+
+## How to Generate More Iterations
+
+### Generating Iterations 6-12 (Intermediate Level)
+
+To continue with intermediate-level visualizations (textures, controls, particles):
+
+**Manual Agent Deployment:**
+
+```javascript
+// Deploy 7 agents for iterations 6-12
+// Each focuses on intermediate techniques:
+// - Iteration 6: Texture mapping
+// - Iteration 7: OrbitControls interaction
+// - Iteration 8: Advanced particles
+// - Iteration 9: Geometry manipulation
+// - Iteration 10: Post-processing (bloom)
+// - Iteration 11: Object hierarchies
+// - Iteration 12: Advanced lighting
+```
+
+**Command Pattern:**
+The `/project:infinite-web` command is not yet registered, but you can manually deploy agents using the Task tool with the same pattern we used today.
+
+### Example: Generate Iteration 6 (Texture Mapping)
+
+```javascript
+Task({
+    subagent_type: "general-purpose",
+    description: "Three.js viz 6: Texture mapping",
+    prompt: `
+    **TASK: Generate Three.js Visualization #6 - Intermediate Level**
+
+    **Learning Focus:** Texture loading, UV mapping, normal maps
+
+    **Assigned URL:** https://threejs.org/examples/#webgl_materials_texture_filters
+
+    **Requirements:**
+    1. Create file: threejs_viz/threejs_viz_6.html
+    2. Fetch and learn from the assigned URL (texture filters example)
+    3. Implement TextureLoader to load textures
+    4. Apply textures to 3D objects
+    5. Demonstrate UV mapping
+    6. Show different texture filter modes
+    7. Add normal maps for depth
+
+    **Deliverable:** Self-contained HTML file demonstrating texture techniques
+    `
+})
+```
+
+### Scaling to 20+ Iterations
+
+**Batch Deployment Strategy:**
+
+1. **Iterations 1-5:** Foundation (✅ Complete)
+2. **Iterations 6-12:** Intermediate (7 agents)
+   - Deploy in 2 waves: 4 agents, then 3 agents
+3. **Iterations 13-18:** Advanced (6 agents)
+   - Custom shaders, GLSL, advanced techniques
+4. **Iterations 19-25:** Expert (7+ agents)
+   - WebGPU, ocean shaders, compute particles
+
+### Infinite Mode Concept
+
+For continuous generation until context limits:
+
+1. **Wave 1** (5 agents): Foundation techniques ✅
+2. **Wave 2** (4 agents): Intermediate textures/controls
+3. **Wave 3** (4 agents): Intermediate particles/post-processing
+4. **Wave 4** (3 agents): Advanced shaders
+5. **Wave 5** (3 agents): Advanced materials/lighting
+6. **Wave 6+**: Expert WebGPU and cutting-edge techniques
+
+---
+
+## The Web-Enhanced Pattern
+
+### Core Concept
+
+The Web-Enhanced Infinite Agentic Loop pattern extends the original infinite loop by adding **progressive web-based learning** where each iteration:
+
+1. **Fetches** a specific web resource (documentation, example, tutorial)
+2. **Learns** 1-3 specific techniques from that source
+3. **Applies** the learning to create unique visualization
+4. **Documents** the web source and what was learned
+
+### Key Phases
+
+#### Phase 0: Initial Web Priming
+- Fetch 3-5 foundational resources before any generation
+- Build mental model of the domain (Three.js fundamentals)
+- Extract core concepts, patterns, best practices
+- Synthesize into comprehensive knowledge base
+
+#### Phase 1: Specification + Web Context Analysis
+- Read specification file (threejs_visualization_progressive.md)
+- Parse URL strategy file (threejs_url_strategy.json)
+- Understand how web research enhances each iteration
+- Plan web integration strategy
+
+#### Phase 2: Directory Reconnaissance + URL Tracking
+- Analyze existing output directory
+- Track which URLs have been used (avoid duplication)
+- Build USED_URLS list from file footers/comments
+- Identify knowledge gaps for new web research
+
+#### Phase 3: Web-Enhanced Iteration Strategy
+- Map iteration numbers to URL difficulty levels
+- Assign specific web sources to each planned iteration
+- Ensure progressive difficulty curve
+- Plan both pre-defined URLs and dynamic search fallback
+
+#### Phase 4: Parallel Web-Enhanced Agent Coordination
+Each agent receives:
+- **Spec Context**: Full specification + priming knowledge
+- **Web Assignment**: Specific URL to fetch and learn from
+- **Used URLs List**: Prevent duplication
+- **Iteration Number**: Unique identifier
+- **Integration Directive**: How to synthesize web learning
+
+#### Phase 5: Web Integration Quality Assurance
+- Verify web source attribution in each file
+- Validate that learning was actually applied (not just cited)
+- Check for genuine improvement evidence
+- Ensure spec compliance maintained
+- Confirm uniqueness across all iterations
+
+### Progressive URL Difficulty Strategy
+
+```
+Foundation (1-5)      → Basic concepts, scene setup
+     ↓
+Intermediate (6-12)   → Textures, controls, particles
+     ↓
+Advanced (13-18)      → Custom shaders, GLSL, physics
+     ↓
+Expert (19+)          → WebGPU, compute shaders, ocean effects
+```
+
+### Advantages Over Original Pattern
+
+1. **Knowledge Accumulation**: Each iteration builds on web discoveries
+2. **Progressive Sophistication**: Natural complexity curve
+3. **Real-World Learning**: Uses actual documentation and examples
+4. **Quality Sources**: Curated URLs ensure valuable learnings
+5. **Documentation**: Clear attribution enables learning from code
+6. **Uniqueness**: Different URLs guarantee different approaches
+

+- How should shaders or materials be structured?
+
+**Visual Design:**
+- What makes this visualization aesthetically compelling?
+- How does lighting enhance the scene?
+- What camera angle best showcases the technique?
+- How can animation improve the experience?
+
+**Progressive Building:**
+- How does this iteration advance beyond previous ones?
+- What new complexity is introduced?
+- Can I combine techniques from earlier iterations?
+- What's the next logical step in the learning path?
+
+**Quality Assurance:**
+- Does the code clearly demonstrate the learned technique?
+- Is the web source properly attributed?
+- Would someone learn from viewing this example?
+- Is the implementation unique and creative?
+
+## Success Criteria
+
+A successful Three.js iteration:
+- **Runs Perfectly**: No errors, smooth 60fps animation
+- **Demonstrates Learning**: Clear application of web-sourced technique
+- **Looks Beautiful**: Visually engaging and well-crafted
+- **Is Self-Contained**: Single HTML file works standalone
+- **Documents Sources**: Clear attribution and learning explanation
+- **Shows Progression**: Builds on previous iterations appropriately
+- **Teaches Others**: Code quality that others can learn from
+
+Generate Three.js visualizations that showcase the power and beauty of modern 3D web graphics while demonstrating genuine progressive learning from web resources.
