Computer graphics-Refresh buffer or frame buffer
Here we learn about some of the concepts of Computer Graphics : *Raster Scan Displays *Refresh buffer or frame buffer: This memory area holds the set of intensity values for all the screen points. Stored intensity values then retrieved from refresh buffer and “painted” on the screen one row (scan line) at a time *Random Scan Displays Random scan displays have higher resolution than raster systems. Vector displays product smooth line drawing. A raster system produces jagged lines that are plotted as discrete points sets.
Computer Graphics-Bresenham’s Line Algorithm
Here we learn about some of the concepts of Computer Graphics : Bresenham’s Line Algorithm A highly efficient incremental method for scan converting lines. Using only incremental integer calculation. DDA works with floating point arithmetic Rounding to integers necessary Bresenham’s algorithm uses integer arithmetic Constants need to be computed only once
