Wind

The Wind object is typically used to simulate the effect of flowing air for the Airfoil object, to implement sailing boats, gliders, kites, windmills etc.

By adjusting Airfoil object settings you can also simulate other fluid streams, like water (for boat rudder, daggerboard, keel, oars etc).

To enable the effect, simply link the Wind object to Airfoil objects in your project.

The Wind object will also work with Particles and Trail objects.

Multiple instances of the Wind object can be added to your project. This allows you, for example, to configure them differently and enable/disable them run-time by using event objects to achieve changing weather effects.

More sophisticated effects can be achieved by manipulating Wind object's orientation (wind direction) and gushing velocity run-time by using a Script object.



REMARKS

Wind speed and direction can be altered run-time by using event objects and scripts, but the changes may take a few instants to be applied to airfoils, particles and trails.

Setting wind speed too high may cause airfoils linked to RigidBody objects with low mass to apply excessive lift/drag forces to the system, causing inaccurate simulation.

Particles that are emitted before the Wind object is activated (started) will not be affected by wind.

INTERNAL PARAMETERS

The following internal parameters can be accessed by using event objects like EventOnValue or Script:
