Signature Design Concept

The Windy-Car app will feature an interactive 3D racing hub as the homepage. Users will enter a virtual garage where they can see their cars in a dynamic environment. Using @react-three/fiber and @react-three/drei, the garage will allow users to rotate and zoom into their cars, customize them in real-time, and select races. The environment will change based on the time of day, using gsap for smooth transitions and lighting effects. Hovering over different parts of the garage will reveal interactive elements like race selection, car customization, and leaderboard access.

Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model, providing a layered depth effect as users scroll through the app. Decorative elements like racing flags and speed lines will move at different speeds, creating an immersive experience. Internal pages such as settings and profiles will adopt a "static" model for clarity and ease of use.

Non-Functional Requirements

• The app must support real-time multiplayer functionality with minimal latency.
• It should be compatible with both iOS and Android platforms.
• The app must handle high traffic volumes during peak times without performance degradation.
• Ensure data security and privacy for all user information.

Tech Stack

• Frontend: React for Web, React Native for mobile app
• Backend: Python, FastAPI
• Database: MySQL or MariaDB, use alembic for migrations
• AI Models: GPT 5.4 for user-friendly responses
• AI Tools: Litellm for LLM Routing, Langchain
• Local Orchestration: Docker, docker-compose
• Server-side Orchestration: Kubernetes

Assumptions and Constraints

• The app will require an internet connection for multiplayer features.
• Users will need to create an account to access all features.
• The app will be designed to support English as the primary language, with potential for localization in the future.
