SDF Ring Segment

Inputs

float Radius | default 0.5

float Angle | default 270.0

float Thickness | default 0.2

Behaviour

Outputs the signed distance field for a ring segment, based on the provided Radius. The segment can never be a full circle, but may get very close to it. How much of the circle it covers is based on the Angle given in degrees. The Thickness parameter determines how wide the ring segment may be.
