Description
TVector is a vector in a two-dimensional space.
TVector is a record that represents a vector in a two-dimensional space. The vector has its initial point in (0, 0). X and Y are the coordinates of the terminal point of the vector. To be able to realize a vector transformation, using a transformation matrix, the coordinates number is extended to three. So, W represents a coordinate that will help in vector transformation.
