how do I make a spatial notes on board app

To create a spatial notes or drawing app using RealityKit, you can follow the steps outlined in the session Build a spatial drawing app with RealityKit. Here is a summary of the key steps:

1. Set Up Spatial Tracking:

   • Use RealityKit's spatial tracking APIs to understand hand and environment data.
   • Set up hand anchors in VisionOS to track hand poses as you pinch and move your hand.
   • Use anchor entities to affix RealityKit content to AR anchors, such as thumb tip and index fingertip anchors.

2. Build a User Interface:

   • Create a UI to control the brush and canvas using SwiftUI.
   • Customize the UI with advanced hover effects.
   • Implement a palette view to configure the shape and color of the brush.

3. Generate Brush Geometry:

   • Use RealityKit APIs to generate brush geometry efficiently with Metal.
   • Customize brush strokes, including solid brush types and sparkle brushes.
   • Adjust brush properties like color and thickness.

4. Create a Splash Screen:

   • Design an engaging splash screen with dynamic textures and spatial UI elements.
   • Ensure the splash screen provides a quick setup process for users to start drawing.

5. Use Advanced Features:

   • Utilize new RealityKit APIs to import 2D vector graphics and make them spatial.
   • Integrate RealityKit's physics system for interactive elements.

For a detailed walkthrough, you can refer to the following chapters in the session:

• Set up spatial tracking
• Build a spatial user interface
• Generate brush geometry
• Create a splash screen

These steps will guide you through creating a compelling spatial notes or drawing app using RealityKit on VisionOS.
