The original
KIRI Engine
A 3D scanning app that builds models from phone photos, LiDAR and Gaussian splatting.
Replacements
Listings that take over the same core job as KIRI Engine.
Polycam
A 3D scanning app that turns phone captures and drone footage into 3D models and floor plans.
Polycam also scans with a phone on Android, iOS and web, and adds drone footage processing, floor plans, measurements and CAD and BIM export aimed at business teams.
RealityScan
Photogrammetry software from Epic Games that builds detailed 3D models from photos and laser scans.
RealityScan from Epic Games pairs a free mobile capture app with a Windows desktop version that handles photos and laser scans using GPU-accelerated reconstruction.
COLMAP
Photogrammetry pipeline that turns a set of photographs into camera poses and a dense 3D model.
COLMAP is free and open source under BSD-3-Clause and runs on your own Windows, macOS or Linux machine, but reconstruction is slow and needs a capable GPU.
WebODM
Turn aerial photographs into maps and 3D reconstructions.
WebODM is free, open source under AGPL-3.0 and self-hostable, turning aerial photographs into point clouds and textured models, though large image sets need substantial resources.
Similar software
Related functionality, not a direct replacement.
MeshLab
The standard tool for cleaning up messy 3D scan data: fill holes, remove noise, simplify and convert between mesh formats.
Meshroom
Arrange image and 3D processing tasks as connected nodes.
Meshy
A web-based AI generator that turns text prompts or images into textured 3D models.
F3D
A fast, minimalist open-source viewer for 3D models, CAD files, scans and volumetric data.
Manyfold
Self-hosted web app for organising, previewing and sharing a library of 3D print files.
