3. Description
------------------------------------------------------------
This dataset accompanies the paper *Fabrication-aware structural form-finding for additive manufacturing: An equilibrium-based approach*
and contains all relevant data for reproducing and understanding the workflow from computational form finding to physical fabrication.

Included files:
1. Grasshopper Definition (.ghx) — The parametric model used for form finding.
2. OBJ Files (.obj) — Generated and laser-scanned geometries for comparison.
3. MP4 Files (.mp4) — Videos documenting the additive manufacturing / robotic printing process.

------------------------------------------------------------
4. File Overview
------------------------------------------------------------
| File Type | Folder / File Name Example | Description |
|------------|----------------------------|--------------|
| .ghx | /scripts/form_finding_definition.ghx | Grasshopper file performing structural form finding. |
| .obj | /geometry/generated_form.obj /geometry/laser_scan.obj | Mesh geometries: computational vs. scanned. |
| .mp4 | /videos/printing_sequence_01.mp4 | Video documentation of the printing process. |

------------------------------------------------------------
5. Software Requirements
------------------------------------------------------------
- Rhinoceros 7 or later
- Grasshopper (pre-installed with Rhino)
- Optional plug-ins: Karamba3D, Human
- Any 3D viewer for .obj files (e.g., MeshLab, Rhino, Blender)
- Standard media player for .mp4 files

------------------------------------------------------------
6. Data Usage and Reproduction
------------------------------------------------------------
To reproduce the workflow:
1. Open the .ghx file in Rhino + Grasshopper.
2. Adjust parameters as needed (e.g., boundary conditions, loads, constraints).
3. Export resulting geometries to .obj format.
4. Compare exported .obj to the laser-scanned version using Rhino or CloudCompare.
5. Review the .mp4 files for fabrication details and material behavior.
