Y3 Specialism: Photogrammetry & Procedural Generation

Built a Houdini photogrammetry pipeline that integrates the AliceVision plugin and applied a Diffusion-Limited Aggregation (DLA) algorithm to simulate lichen growth on the captured 3D models based on the paper by Sumners (2001).

Focused on a dual objective:
- Learning photogrammetry, testing workflows with AliceVision and RealityScan.
= Advancing procedural generation methods for organic shapes.
