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

Formats the value using the given formatter.

impl Default for ProjectionMatrix

fn default() -> Self

Returns the “default value” for a type.

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

fn from(data: [[f64; 4]; 4]) -> Self

Converts to this type from the input type.

impl Mul<(f64, f64, f64)> for ProjectionMatrix

type Output = (i32, i32)

The resulting type after applying the * operator.

fn mul(self, (x, y, z): (f64, f64, f64)) -> (i32, i32)

Performs the * operation.

impl Mul<(i32, i32, i32)> for ProjectionMatrix

type Output = (i32, i32)

The resulting type after applying the * operator.

fn mul(self, (x, y, z): (i32, i32, i32)) -> (i32, i32)

Performs the * operation.

impl Mul for ProjectionMatrix

type Output = ProjectionMatrix

The resulting type after applying the * operator.

fn mul(self, other: ProjectionMatrix) -> ProjectionMatrix

Performs the * operation.

impl Copy for ProjectionMatrix

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
