Class: SortedTransparentPass
Defined in: src/gfx/renderJob/graph/passes/SortedTransparentPass.ts:39
Mutator pass that renders sorted transparent geometry AFTER opaque rendering + SceneColorPyramid + Transmission. Reopens the main color attachment with loadOp='load' so opaque + transmission contents are preserved, then draws the transparent list and any Graphic3D overlays.
When the engine is configured with render.useOIT = true and materials carry oitMode === 'weighted', the OIT pass at the same stage owns the weighted half of the pipeline; this pass renders the subset of materials still on the sorted path.
Resource flow:
- read
_SceneColorPyramid— chains after pyramid copy. - read
_TransparentDrawContext— chains after ColorPass (creator). - mutator write on
_ColorBuffer— declares the in-place write.

Properties
materialPasses
readonlymaterialPasses: readonlyPassType[] =[]
Defined in: src/gfx/renderJob/graph/RenderGraphPass.ts:324
Material-side pass types consumed. Optional; defaults to none for pure compute / copy passes.
Inherited from
RenderGraphPass.materialPasses
enabled
enabled:
boolean=true
Defined in: src/gfx/renderJob/graph/RenderGraphPass.ts:332
Runtime kill switch. graph.disablePass(name) flips this. A disabled pass is treated as if it weren't in the graph: it's filtered out before validation + topo sort, and skipped during execute. Disabling a producer whose output is read by another enabled pass makes the next compile() throw UnresolvedResourceError.
Inherited from
layerMask
layerMask:
number=VisibleLayer.All
Defined in: src/gfx/renderJob/graph/RenderGraphPass.ts:347
Which scene layers this pass consumes, as a bitmask. Default VisibleLayer.All reproduces the legacy "draw every collected node" behaviour. Custom passes (or custom RendererJobs wiring built-in passes) override this to restrict the pass to specific composition layers — combined with the active camera's cullingMask at execute time via bitwise AND, then matched against each node's visibleLayer:
(node.visibleLayer & pass.layerMask & camera.cullingMask) !== 0
Use collectLayered from inside execute() to fetch the filtered opaque/transparent lists; it threads layerMask and the camera mask through EntityCollect.getLayerLists.
Inherited from
reads
readonlyreads: readonlystring[]
Defined in: src/gfx/renderJob/graph/RenderGraphPass.ts:353
Names this pass reads. Populated on the first RenderGraph.compile() that processes this pass, from the b.read(...) calls inside its setup(). Empty frozen array before compile.
Inherited from
writes
readonlywrites: readonlystring[]
Defined in: src/gfx/renderJob/graph/RenderGraphPass.ts:358
Names this pass writes (creator + mutator combined). Populated on the first RenderGraph.compile() from the b.write(...) calls inside setup(). Empty frozen array before compile.
Inherited from
creates
readonlycreates: readonlystring[]
Defined in: src/gfx/renderJob/graph/RenderGraphPass.ts:363
Subset of writes for which this pass was the creator (called b.write(name, factory), not b.write(name)). The validator's single-creator rule operates on this set.
Inherited from
dependencies?
optionaldependencies?:ReadonlySet<string>
Defined in: src/gfx/renderJob/graph/RenderGraphPass.ts:377
Explicit ordering dependencies on other pass names, set either from setup() via b.dependsOn(name) or by direct assignment before the next compile. Each entry adds a topo-sort edge <name> → this, independent of any resource edge. Use for side-effect dependencies the graph can't see (indirect buffers, off-screen RTs consumed via materials, etc.).
Beyond the edge, an entry here also positions this pass in the compiled schedule: the effective scheduling key collapses to "just after the latest dep", so a late-added pass with explicit dependencies runs next to its dep instead of trailing at the end of the queue. See topoSort for the full rule.
Inherited from
name
readonlyname:"SortedTransparentPass"='SortedTransparentPass'
Defined in: src/gfx/renderJob/graph/passes/SortedTransparentPass.ts:40
Unique pass identifier. Used as the graph-node key and in error messages — prefer PascalCase ending in Pass (e.g. ShadowPass, ColorPass).

Methods
dispatchEvent()
dispatchEvent(
event):void
Defined in: src/event/CEventDispatcher.ts:24
Dispatch an event to all registered objects with a specific type of listener.
Parameters
event
Returns
void
Inherited from
addEventListener()
addEventListener(
type,callback,thisObject,param?,priority?):number
Defined in: src/event/CEventDispatcher.ts:78
register an event listener to event distancher.
Parameters
type
string | number
{string} event type.
callback
Function
{Function} The callback function that handles events. This function must accept an Event3D object as its unique parameter and cannot return any result. for example: function(evt:Event3D):void.
thisObject
any
{any} Current registration object, it'll call callback function.
param?
any = null
{any} the data binded to registered event, the default value is null.
priority?
number = 0
{number} The priority of callback function execution, with a larger set value having priority to call
Returns
number
Returns register event id

RenderGraphPass.addEventListener
removeEventListener()
removeEventListener(

Defined in: src/event/CEventDispatcher.ts:112
Remove Event Listening
Parameters
type
string | number
{string} event type
callback
Function
{Function} callback function of event register
thisObject
any
{any} The current registered object.
Returns
void
Inherited from
RenderGraphPass.removeEventListener
removeEventListenerAt()
removeEventListenerAt(
id):boolean
Defined in: src/event/CEventDispatcher.ts:132
Remove an event Listening with id
Parameters
id

removeAllEventListener()
removeAllEventListener(
eventType?):void
Defined in: src/event/CEventDispatcher.ts:152
Specify a event type to remove all related event listeners eventType event type, set null to remove all event listeners
Parameters
eventType?

Returns
void

containEventListener()
containEventListener(
type):boolean
Defined in: src/event/CEventDispatcher.ts:184
whether the target presence of a listener with event type.
Parameters
type
string
{string} event type.
Returns
boolean
Returns a boolean.

hasEventListener()
hasEventListener(
type,callback?,thisObject?):boolean
Defined in: src/event/CEventDispatcher.ts:197
whether the target presence of a listener with event type. it associate more registration parameters.

{string} event name.
callback?
Function = null
{Function} callback function of event register.

{any} The registered object.
Returns
boolean
Returns a boolean.

destroy()
destroy():
void
Defined in: src/gfx/renderJob/graph/RenderGraphPass.ts:397
Optional teardown hook called from graph.destroy() — release orphan Object3Ds / view quads / device resources that the pass owns directly.
Returns
void
Inherited from
setup()
setup(
b):void
Defined in: src/gfx/renderJob/graph/passes/SortedTransparentPass.ts:46
Allocate GPU resources, declare graph-level dependencies via b.read / b.write. Called from RenderGraph.compile() — setup is deferred from add() so add() call order doesn't constrain resource-dependency order. Forward references (reads to a resource a later-added pass creates) are resolved through a multi-round retry loop in compile().
Parameters
b
Returns
void
Overrides
execute()
execute(
ctx):void
Defined in: src/gfx/renderJob/graph/passes/SortedTransparentPass.ts:59
Execute the pass for one frame. Implementations build command encoders via ctx.view.engine3D.context3D.gpuContext, read inputs via ctx.get('<name>'), and submit GPU work.
Parameters
ctx
Returns
void
