Three-dimensional real-time gRAphics are a prevalent technology nowadays, thanks
to the steady rise of processing power and specialized gRAphics hardware. One of the
goals of computer gRAphics most sought after and difficult to achieve is to reproduce realistic outdoor environments featuring dense forests.
This is the machine-generated representation of a Handle gRAphics object and its children. Note that handle values may change when these objects
are re-created. This may cause problems with any callbacks written to
depend on the value of the handle at the time the object was saved.
Many applications in computer gRAphics require complex, highly
detailed models. However, the level of detail actually necessary
may vary considerably. To control processing time, it is often desirable
to use approximations in place of excessively detailed models.
The creation of believable and endearing characters in computer
gRAphics presents a number of technical challenges, including the
modeling, animation and rendering of complex shapes such as
heads, hands, and clothing.
