WebOct 7, 1999 · Other Uses for the Line Algorithm A line can be represented by the equation y = mx + c, where m = deltay / deltax. Note that this is a version of the standard linear equation ax + bx + c = 0. There are many algorithms which use this equation. One good use for the Bresenham line algorithm is for quickly drawing filled concave polygons (eg ... WebSep 15, 2009 · You run Bresenham, but for each pixel (x,y), you actually draw (x,y), (x,y+1), ... (x,y+4). And if you want the ends of the line to be rounded, draw a circle at each end. For overkill, make a pixel map of the stylus (a circle or diagonal nib, or whatever), then draw a set of parallel Bresenham lines, one for each pixel in the stylus. Share

To derive Bresenham's algorithm, two steps must be taken. The first step is transforming the equation of a line from the typical slope-intercept form into something different; and then using this new equation to draw a line based on the idea of accumulation of error. Line equation The slope-intercept … See more Bresenham's line algorithm is a line drawing algorithm that determines the points of an n-dimensional raster that should be selected in order to form a close approximation to a straight line between two points. … See more Bresenham's line algorithm is named after Jack Elton Bresenham who developed it in 1962 at IBM.
