Direct Known Subclasses:

EmbeddedTreeLineSubset3D, LineConvexSubset3D

public abstract class LineSubset3D
extends Object
implements RegionEmbedding<Vector3D,Vector1D>, Sized

Class representing a subset of a line in 3D Euclidean space. For example, line segments, rays, and disjoint combinations of the two are line subsets. Line subsets may be finite or infinite.

Method Summary

Modifier and Type	Method	Description
abstract Bounds3D	getBounds()	Get the 3D bounding box of the line subset or null if the subset is empty or infinite.
abstract Vector3D	getCentroid()	Get the centroid, or geometric center, of the line subset or null if the subset is empty or infinite.
Line3D	getLine()	Get the line containing this subset.
abstract HyperplaneBoundedRegion<Vector1D>	getSubspaceRegion()	Get the subspace region for the instance.
Vector3D	toSpace(Vector1D pt)	Transform a subspace point into a space point.
Vector1D	toSubspace(Vector3D pt)	Transform a space point into a subspace point.
