WindPhysicsModel applies a wind effect to the particles. The wind includes a random variation factor to model gustiness.
The WindPhysicsModel node belongs to the ParticleSystems component and its container field is physics. It is available since X3D version 3.2 or later.
SFNode [in, out] metadata NULL [X3DMetadataObject]
Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.
SFBool [in, out] enabled TRUE
Enables/disables node operation.
SFVec3f [in, out] direction 0 0 0 (∞,∞)
Direction in which wind is travelling in the form of a normalized, unit vector.
SFFloat [in, out] speed 0.1 [0,∞)
Initial linear speed (default is m/s) imparted to all particles along their direction of movement.
SFFloat [in, out] gustiness 0.1 [0,∞)
Gustiness specifies how much wind speed varies from the average speed.
Wind speed variation is calculated once per frame and applied equally to all particles.
SFFloat [in, out] turbulence [0,1]
Turbulence field specifies how much the wind acts directly in line with the direction, and how much variation is applied in directions other than the wind direction.
This is determined per-particle to model how each is effected by turbulence.
