Average​Plane

public method AveragePlane → ()

returns → Plane

The average plane.

Computes an average plane for the given points.

Bounding​Box

public method BoundingBox → ()

returns → Box3D

The axis-aligned bounding box.

Computes the smallest axis-aligned bounding box that contains all points.

Bounding​Cuboid

public method BoundingCuboid → ()

returns → Cuboid

The bounding cuboid.

Computes a bounding cuboid aligned to the principal axes that contain all points.

Bounding​Sphere

public method BoundingSphere → ()

returns → Sphere

The bounding sphere.

Computes a non-minimal bounding sphere that contains all points.

This method uses Ritter’s algorithm:

Clear

public method Clear → ()

Clears all points from the list.

Get

public method Get → (1)

idx in : int32

[0..Points.Count-1]
The point index.

returns → Vec3D

The point coordinates.

Returns the idx in-th point, as it has been added (without weight).

public method MeanPosition → ()

returns → Vec3D

The mean point position.

Computes the mean point position.

Principal​Axis

public method PrincipalAxis → (1)

n in : int32

[0..2]
The axis to return (0 : most significant, 2 : least significant).

returns → Vec3D

The unit-length principal axis vector.

Returns the principal axis of the points.

Public / Attributes

Count

public attribute Count → (get)

value : int32

[>=0]
The number of points.

Returns the number of points in the list.
