Also discussed is the actual method for merging any two adjacent levels and several computational and storage optimizations to speed the process. Lastly, a sequence-editing system which controls precise definition of an animated sequence, is described. As the electron beam moves across each row, the beam intensity is turned on and off to create a pattern of illuminated spots. In a raster scan system, the electron beam is swept across the screen, one row at a time from top to bottom. A technique is presented for reducing the total number of merges by retaining merged groups consisting of individual levels which do not change over successive frames. There are two ways (Random scan and Raster scan) by which we can display an object on the screen. A method for the simulation of any hypothetical animation camera set-up is introduced. The term “level” refers to a single painted drawing (cel) or background. Merging is the process of combining levels of artwork into a final composite frame using digital computer graphics. This paper presents several computer methods for assisting in the production of cartoon animation, both to reduce expense and to improve the overall quality. Documents containing all frame assembly information must also be maintained. In addition, the physical limitations that these camera stands place on the manipulation of the individual artwork levels restricts the total image-making possibilities afforded by traditional cartoon animation. The task of assembling drawings and backgrounds together for each frame of an animated sequence has always been a tedious undertaking using conventional animation camera stands and has contributed to the high cost of animation production.

Find |m| and if |m| ? 1, then for every integer value of x between and excluding x1’ and x2’, calculate the corresponding value of y using the equation and scan convert (x, y). The line equation describes the coordinates of all the points that lie between the two endpoints.Ī simple approach to scan convert a line is to first scan convert P1 and P2 to pixel coordinates (x1’, y1’) and (x2’, y2’) respectively. Let the two end points of a line be P1(x1, y1) and P2(x2, y2). You can define a line by its two end points and by the line equation y = mx + c, where m is called the slope and c the y intercept of the line. You know that a line in computer graphics typically refers to a line segment, which is a portion of a straight line that extends indefinitely in opposite directions.
