on the sphere and solving the simulation. The result is that the sphere falls
under the force of gravity.
You can use dynamics objects on page 880, dynamics space warp deflectors
(
PDynaFlect on page 2738, SDynaFlect on page 2745, and UDynaFlect on page 2748),
and space warp forces such as
Gravity on page 2721 and Wind on page 2724 to
add complexity to a simulation. You can use a particle stream from a particle
emitter as a force on an object: the particles can collide with and be deflected
by the object, as well as move it. You can attach special dynamics objects to
objects, such as
Spring on page 890 to simulate the effects of a spring.
You can combine effects: Wind, gravity, a spring object, collision, particle
deflection and collision, as well as surface properties such as friction, can all
work on an object in a simulation. For a full understanding of what dynamics
can do, explore this topic and areas of 3ds Max that pertain to dynamics.
Dynamics-Specific Areas in 3ds Max
The Dynamics Utility (this topic)
The Dynamics Utility is the main control center for dynamics simulations.
You specify which objects are used in the simulation, what their interactivity
is with each other and with the effects in the scene. The simulation is then
"solved," generating the keyframes.
The effects of collisions between objects depend on the velocity of the objects
and their properties. For collision to work between two objects, each object
must have the other object assigned for collision. For example, when bouncing
a ball, both the floor and the ball are assigned collisions.
The Material Editor: The
Dynamics Properties rollout on page 5423 in the
Material Editor lets you assign the dynamics properties to the surface of an
object, like friction and bounce. Using a multi/sub-object material, you can
have different surface properties at the face level of any object.
NOTE You can override material surface dynamic properties with controls on the
Edit Object dialog on page 3867 in the Dynamics utility.
Dynamics Objects, Particles and Dynamics, Dynamics Interface: Special objects
like Spring and Damper, Space Warp forces like Gravity and Wind, as well as
Space Warp deflectors like PDynaFlect can all influence a dynamics simulation.
You must create these objects and space warps first in other areas of 3ds Max
before you can use them in a dynamics simulation. See the following topics
for details on their creation and use:
