Neurones 3D vs Agisoft Metashape

Looking for a Agisoft Metashape alternative? Neurones 3D is free, offline point cloud and Gaussian splatting software for Windows: the free viewer runs every process, from AI classification to dimensioned floor plans, and a one-time paid edition saves the results.

Agisoft Metashape is photogrammetry software that builds point clouds, DEMs, orthomosaics and textured 3D models from aerial, close-range and satellite imagery. The Professional Edition adds LiDAR and laser scan support, point classification and Python and Java APIs.

The short answer

Choose Neurones 3D if your input is already a point cloud and you want ready-trained classifiers, M3C2 change detection, terrain, contours and dimensioned plans in an offline Windows application, with a free viewer that runs every process. Choose Agisoft Metashape if you create 3D data from photographs, from drone survey to heritage, and want a mature photogrammetry pipeline on Windows, macOS or Linux with a licence that is not time-limited and Python and Java APIs.

Where Neurones 3D is stronger

  • M3C2 change detection with a 95 % level of detection, plus cloud-to-cloud and cloud-to-BIM deviation; Metashape documents a difference view mode for laser scans.
  • Four scene-specific classifiers (indoor, aerial LiDAR, powerline, streetscape) ship trained, with a confidence per point; Metashape’s classifier training arrives in a 2.4.0 preview.
  • A free viewer that opens, views and runs every process; Metashape’s trial licence lasts 30 days.

Where Agisoft Metashape is stronger

  • Photogrammetry from aerial, close-range and satellite imagery, with orthomosaics, tiled city models and 4D; N3D does not process photos.
  • Runs on Windows, macOS and Linux, with network processing across several computers.
  • Registers terrestrial laser scans together with photos, and detects powerlines from images alone.

Who should choose which

Choose Neurones 3D to take a point cloud or a splat capture to a finished deliverable on your own machine: classified LAS, a dimensioned floor plan with sections and elevations in DXF, a DTM with contours, a change map or a report, without an account, an upload or a subscription. Every figure it publishes is measured; see the benchmarks.

Choose Agisoft Metashape: Photogrammetry users, from drone survey to heritage and VFX, who need a proven image-to-3D pipeline with a licence that does not expire.

About

Why Neurones 3D exists.

Standing inside a 43.5 million point indoor laser scan rendered by Neurones 3D

I have spent years working with point clouds, and for most of them the software got in the way. I wanted one tool I would actually reach for every day: fast enough to enjoy, honest about what it does, and calm to use.

Neurones 3D started in Python, the way most of my research does. It worked, but it was heavy, and heavy tools quietly discourage you from opening them. So I rebuilt everything in Rust, from the file readers to the renderer, with one rule: stay frugal. A single small file, no cloud, no telemetry, billions of points on a laptop that is ten years old. In an age where every tool reaches for a data center, I wanted the opposite.

The goal is simple to say and hard to earn. One package that carries you from capture to understanding to deliverable, without exporting to five other programs along the way. Load a scan, a splat, a building, a phone video. See it, classify it, measure it, and send out something real. Together, in one place.

This is the tool I always wanted. I hope it becomes yours too.
