SweepContour Class
Sweepable planar contour with Transform for local to world interaction.
- The surface/solid classes
LinearSweep
,RotationalSweep
,RuledSweep
use this for their swept contours.
Methods
Name | Description | |

announceFacets(announce: (facets: IndexedPolyface) => void, options?: StrokeOptions): void | Emit facets to a function | |
buildFacets(options?: StrokeOptions): void | Build the (cached) internal facets for the contour. | |
clone(): SweepContour | Return a deep clone. | |
cloneTransformed(transform: Transform): undefined | SweepContour | Return a transformed clone. | |
computeXYStrokes(options?: StrokeOptions): void | Recompute the local strokes cache for this contour | |
emitFacets(builder: PolyfaceBuilder, reverse: boolean, transform?: Transform): void | Emit facets to a builder. | |
getCurves(): CurveCollection | Return (Reference to) the curves | |
isAlmostEqual(other: any): boolean | Test for near equality of curves, frame, and axis. | |
purgeFacets(): void | Delete facet cache. | |
sweepToUnionOfConvexClipPlaneSets(sweepVector?: Vector3d, cap0: booleanfalse, cap1: booleanfalse, options?: StrokeOptions): undefined | UnionOfConvexClipPlaneSets | Create a UnionOfConvexClipPlaneSets that clips to the swept faceted contour region. | |
tryTransformInPlace(transform: Transform): boolean | Apply transform to the curves, axis. |
|
createForLinearSweep(contour: AnyCurve, defaultNormal?: Vector3d): undefined | SweepContour Static | Create for linear sweep. | |
