3DF Zephyr vs Nerfstudio

3DF Zephyr is Windows desktop software that reconstructs 3D models from photos, with workflows involving camera sensors, drones, and laser scanners. It estimates camera parameters automatically and offers global or incremental reconstruction pipelines. Outputs include orthophotos, orthomosaics, DEMs, contour lines, sections, CAD drawings, measurements, and project reports. Users can upload models to Sketchfab and videos to YouTube; Unity ArtEngine integration is described for people with an ArtEngine license. Plugins include native support for several laser scanner formats, a beta Canon DSLR remote-shooting plugin, and an experimental GEOBIM Revit plugin. Python scripts and XML files can automate workflows and batch processing. The free plan is for personal use and allows 50 photos or video frames, with limited exports and editing. Zephyr requires Windows 10 or 11, at least 16 GB of RAM, and 20 GB of free disk space. The listed Lite plan costs €199 a month, while the full Zephyr plan is listed at €4,200 a month.

Nerfstudio is a free, open-source API and toolkit for creating, training, and testing Neural Radiance Fields through modular components. Included methods are Nerfacto, Instant-NGP, NeRF, Mip-NeRF, TensoRF, and Splatfacto, its Gaussian Splatting implementation. Command-line tools process data, train and evaluate models, render videos, view trained scenes, and export models. A web viewer shows training in real time, lets users interact with scenes, renders custom camera trajectories, and creates videos. Share URLs allow others to watch progress, but those links are publicly accessible and can add latency. Documented capture workflows use COLMAP, Polycam, or Record3D to turn phone video into a 3D render. Installation is available through pip, source, or Docker. Docker requires NVIDIA GPU drivers supporting CUDA 11.8, and the quickstart requires an NVIDIA video card with CUDA installed. The project supports Tensorboard and Wandb logging, profiling, and debugging. It runs across Linux, Windows, web, API, and self-hosted environments, with Windows described as less tested and more fragile.
