How can I build a custom spatial template with 5 seats, spaced 1 meter apart from each other in an arc?

To build a custom spatial template with 5 seats, spaced 1 meter apart from each other in an arc, you can follow these steps:

1. Define the Template: Create a struct that conforms to the spatial template protocol. This struct will contain an array of template elements, each representing a seat.

2. Position the Seats: Seats are positioned relative to the shared app. You can set the x and z offsets to place the seats in the desired positions. For an arc, you will need to calculate the positions based on the arc's radius and angle.

3. Spacing and Orientation: Ensure that the seats are spaced at least 1 meter apart to avoid crowding. You can also set the direction each seat should face.

Here is a simplified example based on the provided context:

struct ArcTemplate: SpatialTemplate {
    var elements: [SpatialTemplateElement] {
        let radius: Float = 4.0 // Distance from the app
        let angleIncrement: Float = .pi / 4 // 45 degrees in radians
        var seats: [SpatialTemplateElement] = []
        
        for i in 0..<5 {
            let angle = angleIncrement * Float(i - 2) // Center seat at 0, others at -2, -1, 1, 2
            let xOffset = radius * sin(angle)
            let zOffset = radius * cos(angle)
            let seat = SpatialTemplateElement(position: SIMD3<Float>(xOffset, 0, zOffset))
            seats.append(seat)
        }
        
        return seats
    }
}

Key Points from the Session:

• Positioning Seats: Seats are defined relative to the position of the shared app. For example, the first seat can be placed directly in front of the app with an x offset of 0 and a z offset of 4 meters. Subsequent seats can be positioned with x offsets of ±1 meter to the left and right (Customize spatial Persona templates in SharePlay).

• Spacing: Ensure seats are at least 1 meter apart to avoid crowding and ensure visibility of spatial Personas (Customize spatial Persona templates in SharePlay).

• Orientation: You can control the direction each seat faces using methods like looking at or aligned with (Customize spatial Persona templates in SharePlay).
