Building Augmented Reality Apps in RealityKit & ARKit

Use ray casting to detect horizontal planes and tap to place a box as a model entity via ARAnchor and anchor entity, adding objects to the scene.

Replace the air anchor with an anchor entity and use ray casting results to place the model entity, then add the anchor to the scene.

Load a lunar rover animated model from a reality file into a scene via an anchor, and ensure only one rover appears by guarding taps.

Implement occlusion in RealityKit by using an occlusion material on a movable box anchored to a horizontal plane, so the box hides parts of the robot model.

Display images as textures on a 3D box by loading a texture resource, applying an unlit material, and mapping the image to all faces in RealityKit.

Learn how to implement collision detection in RealityKit by setting a trigger collision component, subscribing to begin and end collision events, and changing a box material during contact.

Define collision groups and masks to control interactions, creating a box group and a sphere group with subtracting filters so boxes collide only with boxes and spheres only with spheres.

Refactor your AR project by introducing a movable entity that encapsulates mesh, materials, physics, and collision, enabling quick creation of boxes and spears with configurable shape and color.

Create an augmented reality measuring app with RealityKit and ARKit that lets you place two points, view their distance, and reset to measure again in horizontal and vertical orientations.

Set up the initial AR project by adding a coaching overlay and a coordinator, configure world tracking, and create a UI with measurement and reset buttons to guide surface discovery.

Explore image detection in augmented reality by replacing a real image or card with a virtual object, such as a wristwatch, and trigger animations for diverse uses.

Detect a poster image and display a video on a RealityKit plane anchored to the image, using ARKit and loading the video from the bundle.

Create a spotlight in RealityKit by anchoring a light, setting inner and outer cone angles, and a 10-meter radius. Observe shadows and adjust colors and intensity to see the effect.
