Algorithms for Basic Line Segment Plotting
There are two important algorithms for basic line segment plotting-DDA algorithm and Bresenham algorithm. Both the algorithms use the form y = mx + c of the line segment.
Whereas DDA uses floating point calculations to determine iteratively the pixel positions, Bresenham algorithm is based purely on integer calculation. Therefore, Bresenham algorithm is more efficient and faster.
However, in the literature, you may find modified DDA algorithm that uses integer calculation only.
Assumptions for Area Subdivision Method a) ¾ Plane of projection is z=0 plane b) ¾ Orthographic parallel projections c) ¾ Direction of projection as d= (0,0,-1) d
Transformation for parallel projection Parallel projections is also termed as Orthographic projection, are projections into one of the coordinate planes as x = 0, y = 0 or z
Types of Refresh Monitors - Raster Scan and Random Scan There are two types of refresh monitors, i.e. the Raster Scan and Random Scan that will be illustrated separately.
