A 4x4 column major matrix.
This type is 16 byte aligned.
Methods
impl Mat4
[src]
pub fn zero() -> Self
[src]
Creates a new Mat4
with all elements set to 0.0
.
pub fn identity() -> Self
[src]
Creates a new Mat4
identity matrix.
pub fn new(x_axis: Vec4, y_axis: Vec4, z_axis: Vec4, w_axis: Vec4) -> Self
[src]
please use Mat4::from_cols
instead
pub fn from_cols(x_axis: Vec4, y_axis: Vec4, z_axis: Vec4, w_axis: Vec4) -> Self
[src]
Creates a new Mat4
from four column vectors.
pub fn from_cols_array(m: &[f32; 16]) -> Self
[src]
Creates a new Mat4
from a [f32; 16]
stored in column major order.
If your data is stored in row major you will need to transpose
the resulting Mat4
.
pub fn to_cols_array(&self) -> [f32; 16]
[src]
Creates a new [f32; 16]
storing data in column major order.
If you require data in row major order transpose
the Mat4
first.
pub fn from_cols_array_2d(m: &[[f32; 4]; 4]) -> Self
[src]
Creates a new Mat4
from a [[f32; 4]; 4]
stored in column major order.
If your data is in row major order you will need to transpose
the resulting Mat4
.
pub fn to_cols_array_2d(&self) -> [[f32; 4]; 4]
[src]
Creates a new [[f32; 4]; 4]
storing data in column major order.
If you require data in row major order transpose
the Mat4
first.

[src]
pub fn look_at_lh(eye: Vec3, center: Vec3, up: Vec3) -> Self
[src]
pub fn look_at_rh(eye: Vec3, center: Vec3, up: Vec3) -> Self
[src]
pub fn perspective_glu_rh(
fov_y_radians: f32,
aspect_ratio: f32,
z_near: f32,
z_far: f32
) -> Mat4
[src]
fov_y_radians: f32,
aspect_ratio: f32,
z_near: f32,
z_far: f32
) -> Mat4
Builds a right-handed perspective projection matrix with [-1,1] depth range.
This is the equivalent of the common perspective function gluPerspective
in OpenGL.
See https://www.khronos.org/opengl/wiki/GluPerspective_code
pub fn perspective_infinite_rh(
fov_y_radians: f32,
aspect_ratio: f32,
z_near: f32
) -> Mat4
[src]
fov_y_radians: f32,
aspect_ratio: f32,
z_near: f32
) -> Mat4
Build infinite right-handed perspective projection matrix with [0,1] depth range.
pub fn perspective_infinite_reverse_rh(
fov_y_radians: f32,
aspect_ratio: f32,
z_near: f32
) -> Mat4
[src]
fov_y_radians: f32,
aspect_ratio: f32,
z_near: f32
) -> Mat4
Build infinite reverse right-handed perspective projection matrix with [0,1] depth range.
pub fn mul_vec4(&self, other: Vec4) -> Vec4
[src]
pub fn mul_mat4(&self, other: &Self) -> Self
[src]
Multiplies two 4x4 matrices.
pub fn add_mat4(&self, other: &Self) -> Self
[src]
pub fn sub_mat4(&self, other: &Self) -> Self
[src]
pub fn mul_scalar(&self, other: f32) -> Self
[src]
pub fn transform_point3(&self, other: Vec3) -> Vec3
[src]
pub fn transform_vector3(&self, other: Vec3) -> Vec3
[src]
pub fn abs_diff_eq(&self, other: Self, max_abs_diff: f32) -> bool
[src]
Returns true if the absolute difference of all elements between self
and other
is less than or equal to max_abs_diff
.
This can be used to compare if two Mat4
's contain similar elements. It
works best when comparing with a known value. The max_abs_diff
that
should be used used depends on the values being compared against.
