Immediate Mode (computer Graphics)
Immediate mode is an application programming interface, API design pattern in computer graphics libraries, in which * the Client (computing), client calls directly cause Rendering (computer graphics), rendering of graphics objects to the display, or in which * the data to describe rendering primitives is inserted Film frame, frame by frame directly from the Client (computing), client into a command list (in the case of ''#Immediate mode primitive rendering, immediate mode primitive rendering''), without the use of extensive indirection – thus'' immediate ''– to retained resources. It does not preclude the use of Multiple buffering, double-buffering. Retained mode is an alternative approach. Historically, retained mode has been the dominant style in Graphical user interface, GUI libraries; however, both can coexist in the same library and are not necessarily exclusive in practice. Overview In immediate mode, the scene (complete object model of the rendering primitives) is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Direct Mode
In computing, direct or immediate mode in an interactive programming system is the immediate execution of commands, statements, or expressions. In many interactive systems, most of these can both be included in programs or executed directly in a read–eval–print loop (REPL). Most interactive systems also offer the possibility of defining programs in the REPL, either with explicit declarations, such as Python's def, or by labelling them with line numbers. Programs can then be run by calling a named or numbered procedure or by running a main program. Many programming systems, from Lisp and JOSS to Python and Perl have interactive REPLs which also allow defining programs. Most integrated development environments offer a direct mode where, during debugging In engineering, debugging is the process of finding the Root cause analysis, root cause, workarounds, and possible fixes for bug (engineering), bugs. For software, debugging tactics can involve interactive debugging, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Retained Mode
Retained mode in computer graphics is a major pattern of API design in graphics libraries, in which * the graphics library, instead of the client, retains the scene (complete object model of the rendering primitives) to be rendered and * the client calls into the graphics library do not directly cause actual rendering, but make use of extensive indirection to resources, managed thus ''retained'' by the graphics library. It does not preclude the use of double-buffering. Immediate mode is an alternative approach. Historically, retained mode has been the dominant style in GUI libraries; however, both can coexist in the same library and are not necessarily exclusionary in practice. Overview In retained mode the client calls do not directly cause actual rendering, but instead update an abstract internal model (typically a list of objects) which is maintained within the library's data space. This allows the library to optimize when actual rendering takes place along wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indirection (computing)
Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. The various addressing modes that are defined in a given instruction set architecture define how the machine language instructions in that architecture identify the operand(s) of each instruction. An addressing mode specifies how to calculate the effective memory address of an operand by using information held in registers and/or constants contained within a machine instruction or elsewhere. In computer programming, addressing modes are primarily of interest to those who write in assembly languages and to compiler writers. For a related concept see orthogonal instruction set which deals with the ability of any instruction to use any addressing mode. Caveats There are no generally accepted names for addressing modes: different authors and computer manufacturers may give different names to the same addressing mode, or the same names to different addressing modes.

Shaders
In computer graphics, a shader is a computer program that calculates the appropriate levels of light, darkness, and color during the rendering of a 3D scene—a process known as '' shading''. Shaders have evolved to perform a variety of specialized functions in computer graphics special effects and video post-processing, as well as general-purpose computing on graphics processing units. Traditional shaders calculate rendering effects on graphics hardware with a high degree of flexibility. Most shaders are coded for (and run on) a graphics processing unit (GPU), though this is not a strict requirement. ''Shading languages'' are used to program the GPU's rendering pipeline, which has mostly superseded the fixed-function pipeline of the past that only allowed for common geometry transforming and pixel-shading functions; with shaders, customized effects can be used. The position and color ( hue, saturation, brightness, and contrast) of all pixels, vertices, and/or tex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Graphics Processing Unit
A graphics processing unit (GPU) is a specialized electronic circuit designed for digital image processing and to accelerate computer graphics, being present either as a discrete video card or embedded on motherboards, mobile phones, personal computers, workstations, and game consoles. GPUs were later found to be useful for non-graphic calculations involving embarrassingly parallel problems due to their parallel structure. The ability of GPUs to rapidly perform vast numbers of calculations has led to their adoption in diverse fields including artificial intelligence (AI) where they excel at handling data-intensive and computationally demanding tasks. Other non-graphical uses include the training of neural networks and cryptocurrency mining. History 1970s Arcade system boards have used specialized graphics circuits since the 1970s. In early video game hardware, RAM for frame buffers was expensive, so video chips composited data together as the display was being scann ...
