🏈 Gaussian Splatting Football Demo

A Unity-based visualizer showcasing how a real football can be scanned, splatted, and thrown in XR using Gaussian Splatting techniques.
This demo is focused specifically on sports object capture for immersive football training and interaction.

🎥 Workflow Overview

1. 📸 Scan Football at 4K 30FPS
   A small autographed football is filmed using 4K 30FPS video for high-detail capture.

2. 🧊 Import Scan into Postshot
   The footage is processed in Postshot to generate Gaussian Splat point cloud data with preserved surface texture and depth.

3. 🧼 Cleanup & Export PLY
   Unnecessary splat noise is removed and the football model is cleaned up for export. Final output is in .PLY format.

4. 🎮 Import PLY into Unity3D
   The splat point cloud is loaded into Unity with PLY parsing and rendered using a custom Gaussian shader.

5. 🤲 Add Physics & Interactions
   XR Grab Interactable and Rigidbody physics are added. Players can grab the football with controller grip input and throw it.
