public struct Plane
A 2D plane that extends infinitely in a 3D volume.
The contents of the `graphene_plane_t` are private, and should not be modified directly.

Methods:
- public float distance (Point3D point)
Computes the distance of point from a
Plane.
- public bool equal (Plane b)
Checks whether the two given Plane are equal.
- public float get_constant ()
Retrieves the distance along the normal vector of the given
Plane from the origin.
- public Vec3 get_normal ()
Retrieves the normal vector pointing towards the origin of the given
Plane.
- public unowned Plane? init (Vec3? normal, float constant)
Initializes the given Plane using the given
normal vector and constant values.
- public unowned Plane? init_from_plane (Plane src)
Initializes the given Plane using the normal
vector and constant of another Plane.
- public unowned Plane? init_from_point (Vec3 normal, Point3D point)
Initializes the given Plane using the given
normal vector and an arbitrary co-planar point.
- public unowned Plane? init_from_points (Point3D a, Point3D b, Point3D c)
Initializes the given Plane using the 3 provided
co-planar points.
- public unowned Plane? init_from_vec4 (Vec4 src)
Initializes the given Plane using the components
of the given Vec4 vector.
- public Plane negate ()
Negates the normal vector and constant of a Plane
, effectively mirroring the plane across the origin.
- public Plane normalize ()
Normalizes the vector of the given Plane, and
adjusts the constant accordingly.
- public Plane transform (Matrix matrix, Matrix? normal_matrix)
Transforms a Plane
this using the given matrix and normal_matrix.
