Constructors

constructor

  • Create a new pool of workers. Workers will only be initialized on the first CSG operation, or after calling and waiting for initialize.

    Parameters

    • workerCount: null | number = null

      The wanted amount of workers. Note that this is a target, not a requirement. If all but one worker fails to be created, no error will be thrown.

    • workerPath: string = 'gypsum-manifold.worker.min.js'

      The path to the Gypsum<->Manifold worker script. Points to "gypsum-manifold.worker.min.js" by default.

    • manifoldPath: string = 'manifold.js'

      The path to the Manifold WASM bindings library. Points to "manifold.js" by default.

    Returns CSGPool

Properties

Private disposed

disposed: boolean = false

Private initLock

initLock: null | CallableFunction[] = null

Private jobs

jobs: Map<number, JobTuple> = ...

Private manifoldPath

manifoldPath: string

Private nextJobID

nextJobID: number = 0

Private wantedWorkerCount

wantedWorkerCount: number

Private workerPath

workerPath: string

Private workers

workers: null | WorkerArray = null

Methods

dispatch

  • Dispatch a tree of CSG operations to the best worker; first worker with the least amount of running jobs.

    Parameters

    Returns Promise<JobResult>

dispose

  • Destroys all resources associated with this pool. All jobs assigned to this pool are rejected, and all workers assigned to this pool are terminated. Does nothing if the pool is already disposed.

    Returns void

Private getBestWorker

  • Returns [bestWorkerIdx: number, bestWorker: WorkerTuple]

initialize

  • Initialize all the workers in this pool. Note that calling this is not neccessary, but is recommended to avoid stuttering, as this is called automatically on the first CSG operation.

    Returns Promise<void>

Private initializeImpl

Private initializeSingle

  • Parameters

    • displayID: number

    Returns Promise<void>

Private terminateWorkers
