Interactive 3D jet engine cutaway with view modes

GOAL: Create a visually impressive interactive 3D cutaway jet engine experience in Three.js. MOTION: The result should feel like a premium technical visualization or futuristic engineering showcase. The first few seconds must have a strong wow effect and immediately hook the viewer. Core idea: Build a detailed jet engine in 3D with a clean outer shell, and let the viewer explore the inside through cutaway, x-ray, and exploded-style views. Main requirements: Build a full 3D jet engine from scratch in code No pre-made 3D models Use Three.js Prefer a single HTML file unless a few small extra files are truly necessary The project must run locally in the browser The engine should include: front fan blades compressor stages combustion chamber turbine stages exhaust section outer shell / nacelle internal shaft structure visible airflow path Interactions / modes: assembled mode cutaway mode x-ray mode exploded view mode airflow visualization on/off throttle or power slider auto-rotate camera option orbit controls Animation ideas: engine startup sequence fan spins up first inner stages accelerate combustion chamber ignites hot glowing section appears in the core exhaust flow becomes visible subtle vibration / mechanical life Visual quality: polished lighting premium materials good contrast between outer shell and internals smooth transitions between modes readable labels or callouts for key engine parts cinematic presentation strong sense of depth The first seconds should feel especially strong: for example, begin with a clean hero shot of the engine, then smoothly reveal the cutaway and ignite the core. Make it feel detailed, technical, and visually satisfying rather than toy-like.
