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 ren ...

Graphics Accelerator
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 scanned out o ...
