introduction in 1992, OpenGL has become the industry's most
widely used and supported 2D and 3D graphics application
programming interface (API), bringing thousands of
applications to a wide variety of computer platforms. OpenGL
fosters innovation and speeds application development by
incorporating a broad set of rendering, texture mapping, special
effects, and other powerful visualization functions. Developers
can leverage the power of OpenGL across all popular desktop
and workstation platforms, ensuring wide application
deployment.
Parenting
Parenting is the process of creating a hierarchical organization
of objects in a scene. In parenting, an object (called the parent
object) is "parented" to another object (called the child object).
Parenting relationships can be nested to any degree, so that
one or more objects are the children of another object, which is
in turn the child of another.
Transformations of the parent object affect all child objects
(sometimes called "descendants") as well. The effect is to
allow separately modeled objects to be used in a scene as a
single functional unit. For example, the chest of a human
character may be made the parent of the two arms. In this
manner, the arms will stay connected to the chest as the chest
is rotated or translated. Likewise, the arms will be scaled up
and down as the chest is resized. The arms, however, as child
objects, can be transformed without affecting the chest
Pipelining
AGP graphics boards can queue multiple commands using a
method called pipelining. In pipelining, AGP overlaps the
memory or bus access times for a request with the issuing of
following requests. In the PCI bus, the second request does
not begin until the data transfer of the first request finishes.
Primitives
Primitives are the basic 3D geometric shapes that are
automatically generated by 3D modeling applications, and
which therefore need not be constructed from scratch. A very
