List Of Rendering APIs
Rendering APIs typically provide just enough functionality to abstract a graphics accelerator, focussing on rendering primitives, state management, command lists/command buffers; and as such differ from fully fledged 3D graphics libraries, 3D engines (which handle scene graphs, lights, animation, materials etc.), and GUI frameworks; Some provide fallback software rasterisers, which were important for compatibility and adoption before graphics accelerators became widespread. Some have been extended to include support for compute shaders. Low level rendering APIs typically leave more responsibility with the user for resource memory management, and require more verbose control, but have significantly lower CPU overhead, ''and'' allow greater utilisation of multicore processors. 2D rendering APIs * OpenVG * Direct2D * Quartz 2D * Anti-Grain Geometry (AGG) * Simple DirectMedia Layer (SDL) * Simple and Fast Multimedia Library (SFML) * X11 * Cairo * Skia * Qt GUI primitive rende ...

Graphics Accelerator
A graphics processing unit (GPU) is a specialized electronic circuit designed to manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles. Modern GPUs are efficient at manipulating computer graphics and image processing. Their parallel structure makes them more efficient than general-purpose central processing units (CPUs) for algorithms that process large blocks of data in parallel. In a personal computer, a GPU can be present on a video card or embedded on the motherboard. In some CPUs, they are embedded on the CPU die. In the 1970s, the term "GPU" originally stood for ''graphics processor unit'' and described a programmable processing unit independently working from the CPU and responsible for graphics manipulation and output. Later, in 1994, Sony used the term (now standing for ''graphics processing unit'') i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
