Shaders can be created on the fly from within an application, or read-in as text files, but must be sent to the driver in the form of a string. The set of APIs used to compile, link, and pass parameters to GLSL programs are specified in three OpenGL extensions, and became part of core OpenGL as of OpenGL Version 2.0.
A vertex buffer object (VBO) is an OpenGL feature that provides methods for uploading vertex data (position, normal vector, color, etc.) to the video device for non-immediate-mode rendering. VBOs offer substantial performance gains over immediate mode rendering primarily because the data reside in video device memory rather than system memory ...
The shader assembly language in Direct3D 8 and 9 is the main programming language for vertex and pixel shaders in Shader Model 1.0/1.1, 2.0, and 3.0. It is a direct representation of the intermediate shader bytecode which is passed to the graphics driver for execution.
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),
Java OpenGL (JOGL) is a wrapper library that allows OpenGL to be used in the Java programming language. [ 1 ] [ 2 ] It was originally developed by Kenneth Bradley Russell and Christopher John Kline, and was further developed by the Game Technology Group at Sun Microsystems .
There are two graphics hardware drivers: one resides inside of the X display server.There have been several designs of this driver. The current one splits it in two portions: DIX (Device-Independent X) and DDX (Device-Dependent X) Glamor will simplify the X server, and libGL-fglrx-glx [needs update] could use the libDRM of the radeon open-source driver instead of the proprietary binary blob.
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.
While nVidia has made proprietary extensions to ARB assembly languages that combine the fast compile speed of ARB assembly with modern OpenGL 3.x features, introduced with the GeForce 8 series, most non-nVidia OpenGL implementations do not provide the proprietary nVidia extensions to ARB assembly language [5] and do not offer any other way to ...
