NURBS Surface 1075
A
NURBS object (page 3–1074)
consisting of one
or more sub-objects. The 3ds Max documentation
uses "NURBS model" to emphasize the final result
of NURBS modeling using a variety of sub-objects
and techniques.

Obj ect
An assor tment of geometric primitive objects
"Object" means an object in the scene, such as
primitive geometry like boxes and spheres, m ore
complex geometry such as Booleans, and so on.
Geometric objects are renderable. A scene can
also contain non-renderable objects such as lights,
cameras, helpers, and s pace warps.
You add objects to a scene by selecting the Create
menu or from the Create panel.
Obj ect Ins tan ce
In 3ds Max, an instance is a completely
interchangeablecloneoftheoriginalobject.
Modifying an instanced object is the same as
modifying the original.
Instances are not only alike in geometry, but also
share modifiers and materials. When you change
one instance by applying a modifier, for example,
all the other instances change with it.
Each instance has its own set of transforms, object
properties, and space warp bindings. These are
not shared among instances.
Within 3ds Max, instances derive from the same
master object. What you’re doing is applying a
single modifier to a single master object. In the
viewport,whatyouseeasmultipleobjectsare
multiple instances of the same definit ion.
For example, if you wanted to create a school
of swimming fish, you might b egin by making
many instanced copies of a single fish. You could
then animate the swimming mot ion by applying
a Ripple modifier to any fish in the school. The
whole school would swim with exactly the same
motions.
Object Moti on B l ur
Object motion blur applies a blur effect to
make fast-mov ing objects appear to move more
smoothly in animations. It is a form of "temporal
antialiasing."
