@tobiassolem One day you will be the lost duck, but maybe you realise that being lost giving you endless oppurturnities in wich direction you will go ;)
@andrewpprice If RGB values = (0.7, 0.3, 0.8)
Normal Vectors in open gl would be 0.7×2-1= 0.4 [red channel] x axis
0.3x2-1=-0.4[green channel] y axis
0.8x2-1=0.6[blue channel] z axis
For direct x the green channel formula is 1.0-0.3= 0.7
0.7x2-1=0.4 wich is an exact symmetry y axis
