Struct ProjectionMatrix

pub struct ProjectionMatrix(/* private fields */);

The projection matrix which is used to project the 3D space to the 2D display panel

Implementations

impl ProjectionMatrix

pub fn one() -> Self

Returns the identity matrix

pub fn zero() -> Self

Returns the zero maxtrix

pub fn shift(x: f64, y: f64, z: f64) -> Self

Returns the matrix which shift the coordinate

pub fn rotate(x: f64, y: f64, z: f64) -> Self

Returns the matrix which rotates the coordinate

pub fn scale(factor: f64) -> Self

Returns the matrix that applies a scale factor

pub fn normalize(&mut self)

Normalize the matrix, this will make the metric unit to 1

pub fn projected_depth(&self, (x, y, z): (i32, i32, i32)) -> i32

Get the distance of the point in guest coordinate from the screen in pixels

Trait Implementations

impl AsMut<[[f64; 4]; 4]> for ProjectionMatrix

fn as_mut(&mut self) -> &mut [[f64; 4]; 4]

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<[[f64; 4]; 4]> for ProjectionMatrix

fn as_ref(&self) -> &[[f64; 4]; 4]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ProjectionMatrix

fn clone(&self) -> ProjectionMatrix

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProjectionMatrix

fn fmt(&self, f: &mut Formatter<'_>) -> Result
