Fast line drawing is a fundamental operation on which many other routines are built – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow. OpenGL (Open Graphics Library) is the computer industry's standard application program interface ( API) for defining 2-D and 3-D graphic images. 12 DDA Algorithm. A line segment between points is given by the convex combinations of those points; if the "points" are images, the line segment is a simple morph between the images. Step 2: Calculate dx and dy. – The display size is 320x240 pixels and is RGB565 format – The box will be drawn from (100,50) to (220, 190) – The box top is red, the bottom is blue, and the sides green. This example lets the user draw and move line segments. If you have an optimized program than listed on our site, then you can mail us with your name and a maximum of 2 links are allowed for a guest post. development of line drawing algorithms ended with Bresenham's famous algorithm. Write and explain DDA line drawing algorithm.
