设计用于自然拼读课堂的 3D 网页游戏：接住播放短元音的下落球体，含重力与粒子反馈。
我希望你充当一名专业的 Web 3D 游戏开发者兼教育技术专家。你的目标是为小学自然拼读课堂设计一款高保真度的 3D 互动原型游戏。 游戏名称：《Vowel Velocity: Phonetic Catch》。 游戏功能：场景包含一个开放的 3D 地形，用户可通过鼠标在 X 轴方向上控制一个大型篮子移动。从视口顶部开始，各种彩色几何球体以随机时间间隔向下掉落，并通过逼真的重力公式加速下落。每个球体在生成时会触发特定的音频文件（短元音音素，如 /æ/、/e/、/ɪ/）。当篮子成功接住球体时，会触发向上的粒子喷发效果以及轻微的屏幕震动效果。如果球体撞击地面，则会播放柔软材质的放气动画，随后重置。 设计风格：鲜明、风格化的极简主义。使用天蓝色背景与柔和的烘焙环境光照明。球体应具备有光泽的糖果质感，并采用明显且高对比度的霓虹色彩，以最大程度吸引儿童的视觉注意力。 所用技术：Three.js 用于场景渲染，Web Audio API 用于低延迟的空间化音频播放，Cannon.js 用于刚体物理的重力模拟与碰撞检测。
I want you to act as an Expert Web 3D Game Developer and Educational Technologist. Your goal is to design a high-fidelity 3D interactive prototype for a primary school phonics classroom game. Game Name: 《Vowel Velocity: Phonetic Catch》. Game Function: The scene features an open 3D landscape where a large basket is controlled by the user via mouse movement along the X-axis. From the top of the viewport, various colorful geometric spheres fall downwards at random intervals, accelerated by a realistic gravity formula. Each sphere triggers a specific audio file (short vowel sounds like /æ/, /e/, /ɪ/) upon spawning. When the basket successfully intercepts a sphere, it triggers an upward particle emission and a subtle screen-shake effect. If a sphere hits the ground, it undergoes a soft-body deflation animation and resets. Design Style: Vibrant, stylized minimalism. Use a sky-blue background with soft, baking-baked ambient lighting. The spheres should possess a glossy, candy-like texture with distinct, high-contrast neon colors to maximize children's visual engagement. Technologies Used: Three.js for scene rendering, Web Audio API for low-latency spatialized audio playback, and Cannon.js for rigid-body gravity and collision detection.
