The Khronos Group - a non-profit industry consortium to develop, publish and promote open standard, royalty-free media authoring and acceleration standards for desktop and handheld devices, combined with conformance qualification programs for platform and device interoperability.
Khronos Group 是由其成员所提供之基金支持的行业协会，专注于创立开放标准，免授权费的移动设备接口程序API, 用以实现多样化平台及设备上的高质量动态多媒体创作和加速。所有的Khronos工作组成员均可为Khronos API规范的制定贡献其力量，均可在相关标准公开部署前拥有各个发展阶段的表决权，更可通过及早接触相关标准草案及顺应性测试加速其先进的3D平台及相关应用程序的发布。
OpenGL® ES 是免授权费的，跨平台的，功能完善的2D和3D图形应用程序接口API，它针对多种嵌入式系统专门设计 - 包括控制台、移动电话、手持设备、家电设备和汽车。它由精心定义的桌面OpenGL子集组成，创造了软件与图形加速间灵活强大的底层交互接口。OpenGL ES 包含浮点运算和定点运算系统描述以及 EGL™ 针对便携设备的本地视窗系统规范。OpenGL ES 1.X 面向功能固定的硬件所设计并提供加速支持、图形质量及性能标准。OpenGL ES 2.X 则提供包括遮盖器技术在内的全可编程3D图形算法。OpenGL ES-SC 专为有高安全性需求的特殊市场精心打造。
WebGL 是免授权费的，跨平台的应用程序接口API，它将OpenGL ES 2.0作为在HTML网页内的3D绘图环境，作为低级别文档对象模型接口开放。它使用OpenGL渲染语言GLSL ES，并可被整洁地与其他3D内容上层或下层的网页内容捆绑。它是使用JavaScript编程开发语言开发适合动态3D网页应用的理想工具，并已被主流互联网浏览器集成。
WebCL - Heterogeneous parallel computing in HTML5 web browsers
The WebCL working group is working to define a JavaScript binding to the Khronos OpenCL standard for heterogeneous parallel computing. WebCL will enable web applications to harness GPU and multi-core CPU parallel processing from within a Web browser, enabling significant acceleration of applications such as image and video processing and advanced physics for WebGL games. WebCL is being developed in close cooperation with the Web community and has the potential to extend the capabilities of HTML5 browsers to accelerate computationally intensive and rich visual computing applications.
COLLADA - 交互3D数字资产交换方案
COLLADA™ 是面向交互式 3D 应用程序的基于 XML 的数字资产交换方案，使 3D 创作应用程序可以自由地交换数字资产而不损失信息 - 使多种DCC和3D处理软件包可以组合成强大的工具链管道。独特的交互模式提供了广泛全面的视觉编译。COLLADA FX支持使用 OpenGL ES 着色语言创作和封装着色器，以使一流的 3D 创作工具可以有效协作创建 OpenGL / OpenGL ES 应用程序和资产。
StreamInput - Cross-platform advanced sensor processing and user interaction
The Khronos StreamInput working group is driving industry consensus to create a cross-platform API to enable applications to discover and use new generation sensors to create sophisticated user interactions. The new API will support a general-purpose framework for consistently handling advanced sensors such as depth cameras, touch screens and motion and orientation sensors as well as traditional input devices. StreamInput will provide flexible device discovery to enable an application to select and process high-level semantic input from low-level device capabilities, enabling significant innovations by sensor and device manufacturers while simplifying portable application development. The API will also provide system-wide sensor synchronization for advanced multi-sensor applications such as augmented reality, and will use Khronos’ proven extension mechanisms to enable new types of input devices to be easily added and supported.
Forums: The best place to obtain fast technical support for any API development & coding questions. The forums are frequented by all of the API development engineers and architects.
Khronos API Registry contains specifications, header files, extension specifications, enumerant and function registries, and other related documentation for Khronos APIs.
Khronos Bugzilla is the public bug tracker and ideal if you feel you have found a bug in one of the API's.
Khronos Developer Resources provides documentation, specifications, tutorials and sample code for all public Khronos technologies.
OpenGL Extension Registry is maintained by Khronos and contains specifications for all known extensions, written as modifications to the appropriate specification documents. The registry also defines naming conventions, guidelines for creating new extensions and writing suitable extension specifications, and other related documentation.
OpenGL SDK is a gathering of 3rd party contributions from many of the leaders in the community. Some information and downloads are available directly from the SDK and some information and downloads you'll find links to the original materials elsewhere on the web. In all cases, the contributions have been hand selected and represent the best of what's out there.
