Struct GPUCubemap 

pub struct GPUCubemap { /* private fields */ }

A cubemap uploaded to the GPU, ready to bind (e.g. via BindingInstanceEntry::Cubemap). Opaque — bind it via BindGroupBuilder::texture_cubemap.

empty’s documented use case — rendering into per-face views for environment capture — needs raw per-face wgpu::TextureView access that isn’t available yet: the render-pass recording API itself is still unwrapped (see the crate’s wgpu module-level docs), so there’s currently no way to hand a capture pass a face of this texture to render into. Tracked as a follow-up once pass recording is wrapped.

Implementations

impl GPUCubemap

pub fn write_face(&self, face: u32, pixels: &[u8])

Overwrites one face’s level-0 pixel data (+X, -X, +Y, -Y, +Z, -Z is face 0..=5, matching CubemapDescriptor::from_faces’s order). See GPUTexture::write for the same caveat about mip levels not being regenerated.

pub fn size(&self) -> u32

Edge length in pixels.

Trait Implementations

impl Asset<WGPUBackend> for GPUCubemap

type Source = CubemapDescriptor

The raw source representation stored in Assets.

type Deps<'a> = Res<'a, MipmapGenerator>

Resources (beyond B itself) required to perform the conversion. Use () when there are no extra dependencies.

fn upload<'a>( source: &CubemapDescriptor, backend: &WGPUBackend, mipmap_generator: &Res<'a, MipmapGenerator>, ) -> Option<Self>

Convert source into a processed asset using backend and deps.
