OrientedBoundingBox

Represents a bounding box that can be rotated in any direction. Unlike an axis-aligned bounding box, this can rotate with the model. Optimized for performance with object reuse and dirty flag system. Now supports dynamic scaling.

Constructors

OrientedBoundingBox

public void OrientedBoundingBox(Vector3d center, double width, double height, double depth)

Functions

centerDistanceIfIntersects

public synchronized double centerDistanceIfIntersects(BoundingBox aabb, double x, double y, double z)

Returns the center distance when the supplied AABB intersects this exact pose, or -1 when it does not.

distanceFromCenter

public synchronized double distanceFromCenter(double x, double y, double z)

Returns the distance from the current coherent OBB center to a point.

getBaseHalfExtents

public Vector3d getBaseHalfExtents()

getCenter

public Vector3d getCenter()

getCorners

public synchronized Array<Vector3d> getCorners()

Gets the 8 corners of the OBB in world space

getHalfExtents

public Vector3d getHalfExtents()

getRotation

public Matrix3d getRotation()

getScaleModifier

public double getScaleModifier()

intersectsAABB

public synchronized boolean intersectsAABB(BoundingBox aabb)

Exact OBB-vs-AABB intersection via the Separating Axis Theorem (15 axes).

intersectsAABBCoherently

public synchronized boolean intersectsAABBCoherently(BoundingBox aabb)

Runs the cheap enclosing-AABB rejection and the exact SAT test against the same pose.

quickAabbReject

public synchronized boolean quickAabbReject(BoundingBox aabb)

Coarse pre-filter: returns true if the AABB overlaps the OBB's enclosing world-aligned bounding box.

rayIntersection

public synchronized double rayIntersection(Location eyeLocation, double maxDistance)

Checks if a ray from a player's eye location intersects with this OBB.

public synchronized double rayIntersection(double ox, double oy, double oz, double dx, double dy, double dz, double maxDistance)

Ray/segment intersection against this OBB from an explicit origin and direction.

raytraceFromPlayer

public static Optional<ModeledEntity> raytraceFromPlayer(Player player)

Perform a ray trace from a player's eye location in the direction they're looking

raytraceFromPoint

public static Optional<ModeledEntity> raytraceFromPoint(World world, Location location, float maxDistance)

Perform a ray trace from a specific point in a specific direction

setAssociatedEntity

public OrientedBoundingBox setAssociatedEntity(ModeledEntity entity)

Sets the associated entity for scale calculations

update

public synchronized OrientedBoundingBox update(Location location)

Updates both position, rotation, and scale from a Location in one efficient call.

visualizeOBB

public static void visualizeOBB(ModeledEntity entity, int durationTicks, Player player)
