I'm ready to open up the app for community testing. If you want to try it out and help me refine the SfS logic "in the wild," you can join the beta starting today.

I ve been working on a project called Nack, and I wanted to share it with fellow creators who are struggling with low-quality texture generation.
The Problem: Most modern mobile scanners and generators rely on AI. While it looks cool at first glance, it often "hallucinates" details, creating blurry normal maps and physically incorrect geometry.
The Solution: I decided to go back to the roots. Nack uses a deterministic Shape from Shading (SfS) algorithm. No AI, no cloud servers, 100% offline. It extracts high-frequency details (pores, fabric weaves, stone grains) from a single smartphone photo in just 4-10 seconds.
Stop overpaying for LiDAR. Nack uses advanced Computer Vision to extract high-fidelity 16-bit depth and normal maps from a single flash photo. While photogrammetry needs 50+ images, Nack’s SfS-algorithm reconstructs micro-surface geometry instantly.
Key Features: • 16-bit PNG: Pro-grade HDR data for ZBrush/Blender. • PBR Ready: Instant Normal maps for Unity/Unreal. • No Hardware Limits: Works on any Android. • Sub-millimeter detail: Captures textures LiDAR misses.
Perfect for 3D artists & QC.
