computePlanePlanePlaneIntersections Method

Compute intersections among all combinations of 3 planes in the convex set.

  • optionally throw out points that are not in the set.
  • optionally push the points in the caller-supplied point array.
  • optionally extend a caller supplied range.
  • In the common case where the convex set is (a) a slab or (b) a view frustum, there will be 8 points and the range is the range of the convex set.
  • If the convex set is unbounded, the range only contains the range of the accepted (corner) points, and the range is not a representative of the "range of all points in the set" .

computePlanePlanePlaneIntersections(points: undefined | Point3d[], rangeToExtend: undefined | Range3d, transform?: Transform, testContainment: boolean = true): number

Parameter Type Description
points undefined | Point3d[] (optional) array to which computed points are to be added.
rangeToExtend undefined | Range3d  
transform Transform (optional) transform to apply to the points.
testContainment boolean if true, test each point to see if it is within the convex set. (Send false if confident that the convex set is rectilinear set such as a slab. Send true if chiseled corners are possible)

Returns - number

number of points.
