28-513: KDE Plasma (Beginning with 20.10) Ubuntu Studio is a recognized flavor of the Ubuntu Linux distribution , which is geared to general multimedia production. The original version, based on Ubuntu 7.04, was released on 10 May 2007. The real-time kernel , first included with Ubuntu Studio 8.04, was modified for intensive audio, video or graphics work. The 8.10 Ubuntu Studio release lacks this real-time kernel. It has been reimplemented in

56-404: A graphics processing unit (GPU). It is designed for embedded systems like smartphones , tablet computers , video game consoles and PDAs . OpenGL ES is the "most widely deployed 3D graphics API in history". The API is cross-language and multi-platform . The GLU library and the original GLUT are not available for OpenGL ES, freeglut however, supports it. OpenGL ES is managed by

84-530: A convergent graphical shell, which can adjust itself according to the device in use. 5.0 also includes a new default theme, dubbed Breeze. Qt 5's QtQuick 2 uses a hardware-accelerated OpenGL( ES ) scene graph (canvas) to compose and render graphics on the screen, which allows for the offloading of computationally expensive graphics rendering tasks onto the GPU, freeing up resources on the system's main CPU. KDE Plasma 5 uses

112-407: A lightweight interface, including: The actual version is 1.0.0.2. OpenGL ES 1.1 added features such as mandatory support for multitexture, better multitexture support (including combiners and dot product texture operations), automatic mipmap generation, vertex buffer objects , state queries, user clip planes, and greater control over point rendering. Actual Version is 1.1.12. OpenGL ES 2.0

140-418: A much wider range of software. In the past there has been no live version available of Ubuntu Studio, and no graphical installer. Since the 12.04 release, Ubuntu Studio has been available as a Live DVD. The disk image is about 1.8 GB, too large to fit on a standard CD , and as a result the recommended installation medium for Ubuntu Studio is a DVD or USB flash drive . Ubuntu Studio can also be installed on

168-421: A new default theme, "Breeze", and increased convergence across different devices. The graphical interface was fully migrated to QML , which uses OpenGL for hardware acceleration, providing better performance and reduced power consumption. Plasma Mobile is a Plasma 5 variant for Linux-based smartphones. KDE Plasma 5 is built using Qt 5 and KDE Frameworks 5. It improves support for HiDPI displays and ships

196-506: A pre-existing Ubuntu installation by installing the "ubuntustudio-desktop" package from Advanced Packaging Tool . In 9.10, the package "ubuntustudio-audio," shown during installation (and also available in the Synaptic Package Manager), cannot be installed without a working Internet connection. An Internet connection is required after installation to maintain system components. KDE Plasma 5 Plasma 5 includes

224-432: A smaller memory bandwidth footprint, floating point render targets for high accuracy compute processes, and new debugging features for developers. These high-end features are already found in the group’s full OpenGL 4 specification." Supported by Windows, Linux, Android (since version 6.0 possible, 7.0+ Vulkan 1.0 and OpenGL ES 3.2 needed) on devices with appropriate hardware and drivers, including: OpenGL ES (and OpenGL)

252-459: Is 2.0.25. The Khronos Group has written a document describing the differences between OpenGL ES 2.0 and ordinary OpenGL 2.0. The OpenGL ES 3.0 specification was publicly released in August 2012. It is backwards compatible with OpenGL ES 2.0, and partially compatible with WebGL 2.0, as WebGL 2.0 was designed to have a high degree of interoperability with OpenGL ES 3.0. The current version of

280-641: Is 3.1-(November 2016). The OpenGL ES 3.2 specification was publicly released in August 2015. New capabilities in OpenGL ES 3.2 include: Actual State is 3.2.6 July 2019. OES_viewport_array Some more extensions are developed or in Development in Mesa for next OpenGL ES Version (see Mesamatrix). Next generation API is Vulkan. For complete list of companies and their conformant products, view here OpenGL ES 1.0 added an official 3D graphics API to

308-450: Is a set of OpenGL ES 3.1 extensions, all bundled into a single extension introduced by Google in 2014. This allows applications to use all of the features of the set of extensions, while only testing for the presence of a single one. The AEP was officially added to Android Lollipop to provide extra features like tessellation over what was officially in the GLES 3.1 revision. OpenGL ES 3.2 update

336-551: Is largely made up of the AEP additions, which are already present in desktop OpenGL. OpenGL ES 3.2, incorporating the Android Extension Pack (AEP), "boasts a small number of improvements over last year’s OpenGL ES 3.1. Both make use of similar features from the AEP. From the AEP, OpenGL ES 3.2 compliant hardware will support Tessellation for additional geometry detail, new geometry shaders, ASTC texture compression for

