new Cesium.CubeMapPanorama(options)
engine/Source/Scene/CubeMapPanorama.js 76

A Panorama that displays imagery in cube map format in a scene.

This is only supported in 3D. The cube map panorama is faded out when morphing to 2D or Columbus view. The size of the cube map panorama must not exceed Scene#maximumSkyBoxSize.

参数名称 类型 描述信息
options CubeMapPanorama.ConstructorOptions Object describing initialization options
使用示例:
const modelMatrix = Cesium.Matrix4.getMatrix3(
  Cesium.Transforms.localFrameToFixedFrameGenerator("north", "down")(
    Cesium.Cartesian3.fromDegrees(longitude, latitude, height),
    Cesium.Ellipsoid.default
  ),
  new Cesium.Matrix3()
);


scene.primitives.add(new Cesium.CubeMapPanorama({
  sources : {
    positiveX : 'cubemap_px.png',
    negativeX : 'cubemap_nx.png',
    positiveY : 'cubemap_py.png',
    negativeY : 'cubemap_ny.png',
    positiveZ : 'cubemap_pz.png',
    negativeZ : 'cubemap_nz.png'
  }
  transform: modelMatrix,
}));

成员(属性)

readonly credit : Credit
engine/Source/Scene/CubeMapPanorama.js 142

Gets the credits of the panorama.

show : boolean
engine/Source/Scene/CubeMapPanorama.js 97

Determines if the cube map panorama will be shown.
默认值: true

sources : object
engine/Source/Scene/CubeMapPanorama.js 86

The sources used to create the cube map faces: an object with positiveX, negativeX, positiveY, negativeY, positiveZ, and negativeZ properties. These can be either URLs or Image objects.
默认值: undefined

readonly transform : Matrix4
engine/Source/Scene/CubeMapPanorama.js 130

Gets the transform of the panorama.

方法

destroy()
engine/Source/Scene/CubeMapPanorama.js 342

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.

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.
使用示例:
cubeMapPanorama = cubeMapPanorama && cubeMapPanorama.destroy();
参考:

isDestroyed() → boolean
engine/Source/Scene/CubeMapPanorama.js 322

Returns true if this object was destroyed; otherwise, false.

If this object was destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception.
返回值:
true if this object was destroyed; otherwise, false.

update()
engine/Source/Scene/CubeMapPanorama.js 160

Called when Viewer or CesiumWidget render the scene to get the draw commands needed to render this primitive.

Do not call this function directly. This is documented just to list the exceptions that may be propagated when the scene is rendered:

Throws:
  • DeveloperError : this.sources is required and must have positiveX, negativeX, positiveY, negativeY, positiveZ, and negativeZ properties.
  • DeveloperError : this.sources properties must all be the same type.
