Geometric manipulation of modeling primitives, such as that performed by a geometry pipeline, is the first stage in computer graphics systems which perform image generation based on geometric models.
Hardware implementations of the geometry pipeline were introduced in the early Evans & Sutherland Picture System, but perhaps received broader recognition when later applied in the broad range of graphics systems products introduced by Silicon Graphics ( SGI ).
Shaders are used to program the graphics processing unit ( GPU ) programmable rendering pipeline, which has mostly superseded the fixed-function pipeline that allowed only common geometry transformation and pixel-shading functions ; with shaders, customized effects can be used.
This type of shader can generate new graphics primitives, such as points, lines, and triangles, from those primitives that were sent to the beginning of the graphics pipeline.
Level of detail techniques increases the efficiency of rendering by decreasing the workload on graphics pipeline stages, usually vertex transformations.
In 3D computer graphics, the terms graphics pipeline or rendering pipeline most commonly refers to the current state of the art method of rasterization-based rendering as supported by commodity graphics hardware.

The disadvantage to this system is that while the SAA5050 would expect to be repeatedly fed the same 40 bytes of data for every display scanline of each character row, the ULA would read a different set of 40 bytes for every display scanline in order to produce a full graphics display.
The same counter is used in both the continuous and non-continuous graphics modes and switching modes mid-frame does not cause any adjustment to the counter.
By using the palette to mask the top area of the display and taking care about when it changes mode it can shift the continuous graphics at the bottom of the display down in two pixel increments because the internal display counter is not incremented on blank scanlines during non-continuous graphics modes.
It is this latter version, which has some syntax differences from the first as well as support for the Apple II high-resolution graphics modes, that most people mean by the term " Applesoft.
The Accelerated Graphics Port ( often shortened to AGP ) is a high-speed point-to-point channel for attaching a video card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics.
This is done by adding eight extra 8-bit buses which allow the graphics controller to issue new AGP requests and commands at the same time with other AGP data flowing via the main 32 address / data ( AD ) lines.
In addition, to load a texture, a PCI graphics card must copy it from the system's RAM into the card's framebuffer, whereas an AGP card is capable of reading textures directly from system RAM using the graphics address remapping table, which reapportions main memory as needed for texture storage, allowing the graphics card to access them directly.
The graphics are generated by a custom graphics chip called MARIA which is very different from other second and third generation consoles, and made it more difficult for game programmers to make the transition.
As such, the 7800 does not include additional hardware for generating sound as it does with graphics and the sound hardware is considered the weakest part of the system.
The most substantial difference, however, is a graphics architecture which differs markedly from either the Atari 2600 VCS or Atari ’ s 8-bit line of computers.
When in “ 7800 ” mode ( signified by the appearance of the full screen Atari logo ), the graphics are generated entirely by the MARIA graphics processing unit, all system RAM is available and game data is accessed in larger 48K blocks.
The system is also notable for its forward-looking features, advanced graphics, and ambidextrous layout.
