To build a spatial drawing app with RealityKit, you can leverage its powerful 3D capabilities alongside SwiftUI and ARKit to create an immersive user experience. The app can include features such as spatial tracking to understand hand and environment data, a customizable user interface for brush and canvas control, and the ability to generate brush geometry using RealityKit's new APIs.
For example, you can set up spatial tracking to recognize hand poses and movements, allowing users to draw by pinching their fingers in the air. The app can also feature a palette view for customizing brush types and styles, with options for solid and sparkle brushes. Additionally, you can create an engaging splash screen with dynamic textures and spatial UI elements.
