Modifiers also affect other elements

A "Rotation Object" Modifier affects a Hair Object (HAIR), a number of Splines ( Rope tag), flags (Cloth) and a MoSpline.

Modifiers not only affect particles but these elements as well:

• HAIR: Hair Object Forces field, Rope tag's Forces field.
• Cloth: Forces tab.
• MoGraph: On the MoSpline in the Fields field and Bullet Dynamics in the Rigid Body tag (in the Force List).
• Bullet Dynamics: on Rigid and Soft Bodies

Imagine points instead of particles that are influenced by the modifiers. These points are Guide points (HAIR), Spline points (, Rope tag, MoSpline) or object points (Cloth). Note that not all modifiers can be used effectively outside of a particle system. For example, Deflector and Destructor objects will function only in a limited fashion if at all. However, Wind, Turbulence and Rotation objects will always work.
