Krynth vs OpenMVG

Krynth is a web application that turns photos or video into cloud-rendered 3D scenes and textured meshes, while also processing existing Gaussian splat scans. Its browser viewer opens splat files and creates shareable viewer links. Accepted inputs include.ply,.splat,.spz, and.ksplat files from PostShot, Polycam, Luma, or another pipeline. Listed exports are.ply,.glb, and.obj; FBX is marked as coming soon. Krynth can produce textured mesh output for Unity, Unreal, or Three.js without a local GPU. Users can define camera paths and export MP4 cinematic videos in 4K and ProRes at 30 or 60 fps. Named destinations include Unity, Unreal Engine, Roblox, Blender, Three.js, Apple AR Quick Look, and WebXR. Plans include a free tier, monthly subscriptions, and one-time scans. Paid subscriptions start at $24.00 per month. Scans are private by default and original.ply files can be downloaded for self-hosting.

OpenMVG is an open-source C++ library for multiple-view geometry, 3D computer vision, and structure from motion. It provides libraries, binaries, and pipelines for reconstructing 3D scenes from images. Library areas include image manipulation, feature description and matching, feature tracking, camera models, multiple-view geometry, robust estimation, and structure-from-motion algorithms. Its binaries can initialize scenes, detect and match features, perform reconstruction, and export scenes to other multiple-view-stereo frameworks. Those frameworks can compute dense point clouds or textured meshes from exported scenes. OpenMVG is released under the Mozilla Public License 2.0 and is listed as free. The project says it aims to support reproducible research through readable implementations of classic and state-of-the-art algorithms. It is designed for reading, learning, modification, and use, with test-driven development and samples. Tutorials cover data structures, library use, and processing an image dataset. Platforms listed are Windows, macOS, Linux, iOS, Android, and self-hosted, with desktop deployment, API access, point-cloud export, and ground control point support.
