Class: OffsetCurve2d ​

Defined in: curve2d/OffsetCurve2d.ts:19

Offset 2D curve: basis curve displaced by a constant distance along the left normal. Mirrors Geom2d_OffsetCurve.

P_offset(t) = P_base(t) + distance * N(t) where N(t) = (-tangent.y, tangent.x) (left normal, 90° CCW from tangent). distance > 0 = left side (CCW offset), distance < 0 = right side.
