In [[computer graphics]], '''rasterisation''' ([[British English]]) or '''rasterization''' ([[American English]]) is the task of taking an [[Digital image|image]] described in a [[vector graphics]] format (shapes) and converting it into a [[raster image]] (a series of [[pixel]]s, dots or lines, which, when displayed together, create the image which was represented via shapes).<ref name="Worboys1995">{{cite book|author=Michael F.

Rasterization may refer to the technique of drawing [[3D model (computer graphics)|3D models]], or to the conversion of 2D [[rendering primitive]]s, such as [[polygon]]s and [[line segment]]s, into a rasterized format.
