Implementations

impl Mat4

pub fn new() -> Self

Build a new (identity) Mat4, which applies no transformations.

pub fn ptr(&self) -> *const f32

Returns a pointer to the matrix, readable by OpenGL.

pub fn add(&mut self, mat: Mat4)

Adds mat to self

pub fn mult(&mut self, mat: Mat4)

Multiplies this Mat4 (self) with another one (mat), further from the initial vertex position vector, so the resulting transformation will be the chaining of both matrices’ transformations: first self, then mat.

pub fn div(&mut self, scalar: f32)

Divides self by a float, scalar.

pub fn interpolate(&mut self, mat: Mat4, advancement: f32)

Interpolates self with mat given the advancement (0.0 to 1.0)

pub fn scale(x_scale: f32, y_scale: f32, z_scale: f32) -> Self

Add a scale transformation to the Mat4, for each axis. The scale center is (0.0, 0.0, 0.0).

pub fn rotate_x(angle: f32) -> Self

Add a rotation transformation to the Mat4 around the X axis, clockiwse. The rotation center is (0.0, 0.0, 0.0).

pub fn rotate_y(angle: f32) -> Self

Add a rotation transformation to the Mat4 around the Y axis, clockiwse. The rotation center is (0.0, 0.0, 0.0).

pub fn rotate_z(angle: f32) -> Self

Add a rotation transformation to the Mat4 around the Z axis, clockiwse. The rotation center is (0.0, 0.0, 0.0).

pub fn translate(x_move: f32, y_move: f32, z_move: f32) -> Self

Add a translation transformation to the Mat4.

pub fn lookat( eye_x: f32, eye_y: f32, eye_z: f32, target_x: f32, target_y: f32, target_z: f32, up_x: f32, up_y: f32, up_z: f32, ) -> Self

For view matrix. Moves the “camera” to (eye_x, eye_y, eye_z), looking at (target_x, target_y, target_z), with athe (up_x, up_y, up_z) up vector.

pub fn project_orthographic( l: f32, r: f32, b: f32, t: f32, n: f32, f: f32, ) -> Self

For projection matrix. Defines an orthographic projection matrix with the given [left-right] - [top-bottom] - [near-far] frustrum. The default Frustrum is set to left-right: [-1.0, 1.0], top-bottom: [-1.0, 1.0], near-far: [-1.0, 1.0]

pub fn project_perspective( l: f32, r: f32, b: f32, t: f32, n: f32, f: f32, ) -> Self

For projection matrix. Defines an perspective projection matrix with the given [left-right] - [top-bottom] - [near-far] frustrum. The default Frustrum is set to left-right: [-1.0, 1.0], top-bottom: [-1.0, 1.0], near-far: [-1.0, 1.0]
