How do I render a stereoscopic image in RealityKit?

To render a stereoscopic image in RealityKit, you can follow these steps:

1. Duplicate Screen Rendering for Each Eye: You need to update your game loop to render the scene separately for each eye. This involves duplicating the screen rendering process for both the left and right eyes.

2. Use Vertex Amplification: For better performance, you can use vertex amplification to render both eyes with the same draw calls. This technique helps in efficiently managing the rendering workload.

3. Adjust Camera Matrices: Set the appropriate camera matrices for each eye. This ensures that each eye gets a slightly different view of the scene, creating the stereoscopic effect.

4. Encode Rendering Commands: Encode the rendering commands to the color and depth textures of each view. This step is crucial for ensuring that the rendered images for both eyes are correctly processed and displayed.

5. Head Tracking (Optional): To enhance the stereoscopic effect, you can add head tracking. By using ARKit, you can get the position of the player's head and adjust the camera position accordingly. This makes the scene look more immersive and realistic.
