The face to test the points against.
The points to sort.
OptionaltoleranceHow close to the boundary a point may be to count as on it, in model units.
OptionaluseWhen true, a point outside the face's bounding box, grown by gapTolerance, counts as
outside without the exact test; a quick reject for many points far from the face.
OptionalgapHow far beyond the bounding box a point may lie and still get the exact test when
useBndBox is on, in model units.
OptionalkeepWhen true, points inside the face are kept.
OptionalkeepWhen true, points on the boundary of the face are kept.
OptionalkeepWhen true, points outside the face are kept.
OptionalkeepWhen true, points the kernel cannot place inside, on or outside the face are kept.
A face, points and which groups to keep for
shapes.face.filterFacePoints, which sorts each point as inside, on the boundary of or outside the face.
