DebugModelMatrixPrimitive - CesiumJS API 文档

new Cesium.DebugModelMatrixPrimitive(options)

绘制向世界转换的矩阵定义的参考框架轴坐标, i.e . 地球的 WGS84 坐标. 最突出的例子是 a原始人 NT 0 模范Matrix NT 1 .

X轴为红色;Y为绿色;Z为蓝色.

仅用于调试;不优化用于生产.

Name Type Description

options

object

optional 下列属性的对象 :

Name	Type	Default	Description
`length`	number	`10000000.0`	optional The length of the axes in meters.
`width`	number	`2.0`	optional 轴的宽度以像素表示.
`modelMatrix`	Matrix4	`Matrix4.IDENTITY`	optional The 4x4 matrix that defines the reference frame, i.e., origin plus axes, to visualize.
`show`	boolean	`true`	optional Determines if this primitive will be shown.
`id`	object		optional A user-defined object to return when the instance is picked with `Scene#pick`

Example:

primitives.add(new Cesium.DebugModelMatrixPrimitive({
  modelMatrix : primitive.modelMatrix,  // primitive to debug
  length : 100000.0,
  width : 10.0
}));

Members

id : *

选择原始时返回用户定义的值 .

Default Value: undefined

See:

Scene#pick

length : number

斧头的长度以米计.

Default Value: 10000000.0

modelMatrix : Matrix4

定义参考框架的4x4矩阵 i.e .,来源加轴,可视化.

Default Value: Matrix4.IDENTITY

show : boolean

确定是否将显示此原始文件 .

Default Value: true

width : number

轴的宽度以像素表示.

Default Value: 2.0

Methods

destroy()

Destroys the WebGL resources held by this object. Destroying an object allows for deterministic 释放 WebGL 资源,而不是依赖垃圾收集器来摧毁此对象.

Once an object is destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception. Therefore, assign the return value (undefined) to the object as done in the example.

Throws:

DeveloperError : This object was destroyed, i.e., destroy() was called.

Example:

p = p && p.destroy();

See:

DebugModelMatrixPrimitive#isDestroyed

isDestroyed() → boolean

如果此对象被销毁, 返回真实; 否则, 错误 .

If this object was destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception.

Returns:

true if this object was destroyed; otherwise, false.
