[−][src]Struct ultraviolet::vec::Wec2

#[repr(C)]
pub struct Wec2 {
    pub x: f32x4,
    pub y: f32x4,
}

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: f32x4y: 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`[src]

`pub fn map<F>(&self, f: F) -> Self where F: Fn(f32x4) -> f32x4,` [src]

`pub fn apply<F>(&mut self, f: F) where F: Fn(f32x4) -> f32x4,` [src]

`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]

`pub fn zero() -> Self`[src]

`pub fn one() -> Self`[src]

`pub fn xyz(&self) -> Wec3`[src]

`pub fn xyzw(&self) -> Wec4`[src]

`pub fn as_slice(&self) -> &[f32x4]`[src]

`pub fn as_byte_slice(&self) -> &[u8]`[src]

`pub fn as_mut_slice(&mut self) -> &mut [f32x4]`[src]

`pub fn as_mut_byte_slice(&mut self) -> &mut [u8]`[src]

`pub fn as_ptr(&self) -> *const f32x4`[src]

Returns a constant unsafe pointer to the underlying data in the underlying type. This function is safe because all types here are repr(C) and can be represented as their underlying type.

Safety

It is up to the caller to correctly use this pointer and its bounds.

`pub fn as_mut_ptr(&mut self) -> *mut f32x4`[src]

Returns a mutable unsafe pointer to the underlying data in the underlying type. This function is safe because all types here are repr(C) and can be represented as their underlying type.

Safety

It is up to the caller to correctly use this pointer and its bounds.

`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
