方法

static Cesium.CullingVolume.fromBoundingSphere(boundingSphere, result)CullingVolume

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.
参数名称 类型 描述信息
boundingSphere BoundingSphere The bounding sphere used to create the culling volume.
result CullingVolume 可选 The object onto which to store the result.
返回值:
The culling volume created from the bounding sphere.

computeVisibility(boundingVolume)Intersect

Determines whether a bounding volume intersects the culling volume.
参数名称 类型 描述信息
boundingVolume object The bounding volume whose intersection with the culling volume is to be tested.
返回值:
Intersect.OUTSIDE, Intersect.INTERSECTING, or Intersect.INSIDE.
