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.
