Capturing real-world objects and environments by photographing them from hundreds of angles and reconstructing them as 3D models.
Photogrammetry works by taking hundreds or thousands of photographs of a subject from different angles, then using software to match common points between images and reconstruct a 3D mesh with texture data. The resulting models carry the imperfections, weathering, and micro-detail of the real world that even the most skilled 3D artist would struggle to replicate manually. Rocks have natural erosion patterns, tree bark has organic irregularity, and building facades carry decades of wear. The technique has become a cornerstone of AAA game art production, though it comes with challenges: consistent lighting during capture, massive raw data sizes, and the need to clean up and optimize scanned meshes for real-time use.
Example
Star Wars Battlefront (2015) by DICE pioneered photogrammetry in AAA games, scanning actual Star Wars props and filming locations to create environments of staggering authenticity. The Decima engine used in Horizon Forbidden West and Death Stranding employs photogrammetry for rocks, foliage, and terrain that look naturally weathered and organic. Microsoft Flight Simulator uses satellite and aerial photogrammetry to reconstruct entire cities in 3D, giving you a flyable model of the actual planet.
Why it matters
Photogrammetry has raised the baseline for environmental realism in games. Once you have seen photogrammetry-quality rocks and surfaces, hand-sculpted alternatives can look artificially clean. It also dramatically accelerates asset creation for environments, since scanning a real boulder takes minutes compared to hours of manual modeling. The technique represents a bridge between the real and virtual worlds that grows more important as games chase photorealism.
