rectangleEdgeTransform MethodStatic

Test if data is one of several forms of a rectangle.

• If so, return transform with
  • origin at one corner
  • x and y columns extend along two adjacent sides
  • z column is unit normal.
• The recognized data forms for simple analysis of points are:
  • LineString
  • Loop containing rectangle content
  • Path containing rectangle content
  • Array of Point3d[]
  • IndexedXYZCollection
• Points are considered a rectangle if
  • Within the first 4 points
    • vectors from 0 to 1 and 0 to 3 are perpendicular and have a non-zero cross product
    • vectors from 0 to 3 and 1 to 2 are the same
  • optionally require a 5th point that closes back to point0
  • If there are other than the basic number of points (4 or 5) the data

rectangleEdgeTransform(data: AnyCurve | Point3d[] | IndexedXYZCollection, requireClosurePoint: boolean = true): Transform | undefined
