Interface WebGPURendererEvents

Lifecycle, device, render, and error events emitted by WebGPURenderer.

The event names mirror the backend-neutral renderer contract so viewer and Studio integrations can consume WebGPU and WebGL through the same public event surface.

interface WebGPURendererEvents {
    onContextLost: EventEmitter<WebGPURenderer, Event>;
    onContextRestored: EventEmitter<WebGPURenderer, void>;
    onError: EventEmitter<WebGPURenderer, RendererError>;
    onRendererDestroyed: EventEmitter<WebGPURenderer, boolean>;
    onRendererStarted: EventEmitter<WebGPURenderer, void>;
    onRendererStopped: EventEmitter<WebGPURenderer, void>;
    onViewerAttached: EventEmitter<WebGPURenderer, Viewer>;
    onViewerDetached: EventEmitter<WebGPURenderer, Viewer>;
    onViewRendered: EventEmitter<WebGPURenderer, View>;
}
