 32);
const material = new v3d.MeshBasicMaterial({ color: 0xffff00 });
const circle = new v3d.Mesh(geometry, material);
scene.add(circle);
radius — Radius of the circle, default = 1.
segments — Number of segments (triangles), minimum = 3, default = 32.
thetaStart — Start angle for first segment, default = 0 (three o'clock position).
thetaLength — The central angle, often called theta, of the circular sector. The default is 2*Pi, which makes for a complete circle.
