Rasterointiprosessi

Rasterointiprosessi, also known as rasterization, is a fundamental process in computer graphics and digital imaging. It involves converting vector graphics, which are defined by mathematical equations, into a raster image, which is a grid of pixels. This process is crucial for displaying graphics on raster displays, such as computer monitors and televisions, which operate by illuminating pixels.

The rasterization process begins with the vector graphic, which consists of lines, curves, and shapes defined by coordinates and mathematical equations. These vector graphics are often created using software like Adobe Illustrator or CorelDRAW. The rasterization process then converts these vector graphics into a bitmap image, where each pixel is assigned a specific color value.

The rasterization process involves several steps. First, the vector graphic is scaled to fit the desired output size. Then, the graphic is divided into a grid of pixels. Each pixel is assigned a color value based on the vector graphic's mathematical equations. This process is known as antialiasing, which helps to smooth the edges of the graphic and reduce the appearance of jagged lines.

Once the rasterization process is complete, the resulting bitmap image can be displayed on a raster display. The raster display then illuminates the pixels to create the final image. This process is repeated for each frame of an animation or video, allowing for smooth and continuous motion.

Rasterization is widely used in various applications, including computer graphics, digital imaging, and video production. It is also used in 3D rendering, where vector graphics are converted into raster images to create realistic images and animations. Overall, rasterization is a critical process in the field of computer graphics and digital imaging, enabling the creation and display of high-quality images and animations.
