TYPE: POP
TITLE: Torque POP

The Torque POP applies a rotational force to the particles.  To help
visualize the effect of this operator, turn on the particle axes flag
in the view display options. The torque is expressed as a force applied
to a position relative to the particle.

This POP modifies the following attributes: torque.

Parameters:
    Activation       - Turns the POP on and off		/activate
    Source Group     - Subset of points to act on
Torque
    Force         - Force magnitude 			/forcex /forcey /forcez
    Position      - Position at which to apply force	/posx /posy /posz
    Scale         - Overall force scaling factor	/scale
    Ignore Mass   - Ignore particle mass 
    Override Mass - Override particle mass
    Mass          - Mass to use for override		/mass
Noise
    Seed       - Seed for random turbulence generator 		/seed
    Turbulence - # of iterations to add fractional noise	/turb
    Roughness  - Scale of noise added with each iteration	/rough
    Exponent   - Noise attenuation				/atten
    Frequency  - Spatial frequency of noise field	/freqx /freqy /freqz
    Amplitude  - Maximum value of noise field		/ampx /ampy /ampz
    Offset     - Amount to shift noise		/offsetx /offsety /offsetz
    Noise Type - Noise type to generate	

Local Variables 
    Overview - The standard local variables are usable in this POP.  Please
               refer to the Houdini manual for more details.
