Class PolygonalBoolean¶

import { PolygonalBoolean } from 'scenerystack/alpenglow';

Static Methods¶

union( ...paths : RenderPath[] ) : Vector2[][]¶

intersection( ...paths : RenderPath[] ) : Vector2[][]¶

difference( pathA : RenderPath, pathB : RenderPath ) : Vector2[][]¶

getOverlaps( pathA : RenderPath, pathB : RenderPath ) : { intersection: Vector2[][]; aOnly: Vector2[][]; bOnly: Vector2[][] }¶

cag( paths : RenderPath[], getFaceData : ( face: RationalFace ) => FaceData, createOutputFace : ( face: PolygonalFace, faceData: FaceData, bounds: Bounds2 ) => OutputFace, isFaceDataCompatible : ( faceData1: FaceData, faceData2: FaceData | null ) => boolean, log : RasterTileLog | null ) : OutputFace[]¶

TODO: ideally handle the fully collinear simplification?
