Tangent Normal Map Brush Engine for Krita

by Wolthera for KDE

Experimental Tangent Normal Map Brush Engine for Krita. A surface normal is a type of vector used to determine how light bounces off a surface. 3d graphics have has a way to encode these in normal-maps. To the human eye, this encoding looks like a colour. This brush engine takes the tilt sensors of a tablet stylus, and treats it like a surface normal, having it output the correct colour. I think this would be a worthwhile asset to Krita because of the interest in hand-painted textures.
