3DUnderstanding 3DGS, Part 2: How Is 3DGS Different from Photogrammetry?
3DGS and photogrammetry both reconstruct 3D scenes from multiple photos and share key SfM steps. This article explains where they diverge: photogrammetry continues to MVS, dense point clouds, meshes, and textures, while 3DGS optimizes Gaussians to reproduce photorealistic views.
3DUnderstanding 3DGS, Part 0: How Do Photos Become 3D? — 170 Years of Trial and Error
How did photos become 3D? This article traces the evolution from 19th-century photogrammetry and stereo vision to SfM, MVS, NeRF, 3D Gaussian Splatting, and 2DGS, explaining how photography evolved from a recording medium into a tool for reconstructing and revisiting real-world spaces.
3DLost in the Majestic Underground: When the Entire World of Caves Fits Within Your Sight
Cave Explorer turns real cave scans into an interactive web experience using point clouds, 3D Tiles, LOD, and real-time rendering. This article explains the data pipeline, browser performance challenges, remote exploration, digital heritage use cases, and future features.
