KBE3D / KBCore / Cesium / EquirectangularPanorama

类: EquirectangularPanorama

A Panorama that displays imagery in equirectangular format in a scene.

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',
}));

参数

Object describing initialization options

属性

radius

readonly radius: number

Gets the radius of the panorama.

---

image

readonly image: string | HTMLCanvasElement | HTMLImageElement | ImageBitmap

Gets the source image of the panorama.

---

transform

readonly transform: Matrix4

Gets the transform of the panorama.

---

credit

readonly credit: Credit

Gets the credits of the panorama.

---

show

show: boolean

Determines if the equirectangular panorama will be shown.

方法

update()

update(): void

Called when Viewer or CesiumWidget render the scene to get the draw commands needed to render this primitive. <p> Do not call this function directly. This is documented just to list the exceptions that may be propagated when the scene is rendered: </p>

返回

void

---

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. <br /><br /> 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.

返回

void

示例

equirectangularPanorama = equirectangularPanorama && equirectangularPanorama.destroy();

---

isDestroyed()

isDestroyed(): boolean

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

返回

boolean

true if this object was destroyed; otherwise, false.
