AutoUV shaders [updated: 05/13/2020]

dgud had asked me to try to use 3d position instead of the auv coordinate to calc the shader, so I tried it in Voronoi and I got impressed with effect we can get using the 3D shaders - a seamless texture.
We need to use this kind of shader with a model unwrapped using "segment by projection" -> "Continue projection Normal". Just a sample:

Still not updated because I have more to work.
