Struct bevy::render::prelude::PerspectiveProjection

pub struct PerspectiveProjection {
    pub fov: f32,
    pub aspect_ratio: f32,
    pub near: f32,
    pub far: f32,
}

A 3D camera projection in which distant objects appear smaller than close objects.

Fields

fov: f32

The vertical field of view (FOV) in radians.

Defaults to a value of π/4 radians or 45 degrees.

aspect_ratio: f32

The aspect ratio (width divided by height) of the viewing frustum.

Bevy’s camera_system automatically updates this value when the aspect ratio of the associated window changes.

Defaults to a value of 1.0.

near: f32

The distance from the camera in world units of the viewing frustum’s near plane.

Objects closer to the camera than this value will not be visible.

Defaults to a value of 0.1.

far: f32

The distance from the camera in world units of the viewing frustum’s far plane.

Objects farther from the camera than this value will not be visible.

Defaults to a value of 1000.0.
