Computergraphics lighting refers to the simulation of light in computergraphics . This simulation can either be extremely accurate, as is the case in an Application software application like Radiance software Radiance which attempts to track the energy flow of light interacting with materials using Radiosity computergraphics radiosity computational techniques. Alternatively, the simulation can simply be inspired by light physics , as is the case with non photorealistic rendering . In both cases, a shading model is used to describe how surfaces respond to light.

In a typical case, a fragment may be discarded if it is farther away than the pixel that is already at that location according to the depth buffer . If it is nearer than the existing pixel, it may replace what is already there, or, if alpha blending is in use, the pixel s color may be replaced with a mixture of the fragment s color and the pixel s existing color, as in the case of drawing a translucent object.

Unreferenced date December 2009 In computergraphics , planar is the method of representing pixel colours with several bit plane bitplanes of Random Access Memory RAM . Each bit in a bitplane is related to one pixel on the screen. Unlike Packed pixel Chunky , Highcolour or Truecolor Truecolour graphics, the whole data for an individual pixel isn t in one specific location in RAM, but spread across the bitplanes that make up the display. For example, on a Packed pixel chunky display, each byte represents one pixel. Three pixels in a row would be stored as follows, where up to 256 different colours are available Byte 0 00000000 Black pixel br Byte 1 00000001 Blue pixel br Byte 2 00000010 Green pixel Whereas a planar data store could use 2 bitplanes, providing for a 4 colour display A row of 8 black pixels br Plane 0, Byte 0 00000000 br Plane 1, Byte 0 00000000 A row of 1 blue pixel, 2 black pixels, 1 green pixel, 4 black pixels br Plane 0, Byte 0 10000000 br Plane 1, Byte 0 00010000 Adding a third plane would make 2 sup 3 sup 8 colours available. Where fewer than 256 colours are needed, planar graphics are more economical in RAM compared with chunky graphics. Example to display 8 colours using 3 bitplanes, so each pixel has 3 bits assigned to it instead of 8, reduces memory and bandwidth requirements by 62.5 . This saving was most significant in the 80s and early 90s when fast RAM was expensive and most computergraphics displayed fewer than 256 colours. A disadvantage of planar graphics is that more RAM address cycles are needed for scrolling and animation s, although these operations can be made faster by dedicated hardware.

See also Vertex graph theory A vertex plural vertices in computergraphics is a data structure that describes a point in 2D or 3D space . Display objects are composed of arrays of flat surfaces typically triangles and vertices define the location and other attributes of the corners of the surfaces. Application to object models In computergraphics, objects are most often represented as triangulated Polyhedron polyhedra . Non triangular surfaces can be converted to an array of triangles through tessellation . The vertices of triangles are associated not only with position but also with other graphical attributes used to render the object correctly. Such attributes can include color at the vertex point, reflectance of the surface at the vertex, textures of the surface at the vertex, and the normal of an approximated curved surface at the location of the vertex. These properties are used in rendering by a vertex shader or vertex pipeline . The normal can be used to determine a surface s orientation toward a light source for flat shading using Lambert s cosine law , or the orientation of each of the vertices to mimic a curved surface with Phong shading . Vertex attributes Most attributes of a vertex represent vectors in the space to be Rendering computergraphics rendered .

dablink This article pertains to computergraphics . For the connotation pertaining to the Global Positioning System , see Dilution of precision GPS . Dilution of precision is an algorithmic trick used to handle difficult problems in hidden line removal , caused when horizontal and vertical edges lay on top of each other due to numerical instability . Numerically, the severity escalates when a CAD model is viewed along the principal axii or when a geometric form is viewed end on. The trick is to alter the view vector by a small amount, thereby hiding the flaws. Unfortunately, this mathematical modification introduces new issues of its own, namely that the exact nature of the original problem has been destroyed, and visible artifacts of this kludge will continue to haunt the algorithm. One such issue is that edges that were well defined and hidden will now be problematic. Another common issue is that the bottom edges on circles viewed end on will often become visible and propagate their visibility throughout the problem.
