AABB

Axis-Aligned Bounding Box.

Properties

Description

AABB consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.

Property Descriptions

• Vector3 end

Ending corner.

• position

Beginning corner.

Size from position to end.

• AABB AABB ( position, Vector3 size )

Optional constructor, accepts position and size.

• encloses ( AABB with )

Returns if this AABB completely encloses another one.

• expand ( Vector3 to_point )

Returns this AABB expanded to include a given point.

• get_area ( )

• Vector3 get_endpoint ( 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.

• get_longest_axis_index ( )

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

• 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.

• get_shortest_axis_index ( )

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

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

• get_support ( Vector3 dir )

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

• grow ( float by )

• has_no_area ( )

Returns true if the AABB is flat or empty.

• bool has_no_surface ( )

Returns true if the AABB is empty.

• has_point ( Vector3 point )

Returns true if the AABB contains a point.

• intersection ( AABB with )

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

• intersects ( AABB with )

Returns true if the AABB overlaps with another.

• intersects_plane ( Plane plane )

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

• intersects_segment ( Vector3 from, to )

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

• AABB merge ( with )

Returns a larger AABB that contains this AABB and .
