I would like to create a normal map from a displacement map.
This function is available in 3D applications like Blender, but I would like to do that programatically using VB.NET, however I don't have any knowledge about it.
There was a link to the basic approach here, however it's gone.
Perhaps there is even an imagefilter to do that in .NET.
I'd be glad if anybody with some experience about it could help me here.
