Qus:1 Explain the different types of
plotter.
Answer: Plotters are special output devices
used to produce hard copies of large graphs and designs on paper. Plotters are
often used for the production of construction maps, engineering drawings,
architectural plans and business charts. They can be a component that is added
to your computer system and
Qus:2 Discuss Bresenham’s line
drawing algorithm.
Answer:
Qus:3 Discuss mid-point circle
algorithm.
Answer: In computer graphics, the midpoint
circle algorithm is an algorithm used to determine the points needed for
drawing a circle. The algorithm is a variant of Bresenham's line algorithm, and
is thus sometimes known as Bresenham's circle algorithm.
Let's simplify the
Qus:4 Explain polygon clipping.
Answer: A polygon is usually defined by a
sequence of vertices and edges. If the polygons are unfilled, line-clipping
techniques are sufficient however, but if the polygons are filled, the process
in more complicated. A polygon may be fragmented into several polygons in the
clipping process, and the original colour associated with each one. The
Sutherland-Hodgeman
Qus:5 Discuss the parametric spline
curves
Answer: Parametric equations can be used to
generate curves that are more general than explicit equations of the form
y=f(x). A
Qus:6 Explain the following
(a) Full animation
(b) Limited animation
(c) Rotoscoping
Answer: (a)
Full animation refers
to the process of producing high-quality traditionally animated films, which
regularly use detailed drawings and possible movement. Fully animated films can
be done in a variety of styles, from more realistically animated works such as
those produced by the Walt Disney
studio (Beauty and the Beast, Aladdin, Lion King) to the more
