#[repr(C)]pub struct DMat2x4 {
    pub cols: [DVec2x4; 2],
}

Expand description

A 2x2 square matrix.

Useful for performing linear transformations (rotation, scaling) on 2d vectors.

Fields§

§cols: [DVec2x4; 2]

Implementations§

source §

pub fn into_homogeneous(self) -> DMat3x4

Turn this into a homogeneous 2d transformation matrix.

source

pub fn transpose(&mut self)

source

pub fn transposed(&self) -> Self

source

pub fn determinant(&self) -> f64x4

source

pub fn adjugate(&self) -> Self

The adjugate of this matrix, i.e. the transpose of the cofactor matrix.

This is equivalent to the inverse but without dividing by the determinant of the matrix, which can be useful in some contexts for better performance.

One such case is when this matrix is interpreted as a a homogeneous transformation matrix, in which case uniform scaling will not affect the resulting projected 3d version of transformed points or vectors.

source

pub fn inverse(&mut self)

If this matrix is not currently invertable, this function will return an invalid inverse. This status is not checked by the library.

source

pub fn inversed(&self) -> Self

If this matrix is not currently invertable, this function will return an invalid inverse. This status is not checked by the library.

source

pub fn layout() -> Layout

Get the core::alloc::Layout of Self

source

pub fn as_array(&self) -> &[f64x4; 4]

Interpret self as a statically-sized array of its base numeric type

source

pub fn as_mut_array(&mut self) -> &mut [f64x4; 4]

Interpret self as a statically-sized array of its base numeric type

source

pub fn as_component_array(&self) -> &[DVec2x4; 2]

Interpret self as a statically-sized array of its component (column) vector type

source

pub fn as_mut_component_array(&mut self) -> &mut [DVec2x4; 2]

Interpret self as a statically-sized array of its component (column) vector type

source

pub fn as_slice(&self) -> &[f64x4]

Interpret self as a slice of its base numeric type

source

pub fn as_mut_slice(&mut self) -> &mut [f64x4]

Interpret self as a slice of its base numeric type

source

pub fn as_component_slice(&self) -> &[DVec2x4]

Interpret self as a slice of its component (column) vector type

source

pub fn as_mut_component_slice(&mut self) -> &mut [DVec2x4]

Interpret self as a slice of its component (column) vector type

source

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

Interpret self as a slice of bytes

source

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

Interpret self as a slice of bytes

source

pub const fn as_ptr(&self) -> *const f64x4

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.

source

pub fn as_mut_ptr(&mut self) -> *mut f64x4

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.
