What is AR Quick Look?
You’re probably already familiar with Quick Look, which lets you quickly peek at images, PDFs and spreadsheets in apps like Mail and Safari. Quick Look is a framework that does the heavy lifting for you. It essentially gives your app superpowers that allow it to support a wide selection of universal file formats.
Here’s the best part: Quick Look now offers support for USDZ and Reality file formats via its AR Quick Look feature.
AR Quick Look lets you showcase a virtual 3D model of a physical product within your local space. The model appears grounded in your environment, giving you a good sense of how the physical product looks.
Imagine you want to buy a new sofa. A shopping app with this technology would let you check out how various sofas actually look in your living room.
AR Quick Look achieves a high degree of realism by mimicking realistic lighting conditions in your local environment. It combines this lighting with soft shadows and physical-based rendering (PBR) materials that shine and reflect the local environment, just like the real thing.
Using AR Quick Look is as simple as providing it with the path to your USDZ or Reality content and letting it do its magic. And there are lots of nifty things you can do with it, too, as you’ll see next.
Apple Augmented Reality by Tutorials AR Quick Look features
At face value, AR Quick Look seems simple enough. When you dig deeper, however, you’ll notice that it comes with a bucket-load of insanely cool features.
Here’s a look at what’s inside:
- Anchors: Anchors allows you to anchor virtual content to various real-world surfaces. With the release of iOS 13, AR Quick Look supports horizontal surfaces like floors, ceilings, tables and chairs; vertical surfaces like walls; images including photos and posters; faces and objects like toys and consumer products.
- Occlusion: Occlusion allows the physical world to obscure virtual content based on its depth in relation to the real world. AR Quick Look currently offers occlusion for people and faces. This feature works only on certain devices.
- Physics, Forces and Collisions: Virtual content responds to the laws of physics. Gravity can make objects fall, and the objects can bounce and collide with one another.
- Triggers and Behaviors: Users can reach into AR and interact with objects to trigger events, animations and sounds.
- Realtime Shadows: Virtual content will cast realistic-looking shadows onto real- world surfaces. The quality of the shadows depends on the device’s capabilities. Low-end devices project shadows, while high-end devices use ray-traced shadows.
- High Dynamic Range, Tone Mapping and Color Correction: AR Quick Look samples the local environment in real-time and uses the results to control the virtual content’s brightness, color and tone. This lets objects blend in with their surroundings naturally.
- Camera Grain, Motion Blur and Depth of Field: Post-processing camera effects push the visual fidelity to the next level. Fast-moving objects blur, distant objects appear out of focus and adding a grain effect to crisp-looking virtual content makes it blend in with a typical grainy camera feed.
- Multi-Sampling and Specular Anti-aliasing: AR Quick Look anti-aliases the virtual content’s edges to smooth out pixelation. It also anti-aliases specular reflections to prevent flickering.
- Physically Based Rendering Clear Coat Materials: Apply super-realistic materials to virtual content so that your objects look exactly like their real-life counterparts.
- Ambient and Spatial Audio: Ambient sounds add another level of realism to virtual content. Objects produce spatially-accurate sound effects based on their location in physical space and their position relative to the camera.
- Integration and Customization: You can easily integrate AR Quick Look into Web, iOS, macOS and tvOS apps.
- Apple Pay: Apple Pay is fully integrated into AR Quick Look. The end-user can impulse-buy your products without leaving the AR experience.As you can see, AR Quick Look gives you the flexibility to make your products shine in AR. However, there are a few limitations to keep in mind while you work with it.
