Struct OrthographicProjection

pub struct OrthographicProjection {
    pub z_near: f32,
    pub z_far: f32,
    pub vertical_size: f32,
}

Parallel projection. Object’s size won’t be affected by distance from the viewer, it can be used for 2D games.

Fields

z_near: f32

Location of the near clipping plane. If it is larger than Self::z_far then it will be treated like far clipping plane.

z_far: f32

Location of the far clipping plane. If it is less than Self::z_near then it will be treated like near clipping plane.

vertical_size: f32

Vertical size of the “view box”. Horizontal size is derived value and depends on the aspect ratio of the viewport. Any values very close to zero (from both sides) will be clamped to some minimal value to prevent singularities from occuring.

Implementations

impl OrthographicProjection

pub const Z_NEAR: &'static str = "z_near"

pub const Z_FAR: &'static str = "z_far"

pub const VERTICAL_SIZE: &'static str = "vertical_size"

impl OrthographicProjection

pub fn matrix(&self, frame_size: Vector2<f32>) -> Matrix4<f32>

Returns orthographic projection matrix.

Trait Implementations

impl Clone for OrthographicProjection

fn clone(&self) -> OrthographicProjection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrthographicProjection

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

Formats the value using the given formatter.

impl Default for OrthographicProjection

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OrthographicProjection

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for OrthographicProjection

fn eq(&self, other: &OrthographicProjection) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Reflect for OrthographicProjection

where Self: 'static, f32: Reflect,

fn source_path() -> &'static str

fn type_name(&self) -> &'static str

fn doc(&self) -> &'static str

fn assembly_name(&self) -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly. Alternatively, you can use env!("CARGO_PKG_NAME") as an implementation.

fn type_assembly_name() -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly. Alternatively, you can use env!("CARGO_PKG_NAME") as an implementation.
