Implementations

impl LocalTransform

pub fn identity() -> LocalTransform

Methods from Deref<Target = Mat4>

pub fn to_cols_array(&self) -> [f32; 16]

Creates a [f32; 16] storing data in column major order. If you require data in row major order transpose the matrix first.

pub fn to_cols_array_2d(&self) -> [[f32; 4]; 4]

Creates a [[f32; 4]; 4] storing data in column major order. If you require data in row major order transpose the matrix first.

pub fn to_scale_rotation_translation(&self) -> (Vec3, Quat, Vec3)

Extracts scale, rotation and translation from self. The input matrix is expected to be a 4x4 homogeneous transformation matrix otherwise the output will be invalid.

pub fn set_x_axis(&mut self, x: Vec4)

pub fn set_y_axis(&mut self, y: Vec4)

pub fn set_z_axis(&mut self, z: Vec4)

pub fn set_w_axis(&mut self, w: Vec4)

pub fn x_axis(&self) -> Vec4

pub fn y_axis(&self) -> Vec4

pub fn z_axis(&self) -> Vec4

pub fn w_axis(&self) -> Vec4

pub fn transpose(&self) -> Mat4

Returns the transpose of self.

pub fn determinant(&self) -> f32

Returns the determinant of self.

pub fn inverse(&self) -> Mat4

Returns the inverse of self.

If the matrix is not invertible the returned matrix will be invalid.

pub fn mul_vec4(&self, other: Vec4) -> Vec4

pub fn mul_mat4(&self, other: &Mat4) -> Mat4

Multiplies two 4x4 matrices.

pub fn add_mat4(&self, other: &Mat4) -> Mat4

pub fn sub_mat4(&self, other: &Mat4) -> Mat4

pub fn mul_scalar(&self, other: f32) -> Mat4

pub fn transform_point3(&self, other: Vec3) -> Vec3

Transforms the given Vec3 as 3D point. This is the equivalent of multiplying the Vec3 as a Vec4 where w is 1.0.

pub fn transform_vector3(&self, other: Vec3) -> Vec3

Transforms the give Vec3 as 3D vector. This is the equivalent of multiplying the Vec3 as a Vec4 where w is 0.0.

pub fn abs_diff_eq(&self, other: Mat4, max_abs_diff: f32) -> bool

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.
