[−][src]Struct ultraviolet::vec::Wec2
A set of two coordinates which may be interpreted as a vector or point in 2d space.
Generally this distinction between a point and vector is more of a pain than it is worth to distinguish on a type level, however when converting to and from homogeneous coordinates it is quite important.
Fields
x: f32x4
y: f32x4
Methods
impl Wec2
[src]
pub fn new(x: f32x4, y: f32x4) -> Self
[src]
pub fn broadcast(val: f32x4) -> Self
[src]
pub fn unit_x() -> Self
[src]
pub fn unit_y() -> Self
[src]
pub fn into_homogeneous_point(self) -> Wec3
[src]
Create a homogeneous 2d point from this vector interpreted as a point, meaning the homogeneous component will start with a value of 1.0.
pub fn into_homogeneous_vector(self) -> Wec3
[src]
Create a homogeneous 2d vector from this vector, meaning the homogeneous component will always have a value of 0.0.
pub fn from_homogeneous_point(v: Wec3) -> Self
[src]
Create a 2d point from a homogeneous 2d point, performing division by the homogeneous component. This should not be used for homogeneous 2d vectors, which will have 0 as their homogeneous component.
pub fn from_homogeneous_vector(v: Wec3) -> Self
[src]
Create a 2d vector from homogeneous 2d vector, which simply discards the homogeneous component.
pub fn dot(&self, other: Wec2) -> f32x4
[src]
pub fn wedge(&self, other: Wec2) -> WBivec2
[src]
The wedge (aka exterior) product of two vectors.
This operation results in a bivector, which represents
the plane parallel to the two vectors, and which has a
'oriented area' equal to the parallelogram created by extending
the two vectors, oriented such that the positive direction is the
one which would move self
closer to other
.
pub fn geom(&self, other: Wec2) -> WRotor2
[src]
The geometric product of this and another vector, which is defined as the sum of the dot product and the wedge product.
This operation results in a 'rotor', named as such as it may define
a rotation. The rotor which results from the geometric product
will rotate in the plane parallel to the two vectors, by twice the angle between
them and in the opposite direction (i.e. it will rotate in the direction that would
bring other
towards self
, and rotate in that direction by twice the angle between them).
pub fn rotate_by(&mut self, rotor: WRotor2)
[src]
pub fn rotated_by(self, rotor: WRotor2) -> Self
[src]
pub fn reflected(&self, normal: Wec2) -> Self
[src]
pub fn mag_sq(&self) -> f32x4
[src]
pub fn mag(&self) -> f32x4
[src]
pub fn normalize(&mut self)
[src]
pub fn normalized(&self) -> Self
[src]
pub fn mul_add(&self, mul: Wec2, add: Wec2) -> Self
[src]
pub fn abs(&self) -> Self
[src]
pub fn clamp(&mut self, min: Self, max: Self)
[src]
pub fn clamped(self, min: Self, max: Self) -> Self

F: Fn(f32x4) -> f32x4,
[src]
F: Fn(f32x4) -> f32x4,
pub fn apply<F>(&mut self, f: F) where
F: Fn(f32x4) -> f32x4,
[src]
F: Fn(f32x4) -> f32x4,
pub fn max_by_component(self, other: Self) -> Self
[src]
pub fn min_by_component(self, other: Self) -> Self
[src]
pub fn component_max(&self) -> f32x4
[src]
pub fn component_min(&self) -> f32x4
[src]

impl Wec2
[src]
pub fn new_splat(x: f32, y: f32) -> Self
[src]
pub fn splat(vec: Vec2) -> Self
[src]
pub fn merge(mask: f32x4, tru: Self, fals: Self) -> Self
[src]
Merge two vectors together lanewise using mask
as a mask.
This is essentially a bitwise merge operation, such that any point where
there is a 1 bit in mask
, the output will put the bit from tru
, while
where there is a 0 bit in mask
, the output will put the bit from fals
