A full breakdown of each tool and tutorials are available here: http://erwanleroy.com/vector-tools-for-nuke-tutorials-and-math/
Luma_to_Normals: Converts any image to normals, using it's Luma Channel. Provides most accurate results used on displacement maps or Zdepth passes.
UV_Map_Generator: Generates a default UV map at any resolution. Can be used to run through a lens distortion in another software or any sort of distorion that can then be re-applied with an STMap node.
UV_MAP_Layer: Similar to UV_Map_Generator, but adds the UV map in a layer to an input image.
UV_to_Vectors: Converts a distorted UV map to motion vectors.
Vectors_to_UV: Converts Motion Vectors to an UV map.
VectorTransform: Like Nuke's default transform, but will rotate vectors and scale them accordingly.
vector3DMathExpression: A NoOp node with expressions to calculate a 3D vector between 2 3D points, as well as it's magnitude.
Vectors_Direction: An utility to rotate 2D vectors such as motion vectors, and flip them if necessary.
Vectors_Magnitude: An utility to see the magnitude of motion vectors, usually simply as information for the artist.
Vectors_Normalize: Will scale every vector in a vector pass so that each vctor's magnitude is 1, while keeping the direction. Works on 2D and 3D vectors.
Vector_to_Degrees: Gives you an angle value (0-360) for a given channel. Can be used to generate Anisotropy maps from vectors for CG.
-Fixed Vectors_Normalize to normalize every vector, not only the ones too long.
