BCA5042– Graphics and Multimedia

Qus:1 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 'cartoony'

Qus:2 Discuss Bresenham’s line drawing algorithm.

Answer:                                             

The Bresenham's line-drawing algorithm is based on drawing an approximation of the true line. The true line

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 clipping algorithm clips any polygon against a convex clip polygon. The Weiler- Atherton clipping

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

Qus:6 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
