➢ Joystick is used as a positioning device,which uses a small vertical lever(stick) mounded on a base.It is used to steer the screen cursor around and select screen position with the stick movement. ➢ A push or pull on the stick is measured with strain gauges and converted to movement of the screen cursor in […]
➢ A trackball is a ball device that can be rotated with the fingers or palm of the hand to produce screen cursor movement. ➢ Laptop keyboards are equipped with a trackball to eliminate the extra space required by a mouse. ➢ Spaceball is an extension of two-dimensional trackball concept. ➢ Spaceballs are used for […]
❖ The disadvantages of encoding runs are that color changes are difficult to record and storage requirements increase as the lengths of the runs decrease. ❖ In addition, it is difficult for the display controller to process the raster when many short runs are involved. ❖ Moreover, the size of the frame buffer is no […]
Method 1: Using circle symmetry property, we generate the circle path with vertical spans in the octant from x = 0 to x = y, and then reflect pixel positions about the line y = x to y=0 Method 2: Another method for displaying thick curves is to fill in the area between two Parallel […]
Typically, system activity is governed by the sequence of primitive or atomic operations it is executing. Usually, a machine level instruction, which is indivisible, instantaneous, and cannot be interrupted ( unless the system fails), corresponds to an atomic operation. However, it is desirable to be able to group such instructions that accomplish a certain task […]

We specify parameters and activate the routines for Bézier-curve display with the OpenGL functions glMap1* (GL_MAP1_VERTEX_3, uMin, uMax, stride, nPts, *ctrlPts); glEnable (GL_MAP1_VERTEX_3); We deactivate the routines with glDisable (GL_MAP1_VERTEX_3); where, A suffix code of f or d is used with glMap1 to indicate either floating-point or doubleprecision for the data values. Minimum and maximum […]

Bubble sort is a simple sorting algorithm. The algorithm starts at the beginning of the data set. It compares the first two elements, and if the first is greater than the second, it swaps them. It continues doing this for each pair of adjacent elements to the end of the data set. It then starts […]
