Class: TransientTexturePool
Defined in: src/gfx/renderJob/graph/transient/TransientTexturePool.ts:69
Physical pool for transient render-graph textures with lifetime-aware aliasing.
Lifecycle:
compile() → LifetimeAnalyzer.analyze() → ResourceLifetime[] → pool.assign(lifetimes) → bindings Map → RenderGraphResourcePool registers () => binding execute() → ctx.getTexture(name) → pool-resolved RenderTexture
Aliasing happens inside one compile window: lifetimes are sorted by firstUseIdx ascending; for each one the pool finds a same-bucket entry whose inUseUntilIdx < firstUseIdx and reuses it, otherwise allocates a fresh RenderTexture. Across compile windows the pool retains every allocated wrapper — the next assign() reshuffles which logical name maps to which physical slot. Dedicated slots (aliasable: false, mip pyramids, etc.) keep their RenderTexture identity stable across windows by binding to a per-name slot that lives outside the bucket reuse pool.
On device-lost the pool calls RenderTexture.destroy() / Texture.delayDestroyTexture() on every slot and clears the buckets; the next compile re-allocates from scratch on the new device.

Constructor
new TransientTexturePool(

Parameters
ctx
Returns
TransientTexturePool
Methods
assign()
assign(
lifetimes):TransientTextureAssignment
Defined in: src/gfx/renderJob/graph/transient/TransientTexturePool.ts:89
Allocate (or reuse) physical wrappers for every transient lifetime. Persistent (imported) lifetimes are ignored — those are registered directly by the builder when the external texture is imported.
Parameters
lifetimes
readonly ResourceLifetime[]
Returns
dispose()
dispose():
void
Defined in: src/gfx/renderJob/graph/transient/TransientTexturePool.ts:225
Destroy every pooled wrapper. Called on graph destroy and device-lost.
Returns
