Full Photogrammetry Guide for 3D Artists
Vlad Kuzmin's extensive guide for efficient photogrammetry captures, hosted by 80.lv.
Unity Photogrammetry Workflow
Sébastien Lachambre, Sébastien Lagarde, Cyril Jover
This document aims to describe a photogrammetry workflow dedicated to authoring game assets with an affordable budget for a game studio. It goes through image capturing, image processing, point cloud and mesh reconstruction, model clean-up, reduction and retopology, texture transfering, and post-processing.
