Class BoundingSphere

constructor

• new BoundingSphere(center?: Vec3, radius?: number): BoundingSphere

• Creates a new BoundingSphere instance.

  Parameters

  • Optionalcenter: Vec3 = ...

    The world space coordinate marking the center of the sphere. The constructor takes a reference of this parameter.
  • Optionalradius: number = 0.5

    The radius of the bounding sphere. Defaults to 0.5.

  Returns BoundingSphere

  Example

  // Create a new bounding sphere centered on the origin with a radius of 0.5
  const sphere = new pc.BoundingSphere();
  Copy

center

radius

intersectsBoundingSphere

• intersectsBoundingSphere(sphere: BoundingSphere): boolean

• Test if a Bounding Sphere is overlapping, enveloping, or inside this Bounding Sphere.

  Parameters

  • sphere: BoundingSphere

    Bounding Sphere to test.

  Returns boolean

  True if the Bounding Sphere is overlapping, enveloping, or inside this Bounding Sphere and false otherwise.

intersectsRay

• intersectsRay(ray: Ray, point?: Vec3): boolean

• Test if a ray intersects with the sphere.

  Parameters

  • ray: Ray

    Ray to test against (direction must be normalized).
  • Optionalpoint: Vec3

    If there is an intersection, the intersection point will be copied into here.

  Returns boolean

  True if there is an intersection.
