Renaissance-the-movie Shading

From C4 Engine Wiki

Renaissance (the movie), is a (beautiful) French 3D animation movie released in 2006. Its graphical specificity was that the whole movie is in Black and White. Here is a shader that makes your scene look like the movie.

Bump is calculated twice, once from z Tangent View Direction then with Object Normal to get more details. As I didn't substract dot((z-T.V.D.), Object Normal) to result, I get a white silhouette that delimit objects.

Then result is thresolded to get Black and White.

Finally diffuse reflection is applied with the inverted color of the result above. This way normal mapping is applied by the same process.

Don't do anything in the Ambient Pass (connect 0.0 Constant Scalar to the Lighting Output) and connect the final process to the Lighting Output.
