This guide explains how each one fits, what pipeline they run under the hood, and what to do with the output point cloud once it lands on your disk.

Photogrammetry in 30 seconds

Photogrammetry, as defined by Wikipedia, is the science of obtaining reliable information about physical objects through the recording, measuring and interpreting of photographic images. Concretely: you take a lot of overlapping photos around an object, a facade or a site, you feed them into a software, and the software reconstructs a 3D scene with measurable coordinates.

The dominant algorithm today is Structure from Motion (SfM): the software detects features in each photo (corners, edges), matches them across images, filters bad matches with RANSAC, and infers both the 3D position of points and the camera trajectory. The output is, in 95% of cases, a 3D point cloud, often followed by a textured mesh, an orthophoto and a digital surface model.

If you want a deeper primer on what a point cloud actually is, read our piece What Is a Point Cloud first, it covers formats (E57, LAS, LAZ, RCS, RCP, LGSx) and what professionals do with the data downstream.

Selection criteria that actually matter

Before benchmarking individual tools, write down what you need. Seven criteria recur across every serious procurement we have seen:

• Type of capture: terrestrial photos, drone aerial, mixed with LiDAR or none of that.
• Project scale: object of 30 photos, building of 800 photos, or open-pit mine of 5000 photos.
• Processing location: local workstation with a beefy GPU, render farm, or cloud SaaS.
• Output formats needed downstream: OBJ, FBX, PLY for VFX; E57, LAS, LAZ for AEC and surveying; RCP, RCS for Autodesk pipelines; orthophoto + DSM for mapping.
• Licensing model: perpetual, annual subscription, free tier under a revenue threshold, fully open source.
• Team workflow: solo expert, small studio, multi-site enterprise with a CDE.
• Compatibility with the rest of your stack: BIM (Revit, ArchiCAD, AllPlan), GIS (QGIS, ArcGIS), 3D visualization platforms.

Free, open source or paid: which one is right for you?

The free-versus-paid debate is less binary than it looks. Three different free paths exist in 2026, and each implies a different cost model.

What happens after the photogrammetry software

Once Metashape, RealityScan, Pix4D or Meshroom finishes processing, you are left with a point cloud file: most often E57, LAS, LAZ, RCS or RCP. From here the engineering workflow really begins.

You need to review the data, share it with stakeholders, compare it to a designed BIM model (scan vs BIM, called "as-built"), extract slices, place sections, write annotations. That work rarely happens inside the photogrammetry tool itself, because those tools are optimized for reconstruction, not for review and collaboration.

This is where ATIS.cloud comes in. ATIS.cloud is a 3D app and collaboration platform dedicated to point cloud review. It is agnostic on the capture side and reads the output of every photogrammetry tool listed above.

• Reads E57, LAS, LAZ on all plans (standard open formats).
• Reads RCS, RCP, LGSx on all plans (Autodesk and Leica Hexagon proprietary).
• Browser-based: your BIM manager opens the scene without installing anything.
• Also reads LiDAR static and mobile scanners from every scanner brand (FARO, Leica, NavVis, Riegl, Trimble, Viametris, Matterport, etc.).
• One single review interface covers both photogrammetry and LiDAR jobs.

Honest limits of photogrammetry

Photogrammetry is not a silver bullet. Three known weaknesses keep surveyors and BIM teams cautious.

• Low-texture surfaces (white walls, glass, polished metal, water) confuse feature detection and produce holes in the cloud.
• Lighting variation between shots disturbs matching: cloudy days are usually friendlier than harsh sunlight, and indoor scenes need consistent artificial lighting.
• Vertical (Z) accuracy is generally lower than terrestrial LiDAR, which is why many serious surveying jobs combine the two technologies.

Where ATIS.cloud fits in your photogrammetry stack

Let's be honest about what ATIS.cloud does and does not do. ATIS.cloud is not a photogrammetry engine: it does not reconstruct a 3D scene from photos. It is the next step in the pipeline: a 3D app that reads the point cloud produced by Metashape, RealityScan, Pix4D, Zephyr, Meshroom or OpenDroneMap, and turns it into a shareable, reviewable, comparable asset for your team and your clients.

• Browser-based review: open files up to 1 TB (5 TB of total workspace) without installing anything heavy.
• Sovereign hosting in 22+ countries, your data stays where you need it.
• Sharing with internal and external collaborators, with role and access control, plus AES 256-bit encryption.
• Scan vs BIM (called "as-built") comparison against IFC models for Advance plans, plus BCF export.
• Compatible with all the scanner brands listed above, so the same review interface covers both photogrammetry and LiDAR jobs.

If you want to see the workflow end to end, the article What Is Scan to BIM shows how to go from a raw point cloud (photogrammetry or LiDAR) to a comparison against an IFC model. The complementary piece Compare Point Clouds and 3D Models gives the conceptual map.

Choosing in 2026: a five-step decision guide

1. Define the typical capture: terrestrial photos (Metashape, Zephyr, Meshroom) or drone aerial (Pix4D, DroneDeploy, ODM, RealityScan).
2. Pick a processing location: local GPU (all desktop tools), distributed cloud (DroneDeploy, Pix4Dcloud, in-house WebODM).
3. Pick a licensing model: perpetual (Metashape, Zephyr), subscription (Pix4D, RealityScan above threshold), open source (Meshroom, ODM), revenue-based free (RealityScan below 1M USD).
4. Validate output format compatibility with your downstream tools: E57 for AEC review, LAS / LAZ for surveying, OBJ / FBX for VFX, RCP / RCS for Autodesk pipelines.
5. Pick a downstream review platform: ATIS.cloud is one option, designed specifically for collaborative review and BIM comparison on the point cloud you just produced.
