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.
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).
Advances in GPU technology have made real-time ray tracing possible in games, although it is currently almost always used in combination with rasterization. [ 29 ] : 2 This enables visual effects that are difficult with only rasterization, including reflection from curved surfaces and interreflective objects, [ 50 ] : 305 and shadows that are ...
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.
Windows Advanced Rasterization Platform (WARP) [1] is a software rasterizer and a component of DirectX graphics runtime in Windows 7 and later. It is available for Windows Vista and Windows Server 2008 through platform update for Windows Vista .
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]
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 ...
