A simplied depiction of the arrangement of dynamics springs.
Imagine this arrangement of springs attached to each guide (all springs simultaneously serve to push or pull), which ensures that the
guides do not simply collapse when a force is applied. The guide pictured above consists of three segments. The arrangement of springs
also functions the same with guides containing more segments.
The following springs are not pictured:
 The spring that holds the root segment in place (this spring is attached to the rst guide kink and pulls the
root segment back to its rest state if moved. This spring can be adjusted using the “Hold Roots” setting).
 Springs between each mass point (these cannot be varied). The mass of the guides is concentrated in the mass
points, the effect of which can be seen in the different spring movements.
 CINEMA 4D particle modiers are used by Hair dynamics (except for “Deector” and “Destructor”). This makes
creating effects such as wind and turbulence possible.
Settings
By default, the following settings only affect the guides. Nevertheless, if you select the “Hair” option in the “Advanced” menu of the
“Dynamics” tab, the following settings will affect each individual hair (this will also result in a dramatic increase in calculation and
render time). So, although in the following we will only refer to guides, keep in mind that what is described can also be applied to
individual hairs.
Enable
Use this setting to turn dynamics on or off for a given Hair object.
Collisions
Activate this setting if the guides should be checked for collisions with other objects. Simply assign a Collisions Tag to the collision
object.
