OpenGL
![Video games outsource real-time rendering calculations to the GPU over OpenGL. The rendered results are not sent back to main memory, but to the framebuffer of video memory instead. The display controller will then send this data to the display device.](/Images/godic/202501/31/Linux_kernel_and_OpenGL_video_games.svg2824.png")

Open Graphics Library (OpenGL) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering.
