Hi Green Gandalf,
To cut a long story short, im trying ot make an app that will generate a normal map from any given image.
So far i can load and image, process it as a normal map and then slightly blur the image to get rid of som of the roughness.
I think what needs to happen is load the image, remove noise, then generate the normal map.
When i compare my generated normal maps to that of Cray bump for example, there is a big difference in the amount of finer detail.
So i guess my question really applys to any image.
Any help is greatly appreciated.
