SmartNormal is a AIR-standalone that loads pictures up to 2880px that are first processed with a condensed or sobel edge-detection algorithm and then normalised.

The created normalmap can be saved as JPEG and used with any 3D-engine or program that supports normalmapping.

SmartNormal is freeware.

Update: SmartNormal can now also be used directly in-browser (Flash10) and uses a PB shader for realtime filtering.
