lock

• lock(
      boundingBox: BoundingBox,
      matrix?: Mat4,
      extra1?: number,
      extra2?: number,
  ): number

  Registers a BoundingBox for subsequent occlusion testing.

  Parameters

  • boundingBox: BoundingBox

    The bounds of the object in local or world coordinates.

  • Optionalmatrix: Mat4

    Optional transformation matrix (if a local BoundingBox is used).

  • Optionalextra1: number

    Optional extra data 1.

  • Optionalextra2: number

    Optional extra data 2.

  Returns number

  A unique identifier for the registered object.

lockMinMaxScalars

• lockMinMaxScalars(
      data: ArrayLike<number>,
      offset: number,
      matrix?: Mat4,
      extra1?: number,
      extra2?: number,
  ): number

  Registers a BoundingBox for subsequent occlusion testing.

  Parameters

  • data: ArrayLike<number>

    The array containing the bounding box data (min and max points) in local or world coordinates [minX, maxX, minY, maxY, minZ, maxZ].

  • offset: number

    The offset in the array where the bounding box data starts.

  • Optionalmatrix: Mat4

    Optional transformation matrix (if a local BoundingBox is used).

  • Optionalextra1: number

    Optional extra data 1.

  • Optionalextra2: number

    Optional extra data 2.

  Returns number

  A unique identifier for the registered object.

unlock

• unlock(id: number): void

  Releases a previously registered identifier and removes associated data.

  Parameters

  • id: number

    The unique identifier obtained from the lock() call.

  Returns void
