## Definition
|
||
visionOS 应用的多窗口管理模式，基于 WindowGroup 场景类型，支持 single-instance 窗口、volumetric 展示和空间场景管理。
|
||
|
||
## Window Types
|
||
- **Unique Windows（单实例窗口）**：应用主窗口，每次只存在一个实例
|
||
- **Volumetric Presentations（空间展示）**：在 3D volume 内呈现的辅助内容窗口
|
||
- **Spatial Scenes（空间场景）**：完整的 3D 空间应用场景定义
|
||
|
||
## Core Patterns
|
||
- **WindowGroup Management**：通过 WindowGroup 管理同类型窗口的生命周期
|
||
- **Glass Background Effects**：每个窗口默认带有 Liquid Glass 风格的毛玻璃背景
|
||
- **Spatial Presentation Hierarchy**：窗口之间的空间层级关系管理
|
||
- **Presentation State**：SwiftUI 状态驱动的窗口展示模式切换
|
||
|
