If synthetic velocity is set to V, the velocity of each axes Vn should
be:
See figure below for a two dimension straight line interpolation
with starting point at S and ending point at E:

ΔX and ΔY is the offset at X-axis and Y-axis respectively.
Interpolation distance is set according to component of each axis
(e.g. relative distance ΔX and ΔY or absolute coordinates of
ending point E). The composite shift ΔP can be calculated by
formula described below:
Velocity and acceleration are set by composite vectors.
Component of each axis, take composite velocity Vx and Vy as
example, can be calculated by formula described below:
