fromFilletedLineString MethodStatic

Extract points and radii from a valid filleted linestring.

• A valid filleted linestring is a CurveChain that satisfies the following conditions:
  • Its children have type Arc3d, LineSegment3d, or LineString3d.
  • Each Arc3d is circular.
  • Each Arc3d sweep is less than 180 degrees.
  • Each Arc3d cannot be adjacent to another Arc3d.
  • Each Arc3d is G1 continuous with each of its neighbors, i.e., at their common point, the curves have the same tangent direction.
• To treat more input chains as valid, pass options.relaxedValidation = true. Internally, this setting performs several transformations on the input to produce a valid filleted linestring:
  • Arc3ds with large sweep are uniformly split into 2 or 3 smaller arcs to improve the proximity of their PI points (cf. computeTangentIntersection). Arcs with sweep greater than 360 degrees are not allowed.
  • Adjacent Arc3ds are separated by a zero-length LineSegment3d.
  • An Arc3d that is not G1 continuous with its linear neighbor is separated from it by a zero-length LineSegment3d to preserve the corner.

fromFilletedLineString(filletedLineString: CurveChain, options?: FilletedLineStringOptions): [Point3d, number][] | undefined

@returns Array of [point, radius] pairs extracted from input, or undefined if the input is not valid. A radius of zero means no fillet at the vertex.

Returns - [Point3d, number][] | undefined

Array of [point, radius] pairs extracted from input, or undefined if the input is not valid. A radius of zero means no fillet at the vertex.
