Method Descriptions

AABB AABB ( Vector3 position, Vector3 size )

Optional constructor, accepts position and size.

bool encloses ( AABB with )

Returns true if this AABB completely encloses another one.

AABB expand ( Vector3 to_point )

Returns this AABB expanded to include a given point.

float get_area ( )

Gets the area of the AABB.

Vector3 get_endpoint ( int idx )

Gets the position of the 8 endpoints of the AABB in space.

Vector3 get_longest_axis ( )

Returns the normalized longest axis of the AABB.

int get_longest_axis_index ( )

Returns the index of the longest axis of the AABB (according to Vector3::AXIS* enum).

float get_longest_axis_size ( )

Returns the scalar length of the longest axis of the AABB.

Vector3 get_shortest_axis ( )

Returns the normalized shortest axis of the AABB.

int get_shortest_axis_index ( )

Returns the index of the shortest axis of the AABB (according to Vector3::AXIS* enum).

float get_shortest_axis_size ( )

Returns the scalar length of the shortest axis of the AABB.

Vector3 get_support ( Vector3 dir )

Returns the support point in a given direction. This is useful for collision detection algorithms.

AABB grow ( float by )

Returns a copy of the AABB grown a given amount of units towards all the sides.

bool has_no_area ( )

Returns true if the AABB is flat or empty.

bool has_no_surface ( )

Returns true if the AABB is empty.

bool has_point ( Vector3 point )

Returns true if the AABB contains a point.

AABB intersection ( AABB with )

Returns the intersection between two AABB. An empty AABB (size 0,0,0) is returned on failure.

bool intersects ( AABB with )

Returns true if the AABB overlaps with another.

bool intersects_plane ( Plane plane )

Returns true if the AABB is on both sides of a plane.

bool intersects_segment ( Vector3 from, Vector3 to )

Returns true if the AABB intersects the line segment between from and to.

AABB merge ( AABB with )

Returns a larger AABB that contains this AABB and with.
