WasmGPU.run

Summary

WasmGPU.run starts the engine frame loop and invokes your callback once per animation frame. Inside the callback, you typically update scene state and issue one render call for the active scene/camera. The loop also feeds PerformanceStats (if enabled) with per-frame timing data.

Syntax

WasmGPU.run(callback: (dt: number, time: number, wgpu: WasmGPU) => void): void
wgpu.run(callback);

Parameters

Name Type Required Description
callback (dt: number, time: number, wgpu: WasmGPU) => void Yes Frame callback receiving delta-time seconds, absolute-time seconds, and the active engine instance.

Returns

void - Starts the RAF loop; no value is returned.

Example

const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const scene = wgpu.createScene([0.04, 0.05, 0.08]);
const camera = wgpu.createCamera.perspective({ fov: Math.PI / 3, aspect: canvas.width / Math.max(1, canvas.height), near: 0.1, far: 1000 });
camera.position[2] = 4;
wgpu.run((dt, time, engine) => {
    camera.position[0] = Math.sin(time) * 0.5;
    engine.render(scene, camera);
});
