Matthew Brennan is not a computer scientist, but he takes 335 frames from a video and then processes them 3 different ways to compare the results. He creates a 3D mesh out of it for Photogrammetry, the processes it into a NeRF, and finally Gaussian Splatting.

What’s cool is that he shows how each works and how to process the data yourself. He also gives you access to the data to try it yourself.

Here’s the software he uses:

• Photogrammetry model on sketchfab: https://skfb.ly/oLOQw
• Church Rock dataset ZIP: https://drive.google.com/file/d/1ttkl…
• Agisoft Metashape: https://www.agisoft.com/
• NerfStudio: https://docs.nerf.studio/
• 3D Gaussian Splatting for Real-Time Radiance Field Rendering: https://github.com/graphdeco-inria/ga…
• Aras-p’s Unity Project: https://github.com/aras-p/UnityGaussi…
