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
For example, Dual Depth Peeling (2008). [2] In 2009, two significant features were introduced in GPU hardware/drivers/Graphics APIs that allowed capturing and storing fragment data in a single rendering pass of the scene, something not previously possible. These are, the ability to write to arbitrary GPU memory from shaders and atomic operations.
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 process of ordering triangle primitive vertices, calculating signed triangle area and parameter gradients between vertex attributes as a prerequisite for rasterization. [33] Triangle setup unit A fixed-function unit in a GPU that performs triangle setup (and may perform backface culling), prior to actual rasterization. [33] Trilinear filtering
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.
In order to stay multi-platform, Skia supports several (platform-dependent) back-ends. These include: CPU software rasterization; Portable Document Format (PDF) output; GPU-accelerated rendering by using: [3]

In computer graphics, a digital differential analyzer (DDA) is hardware or software used for interpolation of variables over an interval between start and end point. DDAs are used for rasterization of lines, triangles and polygons.
