Draw distance requires definition because a processor having to render objects out to an infinite distance would slow down the application to an unacceptable speed. [1] As the draw distance increases, more distant polygons need to be drawn onto the screen that would regularly be clipped .
Microkernel pure-OpenCL "Path" render engine, supporting any number of GPUs and OpenCL-enabled CPUs concurrently. Interactive viewport rendering, including real-time material and object manipulation. Material node support. Light groups, allowing the user to change the intensity and color of lamps during the rendering process. [10]
[1] [2] [3] LOD can be decreased as the model moves away from the viewer or according to other metrics such as object importance, viewpoint-relative speed or position. LOD techniques increase the efficiency of rendering by decreasing the workload on graphics pipeline stages, usually vertex transformations. The reduced visual quality of the ...
In one example application, consider an image editing program. A user application may render the image into a viewport. As the user zooms and scrolls to view a smaller portion of the image, the application can set a clip boundary so that pixels outside the viewport are not rendered.
A view frustum The appearance of an object in a pyramid of vision When creating a parallel projection, the viewing frustum is shaped like a box as opposed to a pyramid.. In 3D computer graphics, a viewing frustum [1] or view frustum [2] is the region of space in the modeled world that may appear on the screen; it is the field of view of a perspective virtual camera system.

A viewport is a polygon viewing region in computer graphics. In computer graphics theory, there are two region-like notions of relevance when rendering some objects to an image. In textbook terminology, the world coordinate window is the area of interest (meaning what the user wants to visualize) in some application-specific coordinates, e.g ...
It is the basis of many 3D software (such as Blender, Autodesk, VTK) which are widely used. These software, available mostly on computers, are thus almost always combined with a mouse and keyboard. To provide enough DOFs (the mouse only offers 2), these software rely on modding with a key in order to separately control all the DOFs involved in ...
