This HUD graphically displays the wind direction and speed. It also shows the orientation and speed of the vehicle you are in.
This HUD has been designed to be used in sailboats that normally cannot advance correctly if the wind comes from the bow, that is to say they have the windward against.
However, it can be used with any type of vehicle if the wind is important in some way. Hot air balloons?
There are several ways to measure the wind in secondlife using the function llWind(). This HUD takes the cube root of the wind speed at position <0, 0, 0> and multiplies it by five.
Some vehicles may change the way they do it and return different results.
I have decided to sell the HUD with all the permits so that it can be easily modified and adapted to specific needs.
This is not to be resold, unless you use it as part of your own build. For example, a HUD with more functionalities or if you manage to make the necessary modifications to the script in such a way that you can link it to the panel of a vehicle.
