ForcePhysicsModel applies a constant force value to the particles.
The ForcePhysicsModel 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] force 0 -9.8 0 (∞,∞)
Force field indicates strength and direction of the propelling force on the particles (e.g. default is Earth's gravity).
Force is specified in force base units (usually newtons). If particles have zero mass, ForcePhysicsModel node has no effect.
