KIRI Engine

The reason KIRI Engine shows up in scan-app shortlists is that it covers four capture methods in one mobile app. Photo Scan handles ordinary photogrammetry. LiDAR Scan on LiDAR-equipped iOS gear covers room scans, scene scans, and object capture. Featureless Object Scan is a NeRF-derived route for shiny, reflective, transparent, or single-color objects that classic photogrammetry cannot reconstruct. And 3D Gaussian Splatting gives you high-fidelity real-time visualizations that export with a mesh attached so the asset still works in other 3D software. The post-processing toolchain is where it separates from thin capture apps. AI-generated PBR materials come out as separate albedo, roughness, normal, and displacement maps. Quad-mesh retopology lets you pick poly count and curve ratio, with dynamic decimation on top. Auto-rigging generates a skeleton for animation and motion capture. High-poly output reaches million-level vertices with textures up to 8K, and STL export covers 3D printing specifically rather than making you convert. On the free tier: unlimited scans, unlimited free exports, no ads, no watermarks, up to 150 photos and 2 GB per scan. That's a genuinely usable plan rather than a demo. Pro raises the per-scan limits to 500 photos and 5 GB, adds faster queuing and processing, and unlocks Featureless Object Scan, mesh-inclusive 3DGS, PBR materials, quad mesh, and auto-rig. Pricing is $17.99/month, or $79.99/year — the yearly plan works out to about $6.66/month billed annually, so the monthly option costs roughly 2.7x more per month if you only need a short burst of work. Where it does not fit: sub-millimeter measurement work belongs on desktop photogrammetry like RealityCapture. Heavy occlusion, fine hair, and fur remain hard problems for photogrammetry generally. Processing is cloud-based, so you need a connection. And there is no desktop application — the workflow is phone plus web browser, which is a strength for portability and a constraint if your pipeline lives on a workstation.
