public abstract class LineConvexSubset3D
extends LineSubset3D

Class representing a convex subset of a line in 3D Euclidean space. Instances need not be finite, in which case the start or end point (or both) will be null.

Method Details

getStartPoint

public abstract Vector3D getStartPoint()

Get the start point for the line subset.

Returns:

the start point for the line subset, or null if no start point exists

getSubspaceStart

public abstract double getSubspaceStart()

Get the 1D start location of the line subset or Double.NEGATIVE_INFINITY if no start location exists.

Returns:

the 1D start location of the line subset or Double.NEGATIVE_INFINITY if no start location exists.

getEndPoint

public abstract Vector3D getEndPoint()

Get the end point for the line subset.

Returns:

the end point for the line subset, or null if no end point exists.

getSubspaceEnd

public abstract double getSubspaceEnd()

Get the 1D end location of the line subset or Double.POSITIVE_INFINITY if no end location exists.

Returns:

the 1D end location of the line subset or Double.POSITIVE_INFINITY if no end location exists

getSubspaceRegion

public Interval getSubspaceRegion()

Get the subspace region for the instance.

Specified by:

getSubspaceRegion in interface RegionEmbedding<Vector3D,Vector1D>

Specified by:

getSubspaceRegion in class LineSubset3D

Returns:

the subspace region for the instance

getInterval

public Interval getInterval()

Get the 1D interval for the line subset. This method is an alias for getSubspaceRegion().

Returns:

the 1D interval for the line subset.

contains

public boolean contains(Vector3D pt)

Return true if the given point lies in the line subset.

Parameters:

pt - point to check

Returns:

true if the point lies in the line subset

transform

public abstract LineConvexSubset3D transform(Transform<Vector3D> transform)

Transform this instance.

Parameters:

transform - the transform to apply

Returns:

a new, transformed instance
