`Static` requestSharedDevice

requestSharedDevice(): Promise<GPUDevice>
Returns a shared GPUDevice, initialising it on the first call. All renderers share the same adapter and device to avoid exhausting browser GPU resource limits. The device is requested with timestamp-query enabled if the adapter supports it, so profiling-capable renderers (e.g. DmdRenderer) can use that feature without a separate device request.

Returns Promise<GPUDevice>
Inherited from LayerRenderer.requestSharedDevice
- Defined in src/renderers/renderer.ts:25

`Static` releaseSharedDevice

releaseSharedDevice(): void
Clear the cached adapter and device. Call this during cleanup or in tests.

Returns void
