Neurones 3D vs Jawset Postshot

Looking for a Jawset Postshot 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.

Postshot is a Windows desktop application from Jawset that tracks cameras and trains Gaussian splat radiance fields from photos or video on the user’s own NVIDIA GPU, then edits and renders them.

The short answer

Choose Neurones 3D when a splat capture has to become something a surveyor, architect or client can use: a point cloud, a measured section, a classified scene or a floor plan in DXF, all offline and bought once. Choose Postshot when you need to make the splat in the first place: it trains radiance fields from your photos or video on your own GPU and renders them for film and games. The two fit together well: train in Postshot, export PLY or SPZ, and deliver the drawings and measurements in Neurones 3D.

Where Neurones 3D is stronger

  • Takes a finished splat further: converts it to a point cloud, then draws a dimensioned floor plan saved as DXF R2000, SVG and PDF.
  • Measures distances, areas and volumes and cuts 2D sections through the converted cloud.
  • Classifies the converted cloud with trained models (indoor, aerial LiDAR, powerline, streetscape), with a confidence per point.
  • Opens LAS, LAZ and E57 laser scans, so a splat capture can sit beside a scan in one scene.
  • Bought once with no subscription; the free viewer opens splats and runs every process.

Where Jawset Postshot is stronger

  • Postshot trains Gaussian splats from photos and video, with camera tracking; Neurones 3D does not train splats.
  • Postshot renders inside Unreal Engine and After Effects, and the Studio plan handles HDR and images beyond 4K.

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 Jawset Postshot: Creators and visual effects teams who want to train high-quality splats locally from their own footage and render them in Unreal Engine or After Effects.

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.
