Use three.js to build a 3D interactive display of an aircraft engine on a webpage. 
Please refer to Jigspace's interaction design philosophy to achieve a realistic model with near 1:1 high-fidelity restoration, fully preserving material and texture details such as metal, pipelines, and blades. Interactive features must include: step-by-step disassembly animation, exploded view of components, and part descriptions and principle explanations triggered by click or hover. 
Overall, it must support smooth camera control and friendly human-computer interaction, ensuring a smooth experience on the web that fully showcases the engine's structure and working principles.
