OpenGL for Embedded Systems (OpenGL ES or GLES) is a subset of the OpenGL computer graphics rendering application programming interface (API) for rendering 2D and 3D computer graphics such as those used by video games, typically hardware-accelerated using a graphics processing unit (GPU). It is designed for embedded systems like smartphones ...
Immediate mode is an API design pattern in computer graphics libraries, in which . the client calls directly cause rendering of graphics objects to the display, or in which; the data to describe rendering primitives is inserted frame by frame directly from the client into a command list (in the case of immediate mode primitive rendering),
A display list, also called a command list in Direct3D 12 and a command buffer in Vulkan, is a series of graphics commands so that they may be later run when the list is executed. [1] Systems that make use of display list functionality are called retained mode systems, while systems that do not are as opposed to immediate mode systems.
In the process of rewriting the GLX calls, VirtualGL also redirects the OpenGL rendering into off-screen pixel buffers ("Pbuffers.") Meanwhile, the rest of the function calls from the application, including the ordinary X11 commands used to draw the application's user interface, are allowed to pass through VirtualGL without modification.
The OpenGL Utility Library (GLU) is a computer graphics library for OpenGL. It consists of a number of functions that use the base OpenGL library to provide higher-level drawing routines from the more primitive routines that OpenGL provides. It is usually distributed with the base OpenGL package.
The OpenGL specification describes an abstract application programming interface (API) for drawing 2D and 3D graphics. It is designed to be implemented mostly or entirely using hardware acceleration such as a GPU , although it is possible for the API to be implemented entirely in software running on a CPU .
With QuartzGL enabled, all Quartz drawing commands are translated to OpenGL commands and executed on the GPU. This differs from Quartz Extreme, which still executes Quartz drawing commands on the CPU but performs final composition using the GPU. As of OS X Mountain Lion, QuartzGL is still not enabled by default.
The OpenGL Utility Toolkit (GLUT) is a library of utilities for OpenGL programs, which primarily perform system-level I/O with the host operating system.Functions performed include window definition, window control, and monitoring of keyboard and mouse input.
