rasteriseringsmetoder

Rasteriseringsmetoder are techniques used in computer graphics to convert vector graphics, which are defined by mathematical equations, into raster images, which are composed of pixels. This process is essential for displaying graphics on screens, as most modern displays operate on a raster-based system. Rasterisation involves several key steps, including scan conversion, which determines which pixels should be colored to represent the vector shapes, and antialiasing, which smooths the edges of shapes to reduce the appearance of jagged lines. There are various rasterisation algorithms, each with its own advantages and trade-offs in terms of speed, accuracy, and visual quality. Some common rasterisation methods include the midpoint algorithm, the Bresenham's line algorithm, and the XOR algorithm. These methods are fundamental to the rendering of graphics in applications ranging from video games to CAD software.
