| | Rasterisation - Wikipedia, the free encyclopedia |
 | | Rasterization is currently the most popular technique for producing real-time computer graphics. | | | The most basic rasterization algorithm takes a 3D scene, described as polygons, and renders it onto a 2D surface, usually a computer monitor. | | | While the basic rasterization process has been known for decades, modern applications continue to make optimizations and additions to increase the range of possibilities for the rasterization rendering engine. |

| | Rendering (computer graphics) - Wikipedia, the free encyclopedia |
| | Ray casting is primarily used for realtime simulations, such as those used in 3D computer games and cartoon animations, where detail is not important, or where it is more efficient to manually fake the details in order to obtain better performance in the computational stage. | | | This is called rasterization, and is the rendering method used by all current graphics cards. | | | The image is a digital image or raster graphics image. |

| | Introduction to GIS - raster based GIS |
| | Raster is a method for the storage, processing and display of spatial data. | | | See the raster spatial analysis module for information on raster data analysis. | | | In this data structure every pixel is given a single value, hence there is no compression when many like values are encountered. |

| | If we assume that rasterisation of all polygons has to be performed, visibility can be determined by one extra comparison per pixel by using the z-buffer algorithm. | | | The computational problems to be solved are transformation, clipping, visibility and rasterisation. | | | Implement and compare running times of both current and proposed scan-line algorithms. |

| | Delayed rasterisation ********************* In this version of xfsft, rasterisation is delayed, in that glyphs are rasterized on a strictly as-needed basis, which makes opening fonts much faster, especially in the case of fonts with a very large number of glyphs (such as fonts for Ideographic scripts). | | | The main problem with delayed fonts is that much of the font metric information is difficult to provide correctly. | | | Note that glyph metrics, unlike font metrics, are still computed accurately. |

| | Raster to vector - Wikipedia, the free encyclopedia |
| | Raster to vector software and hardware technology for converting raster graphics to vector graphics is used by a number of fields, most notable in conjunction with CAD and GIS systems. | | | For example drawings that only exist in physical form (blueprints, plots of lost files, etc.) can be converted into CAD files using a procedure called "Paper-to-CAD conversion" or drawing conversion, involving scanning and vectorization, or digitization. | | | Rasterisation is the opposite process of converting vector graphics to raster graphics. |

| | 4.2.3 Delayed glyph rasterisation When loading a proportional fonts which contain a huge number of glyphs, the old FreeType delayed glyph rasterisation until the time at which the glyph was first used. | | | Unlike the core fonts system, it supports features such as anti-aliasing and sub-pixel rasterisation. | | | However, the new FreeType backend has minimal problem with this, since it corrects left- and right-side bearings using `italicAngle' in the TrueType/OpenType post table, and does automatic correction of bitmap posi- tions when rasterisation so that chipped bitmaps are not displayed. |
