Represents a 3D path, created from the interpolation of a sequence of GeoPathSample values.
After creation, a geo path is empty. Path samples must be added to it, in order to form a 3D path. The timestamps of samples can be distributed arbitrarily (i.e. there is no requirement for a fixed time-step). The geo path can be used to translate between sample indices and timestamp values.
Smooth interpolation is performed with non-uniform B-splines, where control points are implicitly duplicated before the first and after the last sample. For a given timestamp value
T, the influencing geo path samples look like this:
t1 t2 t3 t4 t5 t6 control point timestamp |------|--|----x---|----|---------| 1 2 3 | 4 5 6 control point index T interpolation timestamp
Geo path samples are interpolated from the values of control points [2..5].
Interpolation factors are computed from the timestamps of control points [1..6].
Creates a new instance of GeoPath.
Performs ground adjustment for a single geo path sample.
