R&D prototype

Meije Render Lab

An R&D prototype by Studio Meije to benchmark rendering techniques on Apple Vision Pro. The same scene runs on the headset with RealityKit, and on a PC with Unreal Engine, streamed with NVIDIA CloudXR.

The courtyard, the house and the car rendered by RealityKit on Apple Vision Pro

One Scene. Two Techniques.

We built one complex environment, a furnished house, a courtyard, foliage and a car, and rendered it two ways to compare visual quality, lighting and the trade-offs of each approach on the same headset.

Local · RealityKit

Rendered on the headset.

RealityKit renders the whole courtyard on Vision Pro with baked lightmaps, image-based light and real-time lantern lights. It shows how far on-device rendering goes, with no PC and no network.

Cloud · Unreal Engine

Rendered on a PC.

Unreal Engine renders the same scene on an NVIDIA RTX PC and streams it to Vision Pro with NVIDIA CloudXR and foveated streaming. It shows what remote rendering adds, and what it needs in return: a PC and a good network.

Compare Side by Side.

Both versions share the same controls, so you can look at the same detail in each and judge the difference yourself.

Paint

Repaint the car.

Choose one of eight paints and see how each technique handles the reflections and the light.

Viewpoints

Change your point of view.

Jump between four points around the car: side, rear, front right and front left.

Stream From Your PC.

The streamed version needs the free Meije Render Lab host, which runs the scene in Unreal Engine on a Windows PC.

What you need

  • A Windows 10 or 11 PC with an NVIDIA RTX graphics card and an up-to-date driver.
  • The PC and Apple Vision Pro on the same network. A wired PC and 5 GHz or 6 GHz Wi-Fi for the headset work best.
  • Meije Render Lab installed on Apple Vision Pro.
Download the Windows host

Get started

  1. Download and extract the host into a folder on your PC.
  2. Run Configure Firewall once. It lets the host reach your Vision Pro on your local network only.
  3. Start the host normally, not as administrator.
  4. On Vision Pro, choose Stream from Your PC, then Connect. The first time, look at the QR code on your PC to pair the headset.

An R&D Project by Studio Meije.

Meije Render Lab helps us benchmark rendering techniques on Apple Vision Pro: what runs well on the headset, and what is worth streaming from a PC.

Matthieu created the 3D artwork of this scene, the car, the house and the courtyard, during his internship at Studio Meije. The project is part of that internship and of Studio Meije’s R&D into local and cloud rendering for Vision Pro.
