[name]

A geometric line segment represented by a start and end point.

Constructor

[name]([param:Vector3 start], [param:Vector3 end])

[page:Vector3 start] - Start of the line segment. Default is (0, 0, 0).
[page:Vector3 end] - End of the line segment. Default is (0, 0, 0).

Creates a new [name].

Properties

[property:Vector3 start]

[page:Vector3] representing the start point of the line.

[property:Vector3 end]

[page:Vector3] representing the end point of the line.

Methods

[method:Line3 applyMatrix4]([param:Matrix4 matrix])

Applies a matrix transform to the line segment.

[method:Vector3 at]([param:Float t], [param:Vector3 target])

[page:Float t] - Use values 0-1 to return a position along the line segment.
[page:Vector3 target] — the result will be copied into this Vector3.

Returns a vector at a certain position along the line. When [page:Float t] = 0, it returns the start vector, and when [page:Float t] = 1 it returns the end vector.

[method:Line3 clone]()

Returns a new [page:Line3] with the same [page:.start start] and [page:.end end] vectors as this one.

[method:Vector3 closestPointToPoint]([param:Vector3 point], [param:Boolean clampToLine], [param:Vector3 target])

[page:Vector3 point] - return the closest point on the line to this point.
[page:Boolean clampToLine] - whether to clamp the returned value to the line segment.
[page:Vector3 target] — the result will be copied into this Vector3.

Returns the closets point on the line. If [page:Boolean clampToLine] is true, then the returned value will be clamped to the line segment.

[method:Float closestPointToPointParameter]([param:Vector3 point], [param:Boolean clampToLine])

[page:Vector3 point] - the point for which to return a point parameter.
[page:Boolean clampToLine] - Whether to clamp the result to the range [0, 1].

Returns a point parameter based on the closest point as projected on the line segement. If [page:Boolean clampToLine] is true, then the returned value will be between 0 and 1.

[method:Line3 copy]([param:Line3 line])

Copies the passed line's [page:.start start] and [page:.end end] vectors to this line.

[method:Vector3 delta]([param:Vector3 target])

[page:Vector3 target] — the result will be copied into this Vector3.

Returns the delta vector of the line segment ([page:.end end] vector minus the [page:.start start] vector).

[method:Float distance]()

Returns the [link:https://en.wikipedia.org/wiki/Euclidean_distance Euclidean distance] (straight-line distance) between the line's [page:.start start] and [page:.end end] points.

[method:Float distanceSq]()

Returns the square of the [link:https://en.wikipedia.org/wiki/Euclidean_distance Euclidean distance] (straight-line distance) between the line's [page:.start start] and [page:.end end] vectors.

[method:Boolean equals]([param:Line3 line])

[page:Line3 line] - [page:Line3] to compare with this one.

Returns true if both line's [page:.start start] and [page:.end en] points are equal.

[method:Vector3 getCenter]([param:Vector3 target])

[page:Vector3 target] — the result will be copied into this Vector3.

Returns the center of the line segment.

[method:Line3 set]([param:Vector3 start], [param:Vector3 end])

[page:Vector3 start] - set the [page:.start start point] of the line.
[page:Vector3 end] - set the [page:.end end point] of the line.

Sets the start and end values by copying the provided vectors.
