Detailed Description
Linear value interpolator.The interpolator creates intermediate points given a starting and and end point and time constraints. Times are supplied in a discrete unit like miliseconds or microseconds. The values are interpolated on a straight line between the starting and the end point.
The calculation is executed with the following equation:
![\[ \frac{t_\mathrm{current}}{t_\mathrm{end}} \cdot (v_\mathrm{end} - v_\mathrm{start}) + v_\mathrm{start} \]](form_2.png)

Interpolate a point at a specific time.
- Parameters:
-
t_current current time for which to calculate the intermediate point t_end end time/total time. The start time is always 0. t_step Time of a time slice for discrete intermediate interpolation points. Set to 1 for maximum resolution. v_start start value v_end end value
- Returns:
- interpolated value at time t_current between t_start and t_end.
