Struct Viewport 

pub struct Viewport {
    pub x: f32,
    pub y: f32,
    pub width: f32,
    pub height: f32,
    pub min_depth: f32,
    pub max_depth: f32,
    pub origin: ViewportOrigin,
}

A rectangular viewport region mapping NDC to window coordinates.

Fields

x: f32

X offset in pixels from the window origin.

y: f32

Y offset in pixels from the window origin.

width: f32

Width in pixels.

height: f32

Height in pixels.

min_depth: f32

Near depth range (typically 0.0).

max_depth: f32

Far depth range (typically 1.0).

origin: ViewportOrigin

Coordinate origin convention.

Implementations

impl Viewport

pub fn new(width: f32, height: f32) -> Self

Create a simple full-window viewport with standard depth range.

pub fn with_offset( x: f32, y: f32, width: f32, height: f32, min_depth: f32, max_depth: f32, ) -> Self

Create a viewport with an explicit offset and depth range.

pub fn aspect_ratio(&self) -> f32

Aspect ratio (width / height). Returns f32::INFINITY if height is zero.

pub fn is_portrait(&self) -> bool

Returns true if the viewport is taller than it is wide.

pub fn is_landscape(&self) -> bool

Returns true if the viewport is wider than it is tall.

pub fn has_valid_depth_range(&self) -> bool

Returns true if the depth range is valid (min < max, both in 0..=1).

Trait Implementations

impl Clone for Viewport

fn clone(&self) -> Viewport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Viewport

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

Formats the value using the given formatter.

impl PartialEq for Viewport

fn eq(&self, other: &Viewport) -> 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.
