Struct IblBaker 

pub struct IblBaker { /* private fields */ }

One-time IBL bake service. Registered as a shared resource at bootstrap and driven by the ibl_bake DataSystem, which calls ensure_baked every frame; the bake itself runs only on the first call.

Implementations

impl IblBaker

pub fn new() -> Self

Creates an unbaked baker. The bake happens lazily on the first ensure_baked once a device is available.

pub fn is_baked(&self) -> bool

Whether the one-time bake has already run.

pub fn wait_for_environment(&self) -> bool

Records one tick spent waiting for the scene’s environment asset to load. Returns true while the caller should keep waiting, and false once the budget is spent and it must bake the procedural sky instead.

pub fn ensure_baked( &self, device: &dyn GraphicsDevice, pipeline_system: &dyn PipelineSystem, sun_direction: Vec3, env_source: Option<&CpuTexture>, )

Bakes the IBL resources on the first call; a no-op afterwards. Idempotent and safe to call every frame.

sun_direction points toward the sun in world space — the scene’s directional light, so the procedural sky’s sun disk agrees with the light that casts the shadows. A zero/degenerate vector falls back to [DEFAULT_SUN_DIRECTION]. The bake is one-time, so this captures the light as it stands on the first tick.

env_source is an authored equirectangular environment map (see EnvironmentMap); None bakes the procedural sky instead. Both fill the same env cube, so the rest of the chain is unaffected.

pub fn bindings(&self) -> Option<IblGpuBindings>

Returns the group-3 IBL bindings once baked, else None (lit lanes skip the IBL term until it is ready).

impl Default for IblBaker

fn default() -> IblBaker
