Struct IblComputeFeature 

pub struct IblComputeFeature { /* private fields */ }

IBL (Image-Based Lighting) compute feature.

Performs equirectangular → cube conversion, mipmap generation, and PMREM pre-filtering for specular environment reflections. Due to the multi-phase nature of the work (render passes for blit + mipmap, compute for PMREM), all GPU commands are submitted during Self::extract_and_prepare with a dedicated command encoder.

Produces an ephemeral [IblPassNode] each frame via Self::add_to_graph.

Implementations

impl IblComputeFeature

pub fn new(device: &Device) -> Self

impl IblComputeFeature

pub fn extract_and_prepare(&mut self, ctx: &mut ExtractContext<'_>)

Extract and prepare IBL compute resources.

All IBL compute work is performed here with a dedicated command encoder. The multi-phase nature of the task (equirect → cube, mipmap generation via render passes, PMREM compute dispatches) requires its own submission boundary.

pub fn add_to_graph( &self, ctx: &mut GraphBuilderContext<'_, '_>, source: TextureSource, )

Create an ephemeral [IblPassNode] and add it to the render graph.
