Order-independent Transparency
Order-independent transparency (OIT) is a class of techniques in rasterization, rasterisational computer graphics for rendering Transparency (graphic), transparency in a 3D scene, which do not require rendering geometry in sorted order for alpha compositing. Description Commonly, 3D geometry with transparency is rendered by blending (using alpha compositing) all surfaces into a single buffer (think of this as a canvas). Each surface occludes existing color and adds some of its own color depending on its ''alpha'' value, a ratio of light ''transmittance''. The order in which surfaces are blended affects the total occlusion or ''visibility'' of each surface. For a correct result, surfaces must be blended from farthest to nearest or nearest to farthest, depending on the alpha compositing operation, ''over'' or ''under''. Ordering may be achieved by rendering the geometry in sorted order, for example sorting triangles by depth, but can take a significant amount of time, not always produ ...

Rasterization
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 rasterized image may then be displayed on a computer display, video display or printer, or stored in a bitmap file format. Rasterization may refer to the technique of drawing 3D models, or to the conversion of 2D rendering primitives, such as polygons and line segments, into a rasterized format. Etymology The term "rasterisation" comes . 2D images Line primitives Bresenham's line algorithm is an example of an algorithm used to rasterize lines. Circle primitives Algorithms such as the midpoint circle algorithm are used to render circles onto a pixelated canvas. 3D images Rasterization is one of the typical techniques of rendering 3D models. ...

Dreamcast
The is the final home video game console manufactured by Sega. It was released in Japan on November 27, 1998, in North America on September 9, 1999 and in Europe on October 14, 1999. It was the first sixth-generation video game console, preceding Sony's PlayStation 2, Nintendo's GameCube, and Microsoft's Xbox. The Dreamcast's discontinuation in 2001 ended Sega's 18 years in the console market. A team led by Hideki Sato began developing the Dreamcast in 1997. In contrast to the expensive hardware of the unsuccessful Saturn, the Dreamcast was designed to reduce costs with off-the-shelf components, including a Hitachi SH-4 CPU and an NEC PowerVR2 GPU. Sega used the GD-ROM media format to avoid the expenses of DVD-ROM technology. Developers were able to include a custom version of the Windows CE operating system on game discs to make porting PC games easy, and Sega's NAOMI arcade system board allowed nearly identical conversions of arcade games. The Dreamcast was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

External Sorting
External sorting is a class of sorting algorithms that can handle massive amounts of data. External sorting is required when the data being sorted do not fit into the main memory of a computing device (usually RAM) and instead they must reside in the slower external memory, usually a disk drive. Thus, external sorting algorithms are external memory algorithms and thus applicable in the external memory model of computation. External sorting algorithms generally fall into two types, distribution sorting, which resembles quicksort, and external merge sort, which resembles merge sort. External merge sort typically uses a hybrid sort-merge strategy. In the sorting phase, chunks of data small enough to fit in main memory are read, sorted, and written out to a temporary file. In the merge phase, the sorted subfiles are combined into a single larger file. Model External sorting algorithms can be analyzed in the external memory model. In this model, a cache or internal memo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Single Instruction Multiple Threads
Single instruction, multiple threads (SIMT) is an execution model used in parallel computing where single instruction, multiple data (SIMD) is combined with zero-overhead Thread (computing)#Multithreading, multithreading, i.e. multithreading where the hardware is capable of switching between threads on a cycle-by-cycle basis. There are two models of multithreading involved. In addition to the zero-overhead multithreading mentioned, the SIMD execution hardware is virtualized to represent a multiprocessor, but is inferior to a SPMD processor in that instructions in all "threads" are executed in lock-step in the lanes of the SIMD processor which can only execute the same instruction in a given cycle across all lanes. The SIMT execution model has been implemented on several GPUs and is relevant for general-purpose computing on graphics processing units (GPGPU), e.g. some supercomputers combine CPUs with GPUs. The processors, say a number of them, seem to execute many more than tasks. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Approximate OIT
An approximation is anything that is intentionally similar but not exactly equal to something else. Etymology and usage The word ''approximation'' is derived from Latin ''approximatus'', from ''proximus'' meaning ''very near'' and the prefix ''ad-'' (''ad-'' before ''p'' becomes ap- by assimilation) meaning ''to''. Words like ''approximate'', ''approximately'' and ''approximation'' are used especially in technical or scientific contexts. In everyday English, words such as ''roughly'' or ''around'' are used with a similar meaning. It is often found abbreviated as ''approx.'' The term can be applied to various properties (e.g., value, quantity, image, description) that are nearly, but not exactly correct; similar, but not exactly the same (e.g., the approximate time was 10 o'clock). Although approximation is most often applied to numbers, it is also frequently applied to such things as mathematical functions, shapes, and physical laws. In science, approximation can refer to u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
