Pulga Vortex Force

Functionality

This node creates a force to be applied with the Pulga Physics Solver node. The vortex force is defined with a “Line” with Location and Direction. It has three components, rotation around the line, attraction towards the line (Inflow) and a movement in the line direction (Forward).

Input

Location: A point of the line.

Direction: Direction of the line.

Rotation Strength: Multiplier of the rotation force.

Inflow Strength: Multiplier of the inflow force (towards the line).

Forward Strength: Multiplier of the forward force (in the direction of the line).

Max. Distance: Distance under the force will be applied.

Decay: How the force will decay with distance. 0= no decay, 1= linear, 2= cubic, 4= quadratic…
