📸

Scan the Unscannable

Go beyond basic photogrammetry. Use Neural Surface Reconstruction (NSR) to capture shiny, reflective, or featureless objects that other scanners simply can't handle.

🛠️

Production-Ready Exports

Streamline your workflow with auto quad-mesh retopology and AI-generated PBR materials. Export directly to Blender, Unreal Engine, or Unity in OBJ, STL, and FBX.

✨

Next-Gen Spatial Capture

Harness 3D Gaussian Splatting to turn simple videos into immersive 3D scenes. Capture complex environments with realistic reflections and cinematic detail instantly.

"I used to spend hours trying to manually model replacement parts for my 3D printer, but KIRI Engine changed everything. I scanned a custom vintage handle, exported the STL, and had a perfect replacement printing in under an hour. The level of detail you get without needing an expensive dedicated scanner is absolutely insane!"

Mark R., Maker & 3D Printing Hobbyist

"KIRI Engine has become an essential part of my environment design workflow. The Featureless Object Scan is a lifesaver for capturing those tricky reflective surfaces that usually fail in photogrammetry. Being able to export clean quad-meshes directly into Blender has cut my asset creation time in half. It is a professional-grade tool right in my pocket."

FAQ

Frequently Asked Questions

Everything you need to know about KIRI Engine:3D Scanner & LiDAR

What is KIRI Engine and what does it do?

KIRI Engine is a 3D scanner app that creates high-quality 3D models from photos or videos using photogrammetry, Neural Surface Reconstruction (NSR), and 3D Gaussian Splatting technologies. It supports editing, refinement, and various export formats.

How does KIRI Engine create 3D models?

KIRI Engine utilizes photogrammetry to convert photos into 3D models. It also offers Neural Surface Reconstruction (NSR) for featureless objects from video and 3D Gaussian Splatting for full 3D visualizations, including reflections, from video.

Can KIRI Engine scan shiny or featureless objects?

Yes, KIRI Engine's Neural Surface Reconstruction (NSR) feature processes video scans to effectively capture featureless or shiny objects. This technology is integrated into the Featureless Object Scan capability.

Is KIRI Engine free to use?

Yes, KIRI Engine provides a functional free version. This includes unlimited 3D scans and at least three exports per week without requiring subscriptions, LiDAR sensors, or expensive 3D scanners.

What 3D model export formats does KIRI Engine support?

KIRI Engine supports exporting 3D models in OBJ, STL, FBX, GLTF, GLB, USDZ, PLY, and XYZ formats. These formats ensure compatibility with software like Blender 3D, Unreal Engine, and Autodesk Maya.

Does KIRI Engine require a LiDAR sensor?

No, KIRI Engine does not require a LiDAR sensor for its primary functions; its algorithms provide comparable scanning quality. However, the app supports on-device photogrammetry and 3D room plans on LiDAR-equipped iPhones.

What features are included in KIRI Engine Pro?

KIRI Engine Pro offers features like camera roll uploads, quad-mesh retopology, AI PBR material generation, an advanced camera system, enhanced Featureless Object Scan, 3D Gaussian Splatting editing, and WEB version access.

Can KIRI Engine edit 3D models directly in the app?

Yes, KIRI Engine provides in-app editing tools to refine 3D models, allowing adjustments, precise photo selection, Auto Object Masking for cleanup, and model preview using a 3D viewer and augmented reality panels.

What is Auto Object Masking in KIRI Engine?

Auto Object Masking in KIRI Engine ensures noise-free and clean 3D models by automatically eliminating background elements during capture. This feature also allows objects to be moved while scanning.

What texture resolution options does KIRI Engine offer?

Yes, KIRI Engine allows exporting textures up to 8K resolution. Users can select from 1K, 2K, 4K, and 8K options for detailed texture output, especially with PBR materials.
