Struct godot::prelude::Vector3

#[repr(C)]
pub struct Vector3 {
    pub x: f32,
    pub y: f32,
    pub z: f32,
}

Vector used for 3D math using floating point coordinates.

3-element structure that can be used to represent positions in 3D space or any other triple of numeric values.

It uses floating-point coordinates of 32-bit precision, unlike the engine’s float type which is always 64-bit. The engine can be compiled with the option precision=double to use 64-bit vectors; use the gdext library with the double-precision feature in that case.

See Vector3i for its integer counterpart.

Fields

x: f32

The vector’s X component.

y: f32

The vector’s Y component.

z: f32

The vector’s Z component.

pub fn cross(self, with: Vector3) -> Vector3

Returns the cross product of this vector and with.

This returns a vector perpendicular to both this and with, which would be the normal vector of the plane defined by the two vectors. As there are two such vectors, in opposite directions, this method returns the vector defined by a right-handed coordinate system. If the two vectors are parallel this returns an empty vector, making it useful for testing if two vectors are parallel.

pub fn octahedron_decode(uv: Vector2) -> Vector3

Returns the Vector3 from an octahedral-compressed form created using Vector3::octahedron_encode (stored as a Vector2).

pub fn octahedron_encode(self) -> Vector2

Returns the octahedral-encoded (oct32) form of this Vector3 as a Vector2.

Since a Vector2 occupies 1/3 less memory compared to Vector3, this form of compression can be used to pass greater amounts of Vector3::normalized Vector3s without increasing storage or memory requirements. See also Vector3::octahedron_decode.

Note: Octahedral compression is lossy, although visual differences are rarely perceptible in real world scenarios.

Panics

If vector is not normalized.

pub fn outer(self, with: Vector3) -> Basis

Returns the outer product with with.

pub fn rotated(self, axis: Vector3, angle: f32) -> Vector3

Returns this vector rotated around axis by angle radians. axis must be normalized.

Panics

pub fn signed_angle_to(self, to: Vector3, axis: Vector3) -> f32

Returns the signed angle to the given vector, in radians. The sign of the angle is positive in a counter-clockwise direction and negative in a clockwise direction when viewed from the side specified by the axis.

pub fn slerp(self, to: Vector3, weight: f32) -> Vector3

Returns the spherical linear interpolation between the vector and to by the weight amount.

The variable weight is representing the amount of interpolation, which is on the range of 0.0 to 1.0.

Length is also interpolated in the case that the input vectors have different lengths. If both input vectors have zero length or are collinear to each other, the method instead behaves like Vector3::lerp.
