Chrysoprase Specimen (chry-001) — Gaussian Splat

Green crystal specimen (identified in notes as Prehnite from Bagdad, AZ) captured and reconstructed using Gaussian Splatting.

Specimen Details

• Mineral: Prehnite (green crystal)
• Location: Bagdad, AZ
• Listed on: Borussia Minerals

Capture Method

• Device: iPhone (handheld)
• Total frames captured: 24 (green-crystal-cropped session)
• Accepted frames: 16 (images/ directory)
• Rejected frames: 8 (rejected/ directory — kept for reproducibility)
• Coverage note: Light coverage — only 24 frames total, limited top/bottom angles

PLY Iterations

Run	Iterations	Node	Size	Notes
v1-macbook-7k	7,000	MacBook Pro	133MB	First successful run

Training Pipeline

1. Structure from Motion: COLMAP (feature extraction + matching + mapping)
2. Gaussian Splat training: opensplat
3. Input: Background removed / cropped source images

Known Issues

• Only 24 source frames — coverage gaps at top and bottom angles
• A reshoot with more frames would improve reconstruction quality
• Single PLY iteration available
