Shapemetry API / Circle2d

Class: Circle2d ​

Defined in: curve2d/Circle2d.ts:23

Circle arc in 2D, ported from Geom2d_Circle + Geom2d_TrimmedCurve.

Parametrization: P(t) = center + radius * cos(startAngle + sweepAnglet) * (1,0) + radius * sin(startAngle + sweepAnglet) * (0,1) t ∈ [0, 1]

sweepAngle > 0 = CCW, sweepAngle < 0 = CW. Full circle: sweepAngle = ±2π.
