intersectSegment MethodStatic
Compute the intersection of a line (parameterized as a line segment) with the plane of this polygon.
intersectSegment(polygon: Point3d[] | IndexedXYZCollection, point0: Point3d, point1: Point3d, tolerance: number = Geometry.smallMetricDistance, result?: PolygonLocationDetail): PolygonLocationDetail
Parameter | Type | Description |
---|---|---|
polygon | Point3d[] | IndexedXYZCollection | points of the polygon, closure point optional |
point0 | Point3d | start point of segment on line to intersect |
point1 | Point3d | end point of segment on line to intersect |
tolerance | number | optional distance tolerance to determine point-vertex and point-edge coincidence. |
result | PolygonLocationDetail | optional pre-allocated object to fill and return |
Returns - PolygonLocationDetail
details d of the line-plane intersection d.point
:
d.isValid()
returns true if and only if the line intersects the plane.d.code
indicates where the intersection lies with respect to the polygon.d.a
is the segment intersection parameter. Ifd.a
is in [0,1], the segment intersects the plane of the polygon.d.edgeIndex
andd.edgeParam
specify the location of the closest point on the polygon to the intersection, withindistTol
