new Cesium.EquirectangularPanorama(options)
engine/Source/Scene/EquirectangularPanorama.js 70

A Panorama that displays imagery in equirectangular format in a scene.
参数名称 类型 描述信息
options EquirectangularPanorama.ConstructorOptions Object describing initialization options
使用示例:
const position = Cesium.Cartesian3.fromDegrees(
  -75.1699,  // longitude
  39.9522,   // latitude
  100.0      // height in meters
);

const heading = Cesium.Math.toRadians(45.0); // rotation about up axis
const pitch = Cesium.Math.toRadians(-30.0);   // pitch (negative looks down)
const roll = Cesium.Math.toRadians(10.0);    // roll about forward axis

const hpr = new Cesium.HeadingPitchRoll(
  heading,
  pitch,
  roll
);

const modelMatrix = Cesium.Transforms.headingPitchRollToFixedFrame(
  position,
  hpr,
  Cesium.Ellipsoid.WGS84,
  Cesium.Transforms.eastNorthUpToFixedFrame
);

scene.primitives.add(new Cesium.EquirectangularPanorama({
  transform: modelMatrix,
  image: 'path/to/image',
}));

成员(属性)

readonly credit : Credit
engine/Source/Scene/EquirectangularPanorama.js 185

Gets the credits of the panorama.

readonly image : string|HTMLImageElement|HTMLCanvasElement|ImageBitmap
engine/Source/Scene/EquirectangularPanorama.js 161

Gets the source image of the panorama.

方法

destroy()
engine/Source/Scene/EquirectangularPanorama.js 243

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:
equirectangularPanorama = equirectangularPanorama && equirectangularPanorama.destroy();
参考:

isDestroyed() → boolean
engine/Source/Scene/EquirectangularPanorama.js 259

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.
参考:

update()
engine/Source/Scene/EquirectangularPanorama.js 219

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:
