# init(position:leadingControlPoint:topControlPoint:trailingControlPoint:bottomControlPoint:) Creates a new vertex. ``` @export(implementation) init(position: SIMD2, leadingControlPoint: SIMD2, topControlPoint: SIMD2, trailingControlPoint: SIMD2, bottomControlPoint: SIMD2) ``` ## Parameters `position` the position of the vertex in the coordinate space the gradient is interpreted in. `leadingControlPoint` the Bezier control point of the vertex’s leading edge. `topControlPoint` the Bezier control point of the vertex’s top edge. `trailingControlPoint` the Bezier control point of the vertex’s trailing edge. `bottomControlPoint` the Bezier control point of the vertex’s bottom edge. --- Copyright © 2026 Apple Inc.
