| 15 | +# Week 04 Progress Report by Aditya Kumar Singh |
| 16 | + |
| 17 | +**Project:** [Sugarizer](https://github.com/llaske/sugarizer) |
| 18 | +**Mentors:** [Lionel Laské](https://github.com/llaske) |
| 19 | +**Assisting Mentors:** [Samarth Bagga](https://github.com/SamarthBagga) |
| 20 | +**Reporting Period:** 2025-05-30 - 2025-06-05 |
| 21 | + |
| 22 | +--- |
| 23 | + |
| 24 | +## Goals for This Week |
| 25 | + |
| 26 | +- **Goal 1:** Add a model selection palette UI to toggle between models. |
| 27 | +- **Goal 2:** Integrate the Human-body model into the paint activity and set the Human-body human model as the default view. |
| 28 | +- **Goal 3:** Refactor and improve naming conventions for bones in the skeleton model. |
| 29 | +- **Goal 4:** Localize the Human Body Activity using i18next.js, supporting English and French. |
| 30 | + |
| 31 | + |
| 32 | +--- |
| 33 | + |
| 34 | +## This Week’s Achievements |
| 35 | + |
| 36 | +1. **Model Palette Implementation** |
| 37 | + - Developed a new model selection palette in the UI allowing users to switch between: |
| 38 | + - Human body |
| 39 | + - Skeleton |
| 40 | + - Organs |
| 41 | + - Set the Human body as the default model loaded on activity start. |
| 42 | + - Palette updates the 3D scene dynamically without requiring a full reload. |
| 43 | +  |
| 44 | + |
| 45 | + |
| 46 | +2. **Human-Body Model Paint Integration** |
| 47 | + - Integrated the Human body model with the interactive paint activity. |
| 48 | + - Ensured hierarchical structure for smooth interactivity and logical mesh grouping |
| 49 | +  |
| 50 | + |
| 51 | + |
| 52 | +3. **Improved Bone Naming in Skeleton Model** |
| 53 | + - Refactored the skeletal model for accurate and educational naming: |
| 54 | + - Replaced generic labels like “Lower Leg” with specific names like **Tibia** and **Fibula**. |
| 55 | + - Split forearm into **Radius** and **Ulna**, adjusting geometry and mesh positions. |
| 56 | + |
| 57 | + |
| 58 | + |
| 59 | +4. **Implemented i18next.js to support internationalization.** |
| 60 | + - Implemented **i18next.js** to support internationalization. |
| 61 | + - Completed full translation of Human Body Activity in **English** and **French**. |
| 62 | + - Translation files follow standard .json structure for easy future expansion. |
| 63 | + - Example image for French: |

| 69 | +## Challenges & How I Overcame Them |
| 70 | + |
| 71 | +- **Challenge:** Naming skeleton bones accurately without anatomical overlap. |
| 72 | + **Solution:** Cross-referenced medical diagrams and validated model mesh mapping manually in Blender. |
| 73 | + |
| 74 | +--- |
| 75 | + |
| 76 | +## Key Learnings |
| 77 | + |
| 78 | +- Deepened understanding of scene management in Three.js and optimized mesh rendering for performance. |
| 79 | +- Gained experience in internationalization using i18next.js |
| 80 | +- Developed more precise anatomical terminology awareness and importance of educational clarity. |
| 81 | + |
| 82 | +--- |
| 83 | + |
| 84 | +## Next Week’s Roadmap |
| 85 | + |
| 86 | +- Write Weekly Blog Post summarizing progress, screenshots, and key learnings. |
| 87 | +- Fix Organs model. Distance between eyes and mouth seems to be more than required, reduce that and see if there is some alignment issue. |
| 88 | +- Integrate the full human body model into the paint activity to allow direct interaction and labeling across complete anatomy. |
| 89 | +- Merge Paint and Learn mode to show a popup at bottom of screen when user click a part |
