containsBoundBox

  • containsBoundBox(box: BoundBox | Bounds): number

    参数

    返回 number

    The spatial relationship:

    • 1: The bounding box is inside the frustum.
    • 2: The bounding box intersects the frustum.
    • 0: The bounding box is outside and does not intersect the frustum.

    En

    Determines the spatial relationship between this frustum and a bounding box.

    Zh

    确定这个截锥体和包围盒之间的空间关系。

containsBoundSphere

  • containsBoundSphere(sphere: BoundSphere): number

    参数

    返回 number

    The relationship type:

    • 1: The sphere is inside the frustum.
    • 2: The sphere intersects the frustum.
    • 0: The sphere is outside and does not intersect the frustum.

    En

    Determines the spatial relationship between this frustum and a bounding sphere.

    Zh

    确定这个截锥体和包围球之间的空间关系。

containsPoint

  • containsPoint(point: Vector3): number

    参数

    返回 number

    The relationship between the point and the frustum:

    • 1: The point is inside the frustum.
    • 2: The point intersects the frustum.
    • 0: The point is outside and does not intersect the frustum.

    En

    Determines the relationship between the frustum and a point.

    Zh

    确定截锥体与点的关系。

equalsBoundFrustum

equalsObj

  • equalsObj(obj: any): boolean

    参数

    • obj: any

      The object to compare.

    返回 boolean

    En

    Determines whether this object is equal to another object.
