VCG - Tumble Vortex

Description

Generates a Tumble Vortex in the middle of the x-y-plane with parametrizable z component up to quadratic order.

Details

This plugin generates a Tumble Vortex along the z axis with parametrizable z velocity component. The angular velocity of the rotation can be specified. Also the z velocity component can be defined up to quadratic order using the three parameters in the GUI encoding first the quadratic, then the linar and then the constant factor.

Input

null

Output

vtkDoubleArray
