Box

Kotlin |Java

abstract class Box

Known direct subclasses

ImmutableBox, MutableBox

`ImmutableBox`	An immutable axis-aligned rectangle.
`MutableBox`	A mutable axis-aligned rectangle.

Represents an axis-aligned rectangle. See ImmutableBox and MutableBox for concrete classes implementing Box.

The Box interface is the read-only view of the underlying data which may or may not be mutable.

Summary

Public functions
`MutableVec`	`computeCenter(outVec: MutableVec)` Populates `outVec` with the center of the `Box`, and returns `outVec`.
`Unit`	`computeCorners( outVecXMinYMin: MutableVec, outVecXMaxYMin: MutableVec, outVecXMaxYMax: MutableVec, outVecXMinYMax: MutableVec )` Populates the 4 output points with the corners of the `Box`.
`operator Boolean`	`contains(otherBox: Box)` Returns whether the other Box is contained within this Box.
`operator Boolean`	`contains(point: Vec)` Returns whether the given point is contained within the Box.
`Boolean`	`isAlmostEqual(other: Box, tolerance: @FloatRange(from = 0.0) Float)` Compares this `Box` with `other`, and returns true if the difference between `xMin` and other.xMin is less than `tolerance`, and likewise for `xMax`, `yMin`, and `yMax`.

Public properties
`Float`	`height` The height of the rectangle.
`Float`	`width` The width of the rectangle.
`abstract Float`	`xMax` The upper bound in the `X` direction.
`abstract Float`	`xMin` The lower bound in the `X` direction.
`abstract Float`	`yMax` The upper bound in the `Y` direction.
`abstract Float`	`yMin` The lower bound in the `Y` direction.

Public functions

computeCenter

Added in 1.0.0-alpha04

fun computeCenter(outVec: MutableVec): MutableVec

Populates outVec with the center of the Box, and returns outVec.

computeCorners

Added in 1.0.0-alpha04

fun computeCorners(
    outVecXMinYMin: MutableVec,
    outVecXMaxYMin: MutableVec,
    outVecXMaxYMax: MutableVec,
    outVecXMinYMax: MutableVec
): Unit

Populates the 4 output points with the corners of the Box. The order of the corners is: (x_min, y_min), (x_max, y_min), (x_max, y_max), (x_min, y_max)

contains

Added in 1.0.0-alpha04

operator fun contains(otherBox: Box): Boolean

Returns whether the other Box is contained within this Box. Edges of the other Box that overlap with this one's boundary are considered to be contained.

contains

Added in 1.0.0-alpha04

operator fun contains(point: Vec): Boolean

Returns whether the given point is contained within the Box. Points that lie exactly on the Box's boundary are considered to be contained.

isAlmostEqual

Added in 1.0.0-alpha04

fun isAlmostEqual(other: Box, tolerance: @FloatRange(from = 0.0) Float): Boolean

Compares this Box with other, and returns true if the difference between xMin and other.xMin is less than tolerance, and likewise for xMax, yMin, and yMax.
