UNIT-1
1.(a)Explain the common raster display system architecture with the help of a neat sketch.
(b)Explain Bresenham's circle drawing algorithm.

OR
2.(a)Differentiate ranging from boundary-fill and flood-fill algorithms.
(b)Digitize a line from point(-1,-1) to point (4,5) using Bresenham's line generation algorithm.

UNIT-2
3.(a)Let ABC is a triangle with co-ordinates A(-2,0),B(-1,1),C(-1,-1).Find the transformed co-ordinates when the triangle ABC is subjected to the anticlockwise rotation of 45* about an axis passing through the centroid of the triangle such that it is parallel to y-axis.
(b)Determine a sequence of basic transformation that are equivalent to the x-direction shearing matrix.
OR

4.(a)Explain Sutherland-Hodgeman polygon cliping algorithm.
(b)A polygon has four vertices located at A(10,10),B(10,40),C(40,10),D(40,40).Indicate transformation matrix to have its reflection about X-axis and Y-axis.

UNIT-3
5.(a)Compare and contrast the perspective projection with the parallel projection. Justify your ans that parallel projection preserve lateral measurements.
(b)Find formula of Bezier curve which passes through points (0,0) and (-2,1) and is controlled through points (7,5) and (2,0).
OR

6.(a)Explain painter's algorithm.
(b)Obtained the presective projection on the X=a plane,with centre projection being at (-1,0,0), also obtain principal vanishing projection.
OR
UNIT-4
7.(a)Explain specular reflection.is there any relation of surface tension with kind of reflection produced on the exposure of that surface to a few light source.
(b)Explain YIQ and HSV color models.

8.(a)Differentiate ranging from gouraud shading and phong shading.
(b)Explain CIE chromaticity diaagram.

OR
UNIT-5
9.(a)What are the important measure that should convey spatial and temporal content of the scene in visual representation.?
(b)Write in brief about the kind of multimedia authoring systems.
