Struct Mat

pub struct Mat {
    pub x: Vect,
    pub y: Vect,
    pub c: Vect,
}

mat is 3 x 3 matrix used for 2D transformations. Simples explanation i can coe up with: 3x3 matrix is vector trio where x is vector describing x axis and y is describing y axis c is determining where these two axises intersect. Matrix is something like a custom coordinate system. To convert point from classic coordinate system to matrix coordinates you use prj method. Don’t worry though if you do not understand. Matrix in this package is just optional interface you may or may not use. All it does are slightly more complex transformations.

Fields

x: Vect

y: Vect

c: Vect

Implementations

impl Mat

pub const IM: Mat

pub const ZM: Mat

pub fn new(pos: Vect, scl: Vect, rot: f32) -> Mat

pub fn to_glm_mat4(&self) -> Mat4

to_glm_mat4 turns Mat to glm::Mat4 for internal purposes

pub fn moved(self, delta: Vect) -> Mat

returns moved matrix.

pub fn sxy(&mut self, scl: Vect)

scales matrix by vector

pub fn scaled_xy(self, around: Vect, scl: Vect) -> Mat

returns matrix scaled by Vector around Vector

pub fn scaled(self, around: Vect, scl: f32) -> Mat

same as scaled_xy but scaling is homogenous

pub fn rotated(self, around: Vect, ang: f32) -> Mat

returns matrix rotated by angle around a point.

pub fn prj(&self, u: Vect) -> Vect

prj projects point by matrix

pub fn unprj(&self, u: Vect) -> Vect

opposite of prj
