FIFTH SEMESTER EXAMINATION, 2008
COMPUTER GRAPHICS
Time Durations: Three Hours Total Marks: 70
Instruction: Attempt any five questions. All questions carry equal marks.
1 (a). Describe the operating characteristics of raster refresh system, vector refresh system and LCD.
(b). Consider three raster scan system having resolutions 1024 and 2560 2048. What size frame buffer is required for each of these systems to store 12 bits per pixel?
2 Derive the decision parameters that can be used to generate straight line segments with any slop using mid point method.
3 (a). Write the procedure to fill the interior of a given ellipse with specified patterns.
(b) Devise an algorithm for antialising elliptical boundaries.
4 (a). Implement the scan line algorithm to apply any specified rectangular fill pattern to a polygon interior.
(b) Write any circle generating algorithm with radius and center position ().
5 (a). Show that two successive reflection about either of the coordinate axes is equivalent to a single rotation about the coordinate origin.
(b). Write a routine to implement rotation in increments of 90 in frame buffer block transfers.
6 (a). Write an algorithm to implement scaling as a raster transformation of a pixel block.
(b). Describe the application of translation, rotation and scaling of an object with suitable example.
7 (a). Derive the matrix representation for a workstation transformation.
(b). Write the procedure to clip an ellipse against a rectangular window.
8 (a). Derive the transformation matrix for scaling an object by a scaling factor S in a direction defined by the direction angels .
(b). Write a procedure to perform a one-point perspective projection of an object.
The game variety is one of many major causes to think about.
