Struct OrientedBoundingBox3 

pub struct OrientedBoundingBox3 {
    pub center: Point3,
    pub orientation: UnitQuat,
    /* private fields */
}

An oriented bounding box.

Fields

center: Point3

The center of the OBB.

orientation: UnitQuat

The rotation of the OBB.

Implementations

impl OrientedBoundingBox3

pub fn new(center: Point3, orientation: UnitQuat, extents: Vec3) -> Self

Create a new OBB from the given center, orientation, and extents.

pub fn extents(&self) -> Vec3

Extents of the OBB along the x, y, and z axes. Always half of size.

pub fn size(&self) -> Vec3

Returns the size of the OBB.

pub fn x_axis(&self) -> UnitVec3

Returns the x-axis of the OBB in world space.

pub fn y_axis(&self) -> UnitVec3

Returns the y-axis of the OBB in world space.

pub fn z_axis(&self) -> UnitVec3

Returns the z-axis of the OBB in world space.

pub fn translate(&mut self, translation: Vec3)

Move the OBB by the given translation

pub fn axis_aligned_bounding_box(&self) -> Aabb3

Calculate the axis aligned bounding box of the OBB

pub fn vertices(&self) -> [Point3; 8]

Calculate the 8 vertices of the OBB in world space.

Note

The order of the vertices is:

 
  3-------7
 /|      /|
2-------6 |
| |     | |
| 1-----|-5
|/      |/
0-------4
y   z
| /
 -- x

pub fn overlaps(&self, other: &Self) -> bool

Overlap test for two OBB by using the separating axis theorem.
