Creates a list consisting of the three dimensional probability distribution cube for turning angle, lift angle and step length (turnLiftStepHist) as well as the uni-dimensional distributions of the differences of the turn angles, lift angles and step lengths with a lag of 1 to maintain minimal level of autocorrelation in each of the terms. Additionally also the distribution of the flight height over the ellipsoid (absolute) and the distribution of flight height over the topography (relative) can be included.

```
get.densities.3d(
turnAngle,
liftAngle,
stepLength,
deltaLift,
deltaTurn,
deltaStep,
gradientAngle = NULL,
heightEllipsoid = NULL,
heightTopo = NULL,
maxBin = 25
)
```

- turnAngle
turn angles of the track (t)

- liftAngle
lift angles of the track (l)

- stepLength
stepLength of the track (d)

- deltaLift
auto differences of the turn angles (diff(t))

- deltaTurn
auto differences of the lift angles (diff(l))

- deltaStep
auto differences of the step length (diff(d))

- gradientAngle
`NULL`

or the gardient angles of the track- heightEllipsoid
flight height over the ellipsoid (absolute) or

`NULL`

to exclude this distribution- heightTopo
flight height over the topography (relative) or

`NULL`

to exclude this distribution- maxBin
numeric scalar, maximum number of bins per dimension of the tld-cube (turnLiftStepHist)

A list containing the tldCube and the autodifferences functions (and additionally the flight height distribution functions)

```
niclas <- track.properties.3d(niclas)[2:nrow(niclas), ]
P <- get.densities.3d(
turnAngle = niclas$t, liftAngle = niclas$l, stepLength = niclas$d,
deltaLift = diff(niclas$t), deltaTurn = diff(niclas$l), deltaStep = diff(niclas$d),
gradientAngle = NULL, heightEllipsoid = NULL, heightTopo = NULL, maxBin = 25
)
