KBE3D / KBCore / Cesium / DebugModelMatrixPrimitive

类: DebugModelMatrixPrimitive

Draws the axes of a reference frame defined by a matrix that transforms to world coordinates, i.e., Earth's WGS84 coordinates. The most prominent example is a primitives <code>modelMatrix</code>. <p> The X axis is red; Y is green; and Z is blue. </p> <p> This is for debugging only; it is not optimized for production use. </p>

示例

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

参数

Object with the following properties:

参数

The length of the axes in meters.

参数

The width of the axes in pixels.

参数

The 4x4 matrix that defines the reference frame, i.e., origin plus axes, to visualize.

参数

Determines if this primitive will be shown.

参数

A user-defined object to return when the instance is picked with Scene#pick

属性

length

length: number

The length of the axes in meters.

---

width

width: number

The width of the axes in pixels.

---

show

show: boolean

Determines if this primitive will be shown.

---

modelMatrix

modelMatrix: Matrix4

The 4x4 matrix that defines the reference frame, i.e., origin plus axes, to visualize.

---

id

id: any

User-defined value returned when the primitive is picked.

方法

isDestroyed()

isDestroyed(): boolean

Returns true if this object was destroyed; otherwise, false. <p> If this object was destroyed, it should not be used; calling any function other than <code>isDestroyed</code> will result in a DeveloperError exception. </p>

返回

boolean

true if this object was destroyed; otherwise, false.

---

destroy()

destroy(): void

Destroys the WebGL resources held by this object. Destroying an object allows for deterministic release of WebGL resources, instead of relying on the garbage collector to destroy this object. <p> Once an object is destroyed, it should not be used; calling any function other than <code>isDestroyed</code> will result in a DeveloperError exception. Therefore, assign the return value (<code>undefined</code>) to the object as done in the example. </p>

返回

void

示例

p = p && p.destroy();
