Signature Design Concept

The CommerceHub landing page will feature an interactive 3D marketplace map using @react-three/fiber and @react-three/drei. Users can navigate through a virtual marketplace where each product category is represented as a distinct 3D building. Hovering over a building reveals product highlights, and clicking on it zooms into a detailed view of the category's offerings. The map will dynamically adjust to user interactions, providing a unique and engaging browsing experience.

Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model, with layered depth effects as users scroll. Decorative elements will translate at different speeds, creating a visually rich storytelling experience. Internal pages such as dashboards and settings will adopt a "static" model for clarity and ease of navigation.
