A framebuffer (frame buffer, or sometimes framestore) is a portion of random-access memory (RAM) [1] containing a bitmap that drives a video display. It is a memory buffer containing data representing all the pixels in a complete video frame . [ 2 ]
The term quad buffering is the use of double buffering for each of the left and right eye images in stereoscopic implementations, thus four buffers total (if triple buffering was used then there would be six buffers). The command to swap or copy the buffer typically applies to both pairs at once, so at no time does one eye see an older image ...
RFB ("remote framebuffer") is an open simple protocol for remote access to graphical user interfaces.Because it works at the framebuffer level it is applicable to all windowing systems and applications, including Microsoft Windows, macOS, the X Window System and Wayland.
The frame buffer object architecture (FBO) is an extension to OpenGL for doing flexible off-screen rendering, including rendering to a texture.By capturing images that would normally be drawn to the screen, it can be used to implement a large variety of image filters, and post-processing effects.
Triple Buffering may result in a frame being discarded without being displayed if two or more newer frames are completely rendered in the time it takes for one frame to be sent to the display. By contrast, Direct3D swap chains are a strict first-in, first-out queue , so every frame that is drawn by the application will be displayed even if ...
DirectFB (Direct Frame Buffer), now continued as DirectFB2, is a software library with a small memory footprint that provides graphics acceleration, input device handling and abstraction layer, and integrated windowing system with support for translucent windows and multiple display layers on top of the Linux framebuffer without requiring any kernel modifications.
In computer science, a data buffer (or just buffer) is a region of memory used to store data temporarily while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers); however, a buffer may be used when data is moved between processes ...
As a scene is drawn, drawing primitives (the basic elements of graphics output, such as points, lines, circles, text etc. [1]) are rasterized into fragments which are textured and combined with the existing frame buffer. How a fragment is combined with the data already in the frame buffer depends on various settings.
