Tangent Space Normals Utilities v1.1

TANGENT SPACE NORMALS UTILITIES 1.1

colour-science.org - April 9, 2015

The attached file is a playground for implementation of various tangent space normals utilities. They are available as groups and can be copy / pasted quickly from the file to another or alternatively installed as gizmos.

• Normalise_Tangent_Space_Normals: Normalises tangent space normals.Partial Derivative Blending: Blends tangent space normals together using Partial Derivative Blending.
• Tangent Space Normals Generator: Generates tangent space normals from given input.
• Multi Tangent Space Normals Generator: Generates tangent space normals from given input using multiple Tangent Space Normals Generators.
• Brute Force Tangent Space Normals Generator: Generates tangent space normals from given input using brute force method: A card is tesselated and displaced in the 3d space and normals are rendered using Nuke ScanlineRender.
• Tangent Space Normal to Cavity: Performs conversion from Tangent Space Normals to Cavity.
• Tangent Space Normals Previewer: Preview tangent space normals by using angular mapping lighting.

A showcase video is available on Youtube: https://www.youtube.com/watch?v=hklnu-VspSY

Examples with a Nuke noise (Render is done with Marmoset Toolbag 2):
