Introduction - If you have any usage issues, please Google them yourself
This is a project to use to the " three-dimensional space vector/point" category and related functions, use them to define a space vector/point to achieve the translation vector, scaling and rotation, etc. can also be achieved using the correlation function of two vectors fork multiply, get a vector of the absolute length of a vector unit, get a three-point decision to the vertical plane of the vector (after unit-based), get the distance between two points in space, to be two vector dot product, to be two vector angle and other operations, the use of user-friendly, each function has a detailed comment, hope you all have a use.
