Q1. Briefly explain RGB color model. [10]
Answer.
RGB color model
The RGB color model is an additive color model in which red, green, and blue light is added together
in various ways to reproduce a broad array of colors. The name RGB comes from the initials of the
three additive primary colors, red, green, and blue. The main purpose of the RGB color model is for
the sensing, representation, and display of images in electronic systems, such as televisions and
computers, though it has also been used in
Q2. Write a note on:
· Direct view storage tubes
· Raster Scan Display
(Direct view storage tubes, Raster Scan Display) [5+5]
Answer.
Direct view storage tubes
A direct-view storage tube (DVST) stores the picture information as a charge distribution just behind
the phosphor-coated screen. It is an alternative method for maintaining a screen image to store the
picture information inside the CRT instead of refreshing the screen. Two electron guns are used in a
DVST. One, the primary gun, is used to store
Q3. Write a note on:
I. Control points

2. II. Knot Vector
(Control points, Knot Vector) [10]
Answer.
i) Control points
The control points determine the shape of the curve. Typically, each point of the curve is computed
by taking a weighted sum of a number of control points. The weight of each point varies according to
the governing parameter. For a curve of degree d, the weight of any control point is only nonzero in
d+1 intervals of the parameter space. Within those intervals, the weight changes according to a
polynomial function (basis functions) of degree d. At the boundaries of the intervals, the basis
functions go smoothly to zero, the smoothness being determined by the degree
Q4. Explain different types of coherence. [10]
Answer.
Types of coherence
Coherence is attained when there is a constant phase difference in two or more waves over time.
Two waves are said to be in phase if their crests and troughs meet at the same place at the same
time, and the waves are out of phase if the crests of one meet the troughs of another.
The waves are incoherent if the crests and troughs meet randomly.
Q5. What is multimedia? Explain briefly the uses of multimedia. [3+7]
Answer.
Multimedia
Multimedia refers to content that uses a combination of different content forms. This contrasts with
media that use only rudimentary computer displays such as text-only or traditional forms of printed
or hand-produced material. Multimedia includes a combination of text, audio, still images,
animation, video, or interactivity content forms.
Q6. Explain the following
(a) Full animation
(b) Limited animation
(c) Rotoscoping
(Full animation, Limited animation, Rotoscoping) [4+3+3]
Answer.
a) Full animation
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,
