new Cesium.CullingVolume(planes)
Scene/CullingVolume.js 28

The culling volume defined by planes.
Name Type Description
planes Array.<Cartesian4> optional An array of clipping planes.

Members

planes : Array.<Cartesian4>
Scene/CullingVolume.js 36

Each plane is represented by a Cartesian4 object, where the x, y, and z components define the unit vector normal to the plane, and the w component is the distance of the plane from the origin.
Default Value: []

Methods

staticCesium.CullingVolume.fromBoundingSphere(boundingSphere, result) → CullingVolume
Scene/CullingVolume.js 56

Constructs a culling volume from a bounding sphere. Creates six planes that create a box containing the sphere. The planes are aligned to the x, y, and z axes in world coordinates.
Name Type Description
boundingSphere BoundingSphere The bounding sphere used to create the culling volume.
result CullingVolume optional The object onto which to store the result.
Returns:
The culling volume created from the bounding sphere.

computeVisibility(boundingVolume) → Intersect
Scene/CullingVolume.js 117

Determines whether a bounding volume intersects the culling volume.
Name Type Description
boundingVolume Object The bounding volume whose intersection with the culling volume is to be tested.
Returns:
Intersect.OUTSIDE, Intersect.INTERSECTING, or Intersect.INSIDE.
