Note: For NURBS and FFDs, physique deforms the
control points (control vertices), which, in turn
deform the model.
Pivot Point
Pivot point sets hand to the center o f the clock face.
The transform center, or pivot point, is the spot
about w hich a rotation takes place, or to and from
which a scale occurs.
All objects have a pivot point. You can think of the
pivot point as representing an object’s local center
and local coordinate system.

Pixel
Apixel(shortfor
Picture El ement)
is a single point
in a graphic im age. Graphics monitors display
pictures by dividing the screen into thousands (or
millions) of pixels, arranged in rows and columns.

Plug-Ins
A plug-in is a feature or functionality supplied
by an independent program or component.
Plug-ins can be supplied by third-party vendors or
independent sof tware develop ers.
For example, several Video Post filter and layering
plug-ins ship with 3ds Max.
The open architecture provides an API
(application programming interface) designed to
make it easy for other comp anies to write plug-ins
that extend the core functionality of 3ds Max.
