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).
Examples of fields commonly represented in rasters include: temperature, population density, soil moisture, land cover, surface elevation, etc. Two sampling models are used to derive cell values from the field: in a lattice , the value is measured at the center point of each cell; in a grid , the value is a summary (usually a mean or mode) of ...
The techniques of wildlife photography differ greatly from those used in landscape photography. For example, in wildlife photography wide apertures are used to achieve a fast shutter speed, freeze the subject's motion, and blur the backgrounds, while landscape photographers prefer small apertures to keep the entire frame in focus.
Real-time rendering uses high-performance rasterization algorithms that process a list of shapes and determine which pixels are covered by each shape. When more realism is required (e.g. for architectural visualization or visual effects) slower pixel-by-pixel algorithms such as ray tracing are used instead. (Ray tracing can also be used ...

Landscape photography (often shortened to landscape photos) shows the spaces within the world, sometimes vast and unending, but other times microscopic. Landscape photographs typically capture the presence of nature but can also focus on human-made features or disturbances of landscapes. Landscape photography is done for a variety of reasons.
