类: AxisAlignedBoundingBox

Creates an instance of an AxisAlignedBoundingBox from the minimum and maximum points along the x, y, and z axes.

参数

The minimum point along the x, y, and z axes.

参数

The maximum point along the x, y, and z axes.

参数

The center of the box; automatically computed if not supplied.

属性

minimum

minimum: Cartesian3

The minimum point defining the bounding box.

---

maximum

maximum: Cartesian3

The maximum point defining the bounding box.

---

center

center: Cartesian3

The center point of the bounding box.

方法

fromCorners()

static fromCorners(minimum: Cartesian3, maximum: Cartesian3, result?: AxisAlignedBoundingBox): AxisAlignedBoundingBox

Creates an instance of an AxisAlignedBoundingBox from its corners.

参数

minimum

Cartesian3

The minimum point along the x, y, and z axes.

maximum

Cartesian3

The maximum point along the x, y, and z axes.

result?

AxisAlignedBoundingBox

The object onto which to store the result.

返回

AxisAlignedBoundingBox

The modified result parameter or a new AxisAlignedBoundingBox instance if one was not provided.

示例

// Compute an axis aligned bounding box from the two corners.
const box = Cesium.AxisAlignedBoundingBox.fromCorners(new Cesium.Cartesian3(-1, -1, -1), new Cesium.Cartesian3(1, 1, 1));

---

fromPoints()

static fromPoints(positions: Cartesian3[], result?: AxisAlignedBoundingBox): AxisAlignedBoundingBox

Computes an instance of an AxisAlignedBoundingBox. The box is determined by finding the points spaced the farthest apart on the x, y, and z axes.

参数

positions

Cartesian3[]

List of points that the bounding box will enclose. Each point must have a <code>x</code>, <code>y</code>, and <code>z</code> properties.

result?

AxisAlignedBoundingBox

The object onto which to store the result.

返回

AxisAlignedBoundingBox

The modified result parameter or a new AxisAlignedBoundingBox instance if one was not provided.

示例

// Compute an axis aligned bounding box enclosing two points.
const box = Cesium.AxisAlignedBoundingBox.fromPoints([new Cesium.Cartesian3(2, 0, 0), new Cesium.Cartesian3(-2, 0, 0)]);

---

clone()

static clone(box: AxisAlignedBoundingBox, result?: AxisAlignedBoundingBox): AxisAlignedBoundingBox

Duplicates a AxisAlignedBoundingBox instance.

参数

box

AxisAlignedBoundingBox

The bounding box to duplicate.

result?

AxisAlignedBoundingBox

The object onto which to store the result.

返回

AxisAlignedBoundingBox

The modified result parameter or a new AxisAlignedBoundingBox instance if none was provided. (Returns undefined if box is undefined)

---

equals()

static equals(left?: AxisAlignedBoundingBox, right?: AxisAlignedBoundingBox): boolean

Compares the provided AxisAlignedBoundingBox componentwise and returns <code>true</code> if they are equal, <code>false</code> otherwise.

参数

left?

AxisAlignedBoundingBox

The first AxisAlignedBoundingBox.

right?

AxisAlignedBoundingBox

The second AxisAlignedBoundingBox.

返回

boolean

true if left and right are equal, false otherwise.

---

intersectPlane()

static intersectPlane(box: AxisAlignedBoundingBox, plane: Plane): Intersect

Determines which side of a plane a box is located.

参数

box

AxisAlignedBoundingBox

The bounding box to test.

plane

Plane

The plane to test against.

返回

Intersect

Intersect.INSIDE if the entire box is on the side of the plane the normal is pointing, Intersect.OUTSIDE if the entire box is on the opposite side, and Intersect.INTERSECTING if the box intersects the plane.

---

intersectAxisAlignedBoundingBox()

static intersectAxisAlignedBoundingBox(box: AxisAlignedBoundingBox, other: AxisAlignedBoundingBox): boolean

Determines whether two axis aligned bounding boxes intersect.

参数

box

AxisAlignedBoundingBox

first box

other

AxisAlignedBoundingBox

second box

返回

boolean

true if the boxes intersect; otherwise, false.

---

clone()

clone(result?: AxisAlignedBoundingBox): AxisAlignedBoundingBox

Duplicates this AxisAlignedBoundingBox instance.

参数

result?

AxisAlignedBoundingBox

The object onto which to store the result.

返回

AxisAlignedBoundingBox

The modified result parameter or a new AxisAlignedBoundingBox instance if one was not provided.

---

intersectPlane()

intersectPlane(plane: Plane): Intersect

Determines which side of a plane this box is located.

参数

plane

Plane

The plane to test against.

返回

Intersect

Intersect.INSIDE if the entire box is on the side of the plane the normal is pointing, Intersect.OUTSIDE if the entire box is on the opposite side, and Intersect.INTERSECTING if the box intersects the plane.

---

intersectAxisAlignedBoundingBox()

intersectAxisAlignedBoundingBox(other: AxisAlignedBoundingBox): boolean

Determines whether some other axis aligned bounding box intersects this box.

参数

other

AxisAlignedBoundingBox

The other axis aligned bounding box.

返回

boolean

true if the boxes intersect; otherwise, false.

---

equals()

equals(right?: AxisAlignedBoundingBox): boolean

Compares this AxisAlignedBoundingBox against the provided AxisAlignedBoundingBox componentwise and returns <code>true</code> if they are equal, <code>false</code> otherwise.

参数

right?

AxisAlignedBoundingBox

The right hand side AxisAlignedBoundingBox.

返回

boolean

true if they are equal, false otherwise.
