ClipUtilities Class

Static class whose various methods are functions for clipping geometry

Methods

Name Description
announceLoopsOfConvexClipPlaneSetIntersectRange(convexSet: ConvexClipPlaneSet, range: Range3d, loopFunction: (loopPoints: GrowableXYZArray) => void, includeConvexSetFaces: boolean = true, includeRangeFaces: boolean = true, ignoreInvisiblePlanes: boolean = false): void Static Emit point loops for intersection of a convex set with a range.  
announceNNC(intervals: Range1d[], cp: CurvePrimitive, announce?: AnnounceNumberNumberCurvePrimitive): boolean Static Announce triples of (low, high, cp) for each entry in intervals  
clipPolygonToClipShape(polygon: Point3d[], clipShape: ClipPrimitive): Point3d[][] Static Clip a polygon down to regions defined by each shape of a ClipShape.  
clipPolygonToClipShapeReturnGrowableXYZArrays(polygon: Point3d[], clipShape: ClipPrimitive): GrowableXYZArray[] Static Clip a polygon down to regions defined by each shape of a ClipShape.  
collectClippedCurves(curve: CurvePrimitive, clipper: Clipper): CurvePrimitive[] Static Find portions of the curve that are within the clipper.  
doesClipperIntersectRange(clipper: ConvexClipPlaneSet | UnionOfConvexClipPlaneSets | ClipPrimitive | ClipVector | undefined, range: Range3d, observeInvisibleFlag: boolean = true): boolean Static Test if various types of clippers have any intersection with a range.  
doesConvexClipPlaneSetIntersectRange(convexSet: ConvexClipPlaneSet, range: Range3d, includeConvexSetFaces: boolean = true, includeRangeFaces: boolean = true, ignoreInvisiblePlanes: boolean = false): boolean Static Emit point loops for intersection of a convex set with a range.  
loopsOfConvexClipPlaneIntersectionWithRange(convexSet: ConvexClipPlaneSet, range: Range3d, includeConvexSetFaces: boolean = true, includeRangeFaces: boolean = true, ignoreInvisiblePlanes: boolean = false): GeometryQuery[] Static Return a (possibly empty) array of geometry (Loops !!) which are facets of the intersection of the convex set intersecting a range.  
pointSetSingleClipStatus(points: GrowableXYZArray, planeSet: UnionOfConvexClipPlaneSets, tolerance: number): ClipStatus Static Given an array of points, test for trivial containment conditions.  
rangeOfClipperIntersectionWithRange(clipper: ConvexClipPlaneSet | UnionOfConvexClipPlaneSets | ClipPrimitive | ClipVector | undefined, range: Range3d, observeInvisibleFlag: boolean = true): Range3d Static Return the range of various types of clippers
ConvexClipPlaneSet -- dispatch to rangeOfConvexClipPlaneSetIntersectionWithRange
UnionOfConvexClipPlaneSet -- union of ranges of member ConvexClipPlaneSet
* ClipPrimitive -- access its UnionOfConvexClipPlaneSet.
 
rangeOfConvexClipPlaneSetIntersectionWithRange(convexSet: ConvexClipPlaneSet, range: Range3d): Range3d Static Return the (possibly null) range of the intersection of the convex set with a range.  
selectIntervals01(curve: CurvePrimitive, unsortedFractions: GrowableFloat64Array, clipper: Clipper, announce?: AnnounceNumberNumberCurvePrimitive): boolean Static Augment the unsortedFractionsArray with 0 and 1
sort
test the midpoint of each interval with clipper.isPointOnOrInside
pass accepted intervals to announce(f0,f1,curve)
