computeVvlhTransform
external fun computeVvlhTransform(time: JulianDate, positionProperty: PositionProperty, result: Matrix4): Matrix4(source)
Compute the vehicle velocity, local horizontal (VVLH) transform for a position property at a given time. The VVLH axes is defined based on the motion of the provided position point as follows:
The X axis is directed toward the point's velocity vector, in the direction of motion.
The Y axis is along the angular momentum vector.
The Z axis is along the position vector.
Return
The VVLH transform.
Parameters
time
The time at which to compute the VVLH transform.
positionProperty
The position to compute the VVLH frame for.
result
The object onto which to store the result.
