Deformed Arrows in a 3D scene due to height

I am using a polyline with the 4 nodes to represent a 3D wind arrow over the terrain using relative height. This approach however makes some arrows to be deformed since the absolute height of each node depends on the surface height (see image attached). I do not use absolute height because I do not know the height of the terrain and I need the arrows to be very close to the surface.  Any advice of how I could solve this??? is there any way to convert an relative height into an absolute one??, any fast way of knowing the height of the terrain at a given point?


Thanks in advance


PD: I have this problem in .Net and in Qml with AppStudio.
