In computer graphics, the render output unit (ROP) or raster operations pipeline is a hardware component in modern graphics processing units (GPUs) and one of the final steps in the rendering process of modern graphics cards.
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 word "raster" has its origins in the Latin rastrum (a rake), which is derived from radere (to scrape). It originates from the raster scan of cathode-ray tube (CRT) video monitors, which draw the image line by line by magnetically or electrostatically steering a focused electron beam. [3]
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]
Raster graphic image. 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 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.
Rasterization can be performed using devices based on a stream computing model, one triangle at the time, and access to the complete scene is needed only once. [ a ] The drawback of rasterization is that non-local effects, required for an accurate simulation of a scene, such as reflections and shadows are difficult; and refractions [ 2 ] nearly ...
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.
