ClippingPlaneCollection

new Cesium.ClippingPlaneCollection(options)
Scene/ClippingPlaneCollection.js 68

Specifies a set of clipping planes. Clipping planes selectively disable rendering in a region on the outside of the specified list of ClippingPlane objects for a single gltf model, 3D Tileset, or the globe.
Name Type Description
options Object optional Object with the following properties:
Name Type Default Description
planes Array.<ClippingPlane> [] optional An array of ClippingPlane objects used to selectively disable rendering on the outside of each plane.
enabled Boolean true optional Determines whether the clipping planes are active.
modelMatrix Matrix4 Matrix4.IDENTITY optional The 4x4 transformation matrix specifying an additional transform relative to the clipping planes original coordinate system.
unionClippingRegions Boolean false optional If true, a region will be clipped if included in any plane in the collection. Otherwise, the region to be clipped must intersect the regions defined by all planes in this collection.
edgeColor Color Color.WHITE optional The color applied to highlight the edge along which an object is clipped.
edgeWidth Number 0.0 optional The width, in pixels, of the highlight applied to the edge along which an object is clipped.

Members

edgeColor : Color
Scene/ClippingPlaneCollection.js 104

The color applied to highlight the edge along which an object is clipped.
Default Value: Color.WHITE

edgeWidth : Number
Scene/ClippingPlaneCollection.js 112

The width, in pixels, of the highlight applied to the edge along which an object is clipped.
Default Value: 0.0

enabled : Boolean
Scene/ClippingPlaneCollection.js 180

If true, clipping will be enabled.
Default Value: true

readonlylength : Number
Scene/ClippingPlaneCollection.js 146

Returns the number of planes in this collection. This is commonly used with ClippingPlaneCollection#get to iterate over all the planes in the collection.

modelMatrix : Matrix4
Scene/ClippingPlaneCollection.js 96

The 4x4 transformation matrix specifying an additional transform relative to the clipping planes original coordinate system.
Default Value: Matrix4.IDENTITY

unionClippingRegions : Boolean
Scene/ClippingPlaneCollection.js 160

If true, a region will be clipped if included in any plane in the collection. Otherwise, the region to be clipped must intersect the regions defined by all planes in this collection.
Default Value: false

Methods

add(plane)
Scene/ClippingPlaneCollection.js 255

Adds the specified ClippingPlane to the collection to be used to selectively disable rendering on the outside of each plane. Use ClippingPlaneCollection#unionClippingRegions to modify how modify the clipping behavior of multiple planes.
Name Type Description
plane ClippingPlane The ClippingPlane to add to the collection.
See:

clone(result) → ClippingPlaneCollection
Scene/ClippingPlaneCollection.js 548

Duplicates this ClippingPlaneCollection instance.
Name Type Description
result ClippingPlaneCollection optional The object onto which to store the result.
Returns:
The modified result parameter or a new ClippingPlaneCollection instance if one was not provided.

contains(clippingPlane) → Boolean
Scene/ClippingPlaneCollection.js 307

Checks whether this collection contains a ClippingPlane equal to the given ClippingPlane.
Name Type Description
clippingPlane ClippingPlane optional The ClippingPlane to check for.
Returns:
true if this collection contains the ClippingPlane, false otherwise.
See:

destroy()
Scene/ClippingPlaneCollection.js 698

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.
Example:
clippingPlanes = clippingPlanes && clippingPlanes .destroy();
See:

get(index) → ClippingPlane
Scene/ClippingPlaneCollection.js 280

Returns the plane in the collection at the specified index. Indices are zero-based and increase as planes are added. Removing a plane shifts all planes after it to the left, changing their indices. This function is commonly used with ClippingPlaneCollection#length to iterate over all the planes in the collection.
Name Type Description
index Number The zero-based index of the plane.
Returns:
The ClippingPlane at the specified index.
See:

isDestroyed() → Boolean
Scene/ClippingPlaneCollection.js 678

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

remove(clippingPlane) → Boolean
Scene/ClippingPlaneCollection.js 321

Removes the first occurrence of the given ClippingPlane from the collection.
Name Type Description
clippingPlane ClippingPlane
Returns:
true if the plane was removed; false if the plane was not found in the collection.
See:

removeAll()
Scene/ClippingPlaneCollection.js 358

Removes all planes from the collection.
See:

update()
Scene/ClippingPlaneCollection.js 434

Called when Viewer or CesiumWidget render the scene to build the resources for clipping planes.

Do not call this function directly.
