Struct polystrip::vertex::Matrix4

#[repr(transparent)]pub struct Matrix4(pub ColumnMatrix4<f32>);

A 4 x 4 column major matrix in screen space

Implementations

impl Matrix4

pub fn identity() -> Matrix4

Returns the identity matrix.

pub fn translate(v: Vector2) -> Matrix4

Returns a matrix that translates by the given X and Y values, in screen space

pub fn rotate(r: f32) -> Matrix4

Returns a matrix that rotates the XY plane counterclockwise about the origin by the given angle.

Interprets the angle to be in radians.

pub fn scale(f: f32) -> Matrix4

Returns a matrix that scales the XY plane by the given factor

pub fn scale_nonuniform(x: f32, y: f32) -> Matrix4

Returns a matrix that scales the X coordinate by the given factor and the Y coordinate by the given factor.

pub fn perspective(fovy: f32, aspect: f32, near: f32, far: f32) -> Matrix4

Returns a simple perspective matrix from the four passed parameters. Equivalent to the gluPerspective function in OpenGL.

Parameters

• fovy: The angle of the field of view up and down, in radians. Must be nonzero and cannot be a multiple of tau (2π)
• aspect: The ratio of screen width to screen height. Should be updated when the window is resized. Must be nonzero.
• near: Distance from the camera to the near clipping plane, in screen-space coordinates.
• far: Distance from the camera to the far clipping plane, in screen-space coordinates. Must not be equal to near.
