Class BoundingSphere

constructor

• new BoundingSphere(
      min: DeepImmutable<Vector3>,
      max: DeepImmutable<Vector3>,
      worldMatrix?: DeepImmutableObject<Matrix>,
  ): BoundingSphere

  Creates a new bounding sphere

  Parameters

  • min: DeepImmutable<Vector3>

    defines the minimum vector (in local space)

  • max: DeepImmutable<Vector3>

    defines the maximum vector (in local space)

  • OptionalworldMatrix: DeepImmutableObject<Matrix>

    defines the new world matrix

  Returns BoundingSphere

getWorldMatrix

• getWorldMatrix(): DeepImmutable<Matrix>

  Gets the world matrix of the bounding box

  Returns DeepImmutable<Matrix>

  a matrix

intersectsPoint

• intersectsPoint(point: DeepImmutable<Vector3>): boolean

  Tests if a point is inside the bounding sphere

  Parameters

  • point: DeepImmutable<Vector3>

    defines the point to test

  Returns boolean

  true if the point is inside the bounding sphere

isCenterInFrustum

• isCenterInFrustum(frustumPlanes: DeepImmutableObject<Plane>[]): boolean

  Tests if the bounding sphere center is in between the frustum planes. Used for optimistic fast inclusion.

  Parameters

  • frustumPlanes: DeepImmutableObject<Plane>[]

    defines the frustum planes to test

  Returns boolean

  true if the sphere center is in between the frustum planes

isInFrustum

• isInFrustum(frustumPlanes: DeepImmutableObject<Plane>[]): boolean

  Tests if the bounding sphere is intersecting the frustum planes

  Parameters

  • frustumPlanes: DeepImmutableObject<Plane>[]

    defines the frustum planes to test

  Returns boolean

  true if there is an intersection

reConstruct

• reConstruct(
      min: DeepImmutable<Vector3>,
      max: DeepImmutable<Vector3>,
      worldMatrix?: DeepImmutableObject<Matrix>,
  ): void

  Recreates the entire bounding sphere from scratch as if we call the constructor in place

  Parameters

  • min: DeepImmutable<Vector3>

    defines the new minimum vector (in local space)

  • max: DeepImmutable<Vector3>

    defines the new maximum vector (in local space)

  • OptionalworldMatrix: DeepImmutableObject<Matrix>

    defines the new world matrix

  Returns void

scale

• scale(factor: number): BoundingSphere

  Scale the current bounding sphere by applying a scale factor

  Parameters

  • factor: number

    defines the scale factor to apply

  Returns BoundingSphere

  the current bounding box

StaticCreateFromCenterAndRadius

• CreateFromCenterAndRadius(
      center: DeepImmutable<Vector3>,
      radius: number,
      matrix?: DeepImmutableObject<Matrix>,
  ): BoundingSphere

  Creates a sphere from a center and a radius

  Parameters

  • center: DeepImmutable<Vector3>

  • radius: number

    radius

  • Optionalmatrix: DeepImmutableObject<Matrix>

    Optional worldMatrix

  Returns BoundingSphere

  The sphere

StaticIntersects

• Intersects(
      sphere0: DeepImmutable<BoundingSphere>,
      sphere1: DeepImmutable<BoundingSphere>,
  ): boolean

  Checks if two sphere intersect

  Parameters

  • sphere0: DeepImmutable<BoundingSphere>

    sphere 0

  • sphere1: DeepImmutable<BoundingSphere>

    sphere 1

  Returns boolean

  true if the spheres intersect
