"Vortex" creates a force field around the daemon's centre and along its vertical axis. Both forces can be adjusted independently. The closer the particles are to the axis, the faster the rotational motion will be.
Affect
"Force" accelerates the particles and they become faster and faster as long as the force is acting on them. “Velocity” affects the particles from the very beginning without any delay or acceleration, but the peak velocity remains constant.
Rot Strength
This is the strength of the rotational force around the daemon’s centre axis. “Rot Strength” accepts positive (clockwise) and negative (counter-clockwise) values.
Central Strength
The centre axis can create an attraction (positive) or repulsion (negative) force.
Attenuation
You can choose from three fall-off types: “Linear”, “Squared” and “Cubic”. The fastest attenuation is achieved with “Cubic”.
Bounded
With “Yes” the "Vortex" daemon is displayed with a stack of three rings around the axis. The radius ("Boundary") of these rings determines the zone of influence.
Boundary
Here the radius of the zone of influence is adjusted.
Vortex Type
“Classic” creates a homogeneous force field, where the fall-off obeys the adjusted “Attenuation”. With “Complex” the forces reach their peak strength at a given distance (= “Radius”) from the centre. This distance is displayed as a dashed circle line around the centre.
Radius
To use this setting,”Vortex Type” must be set to “Complex”. “Radius” determines the distance from the vortex centre in metres where the forces reach their maximum.
Bound Sup
This is the upper limit of the vortex.
Bound Inf
This is the lower limit of the vortex.
