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:

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.
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.
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.
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.
Use Advanced Features:
- Utilize new RealityKit APIs to import 2D vector graphics and make them spatial.
- Integrate RealityKit's physics system for interactive elements.
