The Latency Problem
Static images create hesitation. They fail to communicate form, fit, and texture. Conversely, most web 3D implementations are resource-heavy, disorienting, and lack utility.
GOAL: Prove that 3D can be a rigorous UX tool by focusing on controlled interaction, state-driven cameras, and 60FPS performance.

Optimization Log
State-Driven Interaction
Camera behavior is governed by explicit interaction states (IDLE, ORBIT, LOCKED) rather than ad-hoc controls. This prevents the user from "getting lost" in 3D space.
Frame Budgeting
High-cost physics simulations were deferred in favor of baked animations to ensure smooth performance on mid-range mobile devices.
Componentized Scene
Rendering logic, UI overlays, and interaction state are cleanly separated. The 3D view is just another React component, not a monolithic canvas takeover.
UX-Safe Constraints
Degrees of freedom were intentionally restricted. Users cannot flip the model upside down or zoom infinitely. Constraints breed clarity.
