Help me make a custom spatial template with people positioned in a circle around a volumetric app, but everyone facing directly away from the volumetric app

To create a custom spatial template with people positioned in a circle around a volumetric app, but everyone facing directly away from the app, you can follow these steps:

1. Define the Custom Spatial Template: Start by creating a struct that conforms to the SpatialTemplate protocol. This struct will define the seats and their positions relative to the shared app.

2. Position the Seats: Arrange the seats in a circle around the volumetric app. You can use trigonometric functions to calculate the positions of the seats in a circular pattern.

3. Set Seat Directions: By default, seats face towards the center of the app. You will need to override this to make the seats face away from the app. Use the lookingAt method to set the direction each seat should face.

Here is a simplified example in Swift:

struct CustomCircleTemplate: SpatialTemplate {
    var elements: [SpatialTemplateElement] {
        let numberOfSeats = 8
        let radius: Float = 2.0
        var seats: [SpatialTemplateElement] = []
        
        for i in 0..<numberOfSeats {
            let angle = Float(i) * (2.0 * .pi / Float(numberOfSeats))
            let x = radius * cos(angle)
            let z = radius * sin(angle)
            let position = SIMD3<Float>(x, 0, z)
            
            // Create a seat facing away from the center
            let seat = SpatialTemplateElement.seat(position: position, lookingAt: SIMD3<Float>(-x, 0, -z))
            seats.append(seat)
        }
        
        return seats
    }
}

Key Points from the Session

• System Templates: The session mentions several built-in system templates like the side-by-side, conversational, and surround templates. The surround template places participants in a circle around a shared volume, which is similar to what you want but with participants facing the app. Customize spatial Persona templates in SharePlay (00:02:36).

• Custom Templates: You can create custom spatial templates to have complete control over the placement of spatial Personas. This is useful for unique social experiences on visionOS. Customize spatial Persona templates in SharePlay (00:03:29).

• Seat Directions: You have full control over the direction each seat faces. Use the lookingAt method to orient seats appropriately. Customize spatial Persona templates in SharePlay (00:30:56).
