CINEMA 4D R11 Quickstart – Dynamics
In order to make a simulation possible in the first make all objects, including gravitation, sub-objects of the
solver object. Objects lying outside of the solver object will not be included in the simulation. This allows the
creation of several optimized simulations within one scene which are completely independent of one another.
If you make just a few changes to the properties of the Dynamic Tags of the polygon object, you’ll have your
very first Dynamics simulation – but we don’t want to take the wind out of our Quickstart sails just yet. So we’ll
give you a few facts about each component and how they work together.
The solver object is the star of the Dynamics module. It takes over all calculations in dynamic simulations of
its sub-objects and bodies. You determine the algorithm to be used and the distance between the objects that
are to collide (Epsilon > Eps).
The base object refers to the object required for the Dynamics simulation. You can use parametric objects which
have been converted to polygon objects or imported polygon objects.
The Dynamics tags give the object its character. They let a polygon object behave like a hard metal or wood body
on the one hand or a rubber ring or pudding on the other. Only your fantasy is the limit! There are three types
of Dynamics tags: The Rigid Body Dynamic Tag is for bodies with a hard surface. The Rigid Body Spring Tag lets
you attach springs to polygon objects. Each point of an object can serve as a “spring“. An example of this would
be a figure hung on metal springs or the classic jack-in-the-box. The Soft Body Spring Tag is used mainly in soft
bodies, for example rubber balls, or dog’s ears. This can also be done using the CINEMA 4D module, Clothilde.
With effectors we have gravitation, drag and wind. You generate the gravitation and apply drag to the object,
which forces the animation to end eventually. Without drag a rolling ball, for example, would never stop rolling
and a rubber ball would never stop bouncing! If you can’t wait to follow in Isaac Newton’s footsteps, flip to
the next chapter.
