facetRegionXY MethodStatic
Facet the region according to stroke options.
facetRegionXY(region: AnyRegion, options?: StrokeOptions): undefined | IndexedPolyface
@note For best results, UnionRegion input should consist of non-overlapping children. See regionBooleanXY.
@note For best results, ParityRegion input should be correctly oriented. See sortOuterAndHoleLoopsXY.
@returns facets for the region, or undefined if facetting failed
| Parameter | Type | Description |
|---|---|---|
| region | AnyRegion | a closed xy-planar region, possibly with holes. * The z-coordinates of the region are ignored. Caller is responsible for rotating the region into plane local coordinates beforehand, and reversing the rotation afterwards. |
| options | StrokeOptions | primarily how to stroke the region boundary, but also how to facet the region interior. * By default, a triangulation is returned, but if options.maximizeConvexFacets === true, edges between coplanar triangles are removed to return maximally convex facets. |
Returns - undefined | IndexedPolyface
