`Static`run

run(
    iso: (x: number, y: number) => number,
    bounds: AABB,
    cellsize: Vec2,
    quality?: number,
    subgrid?: Vec2 | null,
    combine?: boolean,
    output?: any,
): any
Run the marching squares algorithm to extract polygons from an iso function.
Parameters
- iso: (x: number, y: number) => number
  Iso function (x: number, y: number) => number. Negative values are "inside", positive are "outside".
- bounds: AABB
  AABB defining the region to extract surfaces from.
- cellsize: Vec2
  Vec2 defining cell dimensions. Auto-disposed if weak.
- quality: number = 2
  Interpolation quality (default 2). Must be >= 0.
- subgrid: Vec2 | null = null
  Optional Vec2 for sub-grid partitioning. Auto-disposed if weak.
- combine: boolean = true
  Whether to combine adjacent polygons (default true).
- output: any = null
  Optional GeomPolyList to populate. If null, a new one is created.
Returns any
The populated GeomPolyList.
