Enum BackgroundMapping 

pub enum BackgroundMapping {
    Cube,
    Equirectangular,
    Planar,
}

Texture mapping method for background rendering.

Each variant produces a different shader pipeline variant (via ShaderDefines) to avoid dynamic branching.

Variants

Cube

Standard cubemap sampling.

The view direction is used directly as a cubemap lookup vector. Best for pre-processed environment cubemaps.

Equirectangular

Equirectangular (latitude-longitude) projection.

Maps the view direction to UV coordinates using atan2 / asin. Best for 360° panoramic HDR images.

Planar

Planar screen-space mapping.

The texture is mapped directly to screen space (UV = NDC). Not affected by camera rotation or zoom — acts as a fixed backdrop.

Trait Implementations

impl Clone for BackgroundMapping

fn clone(&self) -> BackgroundMapping

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackgroundMapping

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

Formats the value using the given formatter.

impl Hash for BackgroundMapping

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BackgroundMapping

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