I've always found it a bit overkill to open heavy software just to generate a quick normal map. Most online tools either have clunky UIs or upload your files to their backend.
I built this using Three.js and client-side canvas processing (Sobel/Scharr filters). Everything happens locally on your machine, so it's fast and private.
Features:
- Generate Normal, Displacement, AO, and Specular maps.
- Real-time 3D PBR preview with shape selection (Plane, Cube, Sphere).
- Fine-grained control over strength, blur, and axis inversion.
Would love to get some technical feedback on the processing performance!
