What KIRI Engine is

KIRI Engine is a 3D scanning application that creates models and visualizations using photogrammetry, Neural Surface Reconstruction, and 3D Gaussian Splatting. Photo Scan builds 3D models from photos, while LiDAR Scan supports model scans, floor plans, and quick scene visualizations on LiDAR-equipped iOS devices. Featureless Object Scan is designed for shiny, reflective, transparent, and low-texture objects. The free Basic plan allows up to 150 photos and 2 GB per scan, with unlimited scans and free exports. Pro supports up to 500 photos and 5 GB per scan, faster queue processing, and advanced scanning and modeling features; it costs $17.99 a month or $79.99 a year. The API offers Photo Scan, Featureless Scan, and 3DGS Scan, with each call using one credit. Credits cost 1.00 USD each, with a 500-credit minimum recharge; sign-up includes 10 free test credits. Other listed tools include a website model embedder, UE5 plug-in, and STL export. Uploaded photos and videos are processed on cloud servers.
