Struct Mat4 

pub struct Mat4(pub [[f64; 4]; 4]);

A 4x4 matrix stored in row-major order, typically used for affine transforms.

Tuple Fields

0: [[f64; 4]; 4]

Implementations

impl Mat4

pub const fn identity() -> Self

The 4x4 identity matrix.

pub const fn translation(tx: f64, ty: f64, tz: f64) -> Self

Create a translation matrix.

pub const fn scale(sx: f64, sy: f64, sz: f64) -> Self

Create a uniform or non-uniform scale matrix.

pub fn rotation_x(angle: f64) -> Self

Create a rotation matrix around the X axis by angle radians.

pub fn rotation_y(angle: f64) -> Self

Create a rotation matrix around the Y axis by angle radians.

pub fn rotation_z(angle: f64) -> Self

Create a rotation matrix around the Z axis by angle radians.

pub fn mul_point(self, p: Point3) -> Point3

Transform a 3D point by this matrix (assumes w = 1).

pub const fn transpose(self) -> Self

Transpose the matrix.

pub fn determinant(self) -> f64

Compute the determinant using cofactor expansion along the first row.

pub fn inverse(self) -> Result<Self, MathError>

Compute the inverse of the matrix using the adjugate method.

Errors

Returns MathError::SingularMatrix if the determinant is approximately zero.
