Class Ray

constructor

• new Ray(origin?: Vector3D, direction?: Vector3D): Ray

  Creates a new Ray.

  Parameters

  • origin: Vector3D = ...

    The origin point of the ray.

  • direction: Vector3D = ...

    The normalized direction vector of the ray.

  Returns Ray

direction

origin

at

• at(t: number, target?: Vector3D): Vector3D

  Computes the point along the ray at a given distance.

  Parameters

  • t: number

    The distance along the ray.

  • target: Vector3D = ...

    Optional target vector.

  Returns Vector3D

  The computed point.

intersectsBox

• intersectsBox(box: BoundingBox): number

  Tests whether this ray intersects the given AABB. Uses the slab method.

  Parameters

  • box: BoundingBox

    The axis-aligned bounding box.

  Returns number

  The distance t to the intersection, or -1 if no intersection.

intersectsOBB

• intersectsOBB(obb: OBB): number

  Tests whether this ray intersects the given OBB. Uses the slab method projected onto the OBB's local axes.

  Parameters

  • obb: OBB

    The oriented bounding box.

  Returns number

  The distance t to the nearest intersection, or -1 if no intersection.

intersectsSphere

• intersectsSphere(sphere: BoundingSphere): number

  Tests whether this ray intersects the given bounding sphere.

  Parameters

  • sphere: BoundingSphere

    The bounding sphere.

  Returns number

  The distance t to the nearest intersection, or -1 if no intersection.

intersectVolume

• intersectVolume(volume: BoundingVolume): number

  Tests whether this ray intersects any bounding volume (Sphere, Box, OBB).

  Parameters

  • volume: BoundingVolume

    Target bounding volume.

  Returns number

  Distance t to the nearest intersection, or -1 if no intersection.

intersectVolumeDetailed

• intersectVolumeDetailed(
      volume: BoundingVolume,
      outPoint: Vector3D,
      outNormal: Vector3D,
  ): number

  Tests whether this ray intersects any bounding volume, computing the exact world hit point and outward surface normal.

  Parameters

  • volume: BoundingVolume

    Target bounding volume.

  • outPoint: Vector3D

    Vector3D receiving the computed world hit position.

  • outNormal: Vector3D

    Vector3D receiving the outward-pointing surface normal.

  Returns number

  Distance t to the nearest intersection, or -1 if no intersection.

set

• set(origin: Vector3D, direction: Vector3D): this

  Sets the ray's origin and direction.

  Parameters

  • origin: Vector3D

    The new origin.

  • direction: Vector3D

    The new normalized direction.

  Returns this

  This ray instance.
