In computer graphics, rasterisation (British English) or rasterization (American English) is the task of taking an image described in a vector graphics format (shapes) and converting it into a raster image (a series of pixels, dots or lines, which, when displayed together, create the image which was represented via shapes).
The pixel pipelines take pixel (each pixel is a dimensionless point) and texel information and process it, via specific matrix and vector operations, into a final pixel or depth value; this process is called rasterization. Thus, ROPs control antialiasing, when more than one sample is merged into one pixel.
This means that a GPU can speed up any rendering algorithm that can be split into subtasks in this way, in contrast to 1990s 3D accelerators which were only designed to speed up specific rasterization algorithms and simple shading and lighting effects (although tricks could be used to perform more general computations).

The rasterization step is the final step before the fragment shader pipeline that all primitives are rasterized with. In the rasterization step, discrete fragments are created from continuous primitives. In this stage of the graphics pipeline, the grid points are also called fragments, for the sake of greater distinctiveness.
The Skia Graphics Engine or Skia is an open-source 2D graphics library written in C++.Skia abstracts away platform-specific graphics APIs (which differ from one to another). [1]
Real-time graphics systems must render each image in less than 1/30th of a second. Ray tracing is far too slow for these systems; instead, they employ the technique of z-buffer triangle rasterization. In this technique, every object is decomposed into individual primitives, usually triangles.
Fragment processing is a term in computer graphics referring to a collection of operations applied to fragments generated by the rasterization operation in the rendering pipeline. During the rendering of computer graphics, the rasterization step takes a primitive , described by its vertex coordinates with associated color and texture ...
S3 Graphics' Chrome series of graphics accelerators arrived in 2004 with the DeltaChrome line of chips. They were supplied as discrete, mobile, or integrated graphics. They were supplied as discrete, mobile, or integrated graphics.
