Properties
Optionalalpha
Optionalclear
Clear the target before drawing. Set false when several viewport passes share a target.
Readonlyengine
Engine captured at task creation.
Optionalexecution
Runtime frame-graph execution gate, default true. When false, the frame graph keeps the task recorded
and its resources alive but skips every pass or built-in execute() call for that frame. This is
independent from any task-specific enabled state whose disabled transition may still execute work.

f

Readonlyname

Optional Readonlyscene
Owning scene for scene-bound tasks. Undefined for scene-less standalone frame graphs.

Methods
dispose
-
Free all GPU resources owned by this task.
Returns void
Optionalexecute
-
Optional fast path for built-in tasks that execute without recorded Pass objects.
Returns number
record
-
Called once when the frame graph is built. Must complete synchronously.
Returns void
update
-
Recompute and upload the uniforms of every sub-pass (CoC, blurs, merge).
Returns void
A composite depth-of-field post-process task: circle-of-confusion → CoC-weighted blur pyramid → merge.
