this is a patch for a node that does normal maps from any image.
It also does refraction according to Snell’s law and outputs values for the displace node to create a refraction effect
on the image.
The input image is used as a glass through which the second image is viewed.
Looks like we now have a good normal map node in Blender, and the other one is a nice bonus. With the Toronto Design project well underway we’re seeing our node system starting to get a big boost.
Looks like the screens shown is for compositing stuff but hopefully we see the normal map node in the material nodes as well.
EDIT: And here’s another node goodie, the threshold node
