Struct Plane

#[repr(C)]
pub struct Plane {
    pub normal: Vector3,
    pub d: f32,
}

3D plane in Hessian normal form.

The Hessian form defines all points point which satisfy the equation dot(normal, point) + d == 0, where normal is the normal vector and d the distance from the origin.

Note: almost all methods on Plane require that the normal vector have unit length and will panic if this invariant is violated. This is not separately annotated for each method.

Godot docs

Plane (stable)

Fields

normal: Vector3

Normal vector pointing away from the plane.

d: f32

Distance between the plane and the origin point.

Implementations

impl Plane

pub fn new(unit_normal: Vector3, d: f32) -> Plane

Creates a new Plane from the normal and the distance from the origin d.

Panics

In contrast to construction via Plane { normal, d }, this verifies that normal has unit length, and will panic if this is not the case.

Godot equivalent: Plane(Vector3 normal, float d)

pub fn from_normal_at_origin(normal: Vector3) -> Plane

Create a new Plane through the origin from a normal.

Panics

See Self::new().

Godot equivalent: Plane(Vector3 normal)

pub fn from_point_normal(point: Vector3, normal: Vector3) -> Plane

Create a new Plane from a normal and a point in the plane.

Panics

See Self::new().

Godot equivalent: Plane(Vector3 normal, Vector3 point)

pub fn from_components(nx: f32, ny: f32, nz: f32, d: f32) -> Plane

Creates a new Plane from normal and origin distance.

nx, ny, nz are used for the normal vector. d is the distance from the origin.

Panics

See Self::new().

Godot equivalent: Plane(float a, float b, float c, float d)

pub fn from_points(a: Vector3, b: Vector3, c: Vector3) -> Plane

Creates a new Plane from three points, given in clockwise order.

Panics

Will panic if all three points are colinear.

Godot equivalent: Plane(Vector3 point1, Vector3 point2, Vector3 point3)

pub fn invalid() -> Plane

Creates a new Plane with default values. This new Plane will be invalid.

Godot equivalent: Plane()

pub fn distance_to(self, point: Vector3) -> f32

Finds the shortest distance between the plane and a point.

The distance will be positive if point is above the plane, and will be negative if point is below the plane.

pub fn center(self) -> Vector3

Finds the center point of the plane.

Godot equivalent: Plane.get_center()

pub fn contains_point(self, point: Vector3, tolerance: Option<f32>) -> bool

Finds whether a point is inside the plane or not.

A point is considered part of the plane if its distance to it is less or equal than CMP_EPSILON.

Godot equivalent: Plane.has_point(Vector3 point, float tolerance=1e-05)

pub fn intersect_3(self, b: Plane, c: Plane) -> Option<Vector3>

Finds the intersection point of three planes.

If no intersection point is found, None will be returned.

pub fn intersect_ray(self, from: Vector3, dir: Vector3) -> Option<Vector3>

Finds the intersection point of the plane with a ray.

The ray starts at position from and has direction vector dir, i.e. it is unbounded in one direction.

If no intersection is found (the ray is parallel to the plane or points away from it), None will be returned.

pub fn intersect_segment(self, from: Vector3, to: Vector3) -> Option<Vector3>

Finds the intersection point of the plane with a line segment.

The segment starts at position ‘from’ and ends at position ‘to’, i.e. it is bounded at two directions.

If no intersection is found (the segment is parallel to the plane or does not intersect it), None will be returned.

pub fn is_finite(self) -> bool

Returns true if the plane is finite by calling is_finite on normal and d.

pub fn is_point_over(self, point: Vector3) -> bool

Returns true if point is located above the plane.

pub fn normalized(self) -> Plane

Returns a copy of the plane with its normal and d scaled to the unit length.

A normal length of 0.0 would return a plane with its normal and d being Vector3::ZERO and 0.0 respectively.

pub fn project(self, point: Vector3) -> Vector3

Returns the orthogonal projection of point to the plane.

Trait Implementations

impl ApproxEq for Plane

fn approx_eq(&self, other: &Plane) -> bool

Finds whether the two planes are approximately equal.

Returns if the two Planes are approximately equal, by comparing normal and d separately. If one plane is a negation of the other (both normal and d have opposite signs), they are considered approximately equal.

impl ArrayElement for Plane

fn debug_validate_elements(_array: &Array<Self>) -> Result<(), ConvertError>

impl Clone for Plane

fn clone(&self) -> Plane

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Plane

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for Plane

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats Plane to match Godot’s string representation.

Example

use godot::prelude::*;
let plane = Plane::new(Vector3::new(1.0, 0.0, 0.0), 1.0);
assert_eq!(format!("{}", plane), "[N: (1, 0, 0), D: 1]");

impl Export for Plane

fn export_hint() -> PropertyHintInfo

The export info to use for an exported field of this type, if no other export info is specified.

fn as_node_class() -> Option<ClassName>

If this is a class inheriting Node, returns the ClassName; otherwise None.

impl FromGodot for Plane

fn try_from_godot( via: <Plane as GodotConvert>::Via, ) -> Result<Plane, ConvertError>

Converts the Godot representation to this type, returning Err on failure.

fn from_godot(via: Self::Via) -> Self

⚠️ Converts the Godot representation to this type.

fn try_from_variant(variant: &Variant) -> Result<Self, ConvertError>

Performs the conversion from a Variant, returning Err on failure.

fn from_variant(variant: &Variant) -> Self

⚠️ Performs the conversion from a Variant.

impl GodotConvert for Plane

type Via = Plane

impl Mul<Plane> for Transform3D

type Output = Plane

Performs the * operation.

impl Neg for Plane

fn neg(self) -> <Plane as Neg>::Output

Returns the negative value of the plane by flipping both the normal and the distance value. Meaning it creates a plane that is in the same place, but facing the opposite direction.

type Output = Plane

The resulting type after applying the - operator.

impl PartialEq for Plane

fn eq(&self, other: &Plane) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
