Each extension is associated with a short identifier, based on the name of the company which developed it. That is, the basic structure of an object can change at any time, even if the rendering pipeline is asynchronously using that object. For the same reason, OpenGL is purely concerned with rendering, providing no APIs related to input, audio, or windowing. Most complaints revolved around the lack of communication by Khronos to the development community and multiple features being discarded that were viewed favorably by many. From this version onwards, it’s not possible to access new features using a full context , or to access deprecated features using a forward-compatible context. The DrawElements API is extended to automatically add a numerical offset the base vertex to each array index.

Objects would also be immutable; however, they could have their contents changed and updated. Support for floating-point and non-normalized integer texture storage. opengl 2.1
OpenGL and Intel graphics
The opengl 2.1 version openhl OpenGL, version 1. Opengl 2.1 is, the basic structure of an object can change at any time, even if the rendering pipeline is asynchronously using that object.
Alongside the release of OpenGL 1. Allow fragment shaders to read fragment coordinate locations in the same conventions as Direct3D.
The display controller will then send this data to the display device. Under the Longs Peak API, object creation would become atomicusing opengl 2.1 to define the properties of an object opengl 2.1 would be created with one function call.
The specification was circulated among a few interested parties — but never turned into a product. Standards of the Khronos Group. Haswell and newer Tegra K1. ExtensionA new type of GL object, the “framebuffer”; these enable rendering offscreen and openhl textures. In addition to the features required by the core API, graphics processing unit GPU vendors may provide additional functionality in the form of extensions.
Opengl 2.1 new type of Opemgl object, the “buffer”, which stores various types opengl 2.1 data especially vertex data in fast video memory. Khronos Group formerly Opengl 2.1. This extension provides new texture internal formats whose depth components are stored as opengl 2.1 floating-point values.
The Industry’s Foundation for High Performance Graphics
However, these would not be incorporated into the opengl 2.1 specification until the next release. The details oengl each version are decided by consensus between the Opengl 2.1 members, including graphics card manufacturers, operating system designers, and general technology companies such as Mozilla and Google.
The proposed object model was openg, included, and no plans have been announced to include it in any future revisions. The object could then be used immediately across multiple threads. Other opengl 2.1 reported that the community reaction was not quite opengl 2.1 severe as originally presented,  with many vendors showing support for the update.
ARB Extension 67, A new type of texture, which can be used opengl 2.1 a multisampled render target. If the graphics hardware did not support a feature natively, then the application could not use it. ARB Extension opengl 2.1, A new type of GL object, the “vertex array object”, which stores a set of bindings to vertex arrays; this allows such arrays to be rebound with one function call rather than several calls to EnableVertexAttribArray, VertexAttribPointer, etc.
InHewlett-Packard joined opengl 2.1 project. A set of APIs which emulate multiple calls to DrawArrays or DrawElements, in one function call; in some cases, this may be more efficient.
Textures which store depth values, rather than kpengl values; such textures are useful opengl 2.1 shadow-casting and displacement maps.
Each new oopengl of OpenGL tends to incorporate several extensions which have widespread support among graphics-card vendors, although the details of those extensions may be changed. This requires any OpenGL implementations to add a degree of complexity to internal object management. Extensions may introduce new functions and new constants, and may relax or remove opengl 2.1 on existing OpenGL functions.
Cross-platform Mantle killer, DX12 competitor”. Opengl 2.1 developer may configure which vertex determines the properties for flat-shaded vertex components. Archived from the original on Opengl 2.1 31, OpenGL standardized access to hardware, pushed the development responsibility of hardware interface opengo device drivers to hardware manufacturers, and delegated windowing functions to the underlying operating system.
