1 | # Tech-Tree - Recursive Exploration Through Humans' Greatest Inventions
2 |
3 | A web app (ts + rust) that recursively analyzes engineering concepts from Wikipedia api, extracting fundamental building blocks and their interconnections to create interactive 3D knowledge trees... allowing builders to explore the relationships between different engineering concepts.
4 |
5 | ## Architecture Overview

18 | └──────────────────┘
19 | ```
20 |
21 | ## Key Features
22 |
23 | - **Recursive Analysis**: Automatically discovers and analyzes related engineering concepts
24 | - **3D Visualization**: Interactive WebGL-based tree structures with hierarchical node layouts
25 | - **Semantic Extraction**: Advanced NLP for identifying engineering principles from Wikipedia content
26 | - **Real-time Interaction**: Drag-to-rotate, scroll navigation, and clickable node exploration
27 | - **Confidence Scoring**: AI-driven confidence metrics for extracted principles
28 | - **Caching System**: Intelligent caching for performance optimization
29 |
30 | ## Technology Stack
31 |
32 | ### Backend (Rust)
33 | - **Framework**: Axum for high-performance HTTP handling
34 | - **Analysis Engine**: Custom semantic analyzer with Wikipedia integration
35 | - **Caching**: In-memory caching system for API responses
36 | - **Architecture**: Modular design with separate analyzer, API, and caching layers
37 |
38 | ### Frontend (React/TypeScript)
39 | - **3D Engine**: Three.js for WebGL rendering
40 | - **UI Framework**: Material-UI with custom glass-morphism styling
41 | - **State Management**: React hooks with local state management
42 | - **Visualization**: Hierarchical tree layouts with curved connection lines

73 |
74 | ## API Endpoints
75 |
76 | ### Core Analysis
77 | - `POST /api/analyze` - Analyze a single engineering term
78 | - `POST /api/analyze/recursive` - Perform recursive analysis with depth control
79 | - `GET /api/search/suggestions` - Get search suggestions for terms
80 |
81 | ### System Information
82 | - `GET /api/cache/stats` - Cache performance metrics
83 | - `GET /api/health` - System health check
84 |
85 | ## Data Flow
86 |
87 | 1. **Input Processing**: User submits engineering term via frontend interface
88 | 2. **Wikipedia Retrieval**: Backend fetches relevant Wikipedia pages
89 | 3. **Semantic Analysis**: NLP engine extracts engineering principles and relationships
90 | 4. **Tree Construction**: Hierarchical data structure built with confidence scoring
91 | 5. **3D Rendering**: Frontend renders interactive WebGL visualization
92 | 6. **User Interaction**: Real-time exploration of knowledge relationships
93 |
94 | ## Setup Instructions
95 |
96 | ### Backend Development
97 | ```bash
98 | cd backend
99 | cargo run --release
100 | # Server starts on http://localhost:8080
101 | ```
102 |
103 | ### Frontend Development
104 | ```bash
105 | cd frontend
106 | npm install
107 | npm start
108 | # Development server starts on http://localhost:3000
109 | ```
110 |
111 | ### Production Build
112 | ```bash
113 | cd frontend
114 | npm run build
115 | # Serves static files through backend in production
116 | ```
117 |
118 | ## Configuration
119 |
120 | ### Backend Configuration (Cargo.toml)
121 | - Axum for HTTP server
122 | - Tokio for async runtime
123 | - Serde for JSON serialization
124 | - Custom semantic analysis crates
125 |
126 | ### Frontend Configuration (package.json)
127 | - Three.js for 3D graphics
128 | - Material-UI for component library
129 | - TypeScript for type safety
130 | - React 18+ with modern hooks
131 |
132 | ## Performance Characteristics
133 |
134 | - **Analysis Speed**: ~500ms average for single-term analysis
135 | - **Memory Usage**: Intelligent caching with configurable limits
136 | - **Rendering**: 60fps WebGL visualization with optimized geometry
137 | - **Scalability**: Handles recursive analysis up to 5 levels deep
138 |
139 | ## Development Guidelines
140 |
141 | ### Code Organization
142 | - Modular Rust backend with clear separation of concerns
143 | - React components follow single-responsibility principle
144 | - TypeScript interfaces for all data structures
145 | - Comprehensive error handling and logging
146 |
147 | ### Testing Strategy
148 | - Unit tests for core analysis algorithms
149 | - Integration tests for API endpoints
150 | - Frontend component testing with React Testing Library
151 | - Performance benchmarks for analysis engine
