方法

static Cesium.AxisAlignedBoundingBox.clone(box, result) → AxisAlignedBoundingBox
engine/Source/Core/AxisAlignedBoundingBox.js 146

Duplicates a AxisAlignedBoundingBox instance.
参数名称 类型 描述信息
box AxisAlignedBoundingBox The bounding box to duplicate.
result AxisAlignedBoundingBox 可选 The object onto which to store the result.
返回值:
The modified result parameter or a new AxisAlignedBoundingBox instance if none was provided. (Returns undefined if box is undefined)

static Cesium.AxisAlignedBoundingBox.equals(left, right) → boolean
engine/Source/Core/AxisAlignedBoundingBox.js 169

Compares the provided AxisAlignedBoundingBox componentwise and returns true if they are equal, false otherwise.
参数名称 类型 描述信息
left AxisAlignedBoundingBox 可选 The first AxisAlignedBoundingBox.
right AxisAlignedBoundingBox 可选 The second AxisAlignedBoundingBox.
返回值:
true if left and right are equal, false otherwise.

static Cesium.AxisAlignedBoundingBox.fromCorners(minimum, maximum, result) → AxisAlignedBoundingBox
engine/Source/Core/AxisAlignedBoundingBox.js 60

Creates an instance of an AxisAlignedBoundingBox from its corners.
参数名称 类型 描述信息
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 可选 The object onto which to store the result.
返回值:
The modified result parameter or a new AxisAlignedBoundingBox instance if one was not provided.
使用示例:
// 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));

static Cesium.AxisAlignedBoundingBox.fromPoints(positions, result) → AxisAlignedBoundingBox
engine/Source/Core/AxisAlignedBoundingBox.js 89

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.
参数名称 类型 描述信息
positions Array.<Cartesian3> List of points that the bounding box will enclose. Each point must have a x, y, and z properties.
result AxisAlignedBoundingBox 可选 The object onto which to store the result.
返回值:
The modified result parameter or a new AxisAlignedBoundingBox instance if one was not provided.
使用示例:
// 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)]);

static Cesium.AxisAlignedBoundingBox.intersectPlane(box, plane) → Intersect
engine/Source/Core/AxisAlignedBoundingBox.js 191

Determines which side of a plane a box is located.
参数名称 类型 描述信息
box AxisAlignedBoundingBox The bounding box to test.
plane Plane The plane to test against.
返回值:
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.

clone(result) → AxisAlignedBoundingBox
engine/Source/Core/AxisAlignedBoundingBox.js 232

Duplicates this AxisAlignedBoundingBox instance.
参数名称 类型 描述信息
result AxisAlignedBoundingBox 可选 The object onto which to store the result.
返回值:
The modified result parameter or a new AxisAlignedBoundingBox instance if one was not provided.

equals(right) → boolean
engine/Source/Core/AxisAlignedBoundingBox.js 256

Compares this AxisAlignedBoundingBox against the provided AxisAlignedBoundingBox componentwise and returns true if they are equal, false otherwise.
参数名称 类型 描述信息
right AxisAlignedBoundingBox 可选 The right hand side AxisAlignedBoundingBox.
返回值:
true if they are equal, false otherwise.

intersectPlane(plane) → Intersect
engine/Source/Core/AxisAlignedBoundingBox.js 245

Determines which side of a plane this box is located.
参数名称 类型 描述信息
plane Plane The plane to test against.
返回值:
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.
