pipelineSets

• get pipelineSets(): number

  Pipeline sets compiled (one per surface format, however many engines).

  Returns number

createEngine

• createEngine(
      canvas: HTMLCanvasElement,
      options: {
          clusterCount: number;
          edgeCount: number;
          nodeCount: number;
          seed: number;
      },
  ): WasmCharturboEngineBackend

  Engine backend on canvas (used by Charturbo.create(canvas, { device })). Throws a CharturboInitError when the canvas cannot be attached, or an Error after dispose().

  Parameters

  • canvas: HTMLCanvasElement
  • options: { clusterCount: number; edgeCount: number; nodeCount: number; seed: number }

  Returns WasmCharturboEngineBackend

dispose

• dispose(): void

  Releases this handle (see the module docs: live engines keep the GPU device until disposed).

  Returns void

Staticcreate

• create(options?: CharturboDeviceOptions): Promise<CharturboDevice>

  Requests the shared adapter + device. Throws a CharturboInitError ('no-webgpu', 'adapter', 'device', 'wasm') like Charturbo.create.

  Parameters

  • Optionaloptions: CharturboDeviceOptions

  Returns Promise<CharturboDevice>

StaticfromBackend

• fromBackend(
      handle: WasmGpuDeviceBackend,
      factory: CharturboDeviceEngineFactory,
  ): CharturboDevice

  Wraps an existing device handle and engine factory (tests, custom builds).

  Parameters
