Type Alias FVec4

pub type FVec4 = FVec<4>;

A 4-vector of f32s.

Aliased Type

pub struct FVec4(/* private fields */);

Implementations

impl FVec4

pub fn w(self) -> f32

The vector’s w component (also called r for the real component of ijk[r]).

pub fn from_raw(raw: C3D_FVec) -> Self

Wrap a raw citro3d_sys::C3D_FVec

pub fn new(x: f32, y: f32, z: f32, w: f32) -> Self

Create a new FVec4 from its components.

Example

let v = FVec4::new(1.0, 2.0, 3.0, 4.0);

pub fn splat(v: f32) -> Self

Create a new FVec4, setting each component to v.

Example

let v = FVec4::splat(1.0);
assert_abs_diff_eq!(v, FVec4::new(1.0, 1.0, 1.0, 1.0));

pub fn perspective_divide(self) -> Self

Divide the vector’s XYZ components by its W component.

Example

let v = FVec4::new(2.0, 4.0, 6.0, 2.0);
assert_abs_diff_eq!(v.perspective_divide(), FVec4::new(1.0, 2.0, 3.0, 1.0));

pub fn dot(self, rhs: Self) -> f32

The dot product of two vectors.

Example

let v1 = FVec4::new(1.0, 2.0, 3.0, 4.0);
let v2 = FVec4::new(1.0, 0.5, 1.0, 0.5);
assert_abs_diff_eq!(v1.dot(v2), 7.0);

pub fn magnitude(self) -> f32

The magnitude of the vector.

Example

let v = FVec4::splat(1.0);
assert_abs_diff_eq!(v.magnitude(), 2.0);

pub fn normalize(self) -> Self

Normalize the vector to a magnitude of 1.0.

Example

let v = FVec4::new(1.0, 2.0, 2.0, 4.0);
assert_abs_diff_eq!(v.normalize(), FVec4::new(0.2, 0.4, 0.4, 0.8));