364-638: Is on its own release schedule, with feature releases every four months, and bugfix releases in the intervening months. The latest Plasma 5 features the following workspaces: The first Technology Preview of Plasma 5 (at that time called Plasma 2 ) was released on 13 December 2013. On 15 July 2014, the first release version – Plasma 5.0 – was released. In spring 2015, Plasma 5 replaced Plasma 4 in many popular distributions, such as Fedora 22, Kubuntu 15.04, and openSUSE Tumbleweed. Feature releases are released every four months (up to 5.8 every three months) and bugfix releases in

392-729: The Android and Symbian OS v8.0a operating systems, as well as by QNX It is also supported by the PlayStation 3 as one of its official graphics APIs (the other one being low level libgcm library) with Nvidia's Cg in lieu of GLSL. The PlayStation 3 also includes several features of the 2.0 version of OpenGL ES. The 1.1 version of OpenGL ES is supported by: Supported by: Supported by: Supported by some recent versions of these GPUs: Supported by Windows, Linux, Android (since version 5.0) on devices with appropriate hardware and drivers, including: Android Extension Pack (AEP)

420-614: The X Window System and Wayland . Support for Wayland was prepared in the compositor and planned for a later release. It was made initially available in the 5.4 release. Stable support for a basic Wayland session was provided in the 5.5 release (December 2015). Support for NVIDIA proprietary driver for Plasma on Wayland was added in the 5.16 release (June 2019). Since the split of the KDE Software Compilation into KDE Plasma, KDE Frameworks and KDE Applications, each subproject can develop at its own pace. KDE Plasma 5

448-466: The non-profit technology consortium Khronos Group . Vulkan , a next-generation API from Khronos, is made for simpler high performance drivers for mobile and desktop devices. Several versions of the OpenGL ES specification now exist. OpenGL ES 1.0 is drawn up against the OpenGL 1.3 specification, OpenGL ES 1.1 is defined relative to the OpenGL 1.5 specification and OpenGL ES 2.0 is defined relative to

476-563: The 9.04 Ubuntu Studio release and stabilized with the release of 9.10. 10.04 Ubuntu Studio, in contrast, does not include the real-time kernel by default. As of version 10.10 of the Ubuntu Studio, the real-time kernel is no longer available in the repositories. As of Ubuntu Studio 12.04, the default kernel is linux-lowlatency, which in essence is a generic Ubuntu Linux kernel, with a tweaked configuration to allow for stable operation for audio applications at lower latencies . Since much of

504-531: The OpenGL 2.0 specification. This means that, for example, an application written for OpenGL ES 1.0 should be easily portable to the desktop OpenGL 1.3; as the OpenGL ES is a stripped-down version of the API, the reverse may or may not be true, depending on the particular features used. OpenGL ES comes with its own version of shading language (OpenGL ES SL), which is different from OpenGL SL . Version 1.0 and 1.1 both have common (CM) and common lite (CL) profiles,

532-508: The OpenGL ES 3.0 standard is 3.0.6, released in November 2019. New functionality in the OpenGL ES 3.0 specification includes: The OpenGL ES 3.1 specification was publicly released in March 2014. New functionality in OpenGL ES 3.1 includes: OpenGL ES 3.1 is backward compatible with OpenGL ES 2.0 and 3.0, thus enabling applications to incrementally incorporate new features. Actual Version

560-490: The advanced desktop effects can be enabled. More advanced Compiz effects are available in the Synaptic Package Manager (i.e., Ubuntu repositories). In Karmic 9.10, a fresh sound theme replaces the default Ubuntu theme, with a reverberating melody at startup, and an occasional knock or ping from a button or prompt. Xfce (instead of GNOME) was the default user interface until v20.04. From Ubuntu Studio 20.10,

588-602: The default user interface became KDE. An important advantage of Ubuntu Studio over most other Linux distributions employing the real-time kernel is access to the same repositories available to the main Ubuntu distributions through the Update Manager, Synaptic Package Manager, as well as through the Add/Remove Applications prompt. This allows for much more frequent operating system updates, and access to

616-404: The difference being that the common lite profile only supports fixed-point instead of floating point data type support, whereas common supports both. OpenGL ES 1.0 was released publicly July 28, 2003. OpenGL ES 1.0 is based on the original OpenGL 1.3 API, with much functionality removed and a little bit added. One significant difference between OpenGL and OpenGL ES is that OpenGL ES removed

644-531: The intervening months. Following version 5.8 LTS KDE plans to support each new LTS version for 18 months with bug fixes, while new regular releases will see feature improvements. OpenGL ES 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

672-509: The need to bracket OpenGL library calls with glBegin and glEnd . Other significant differences are that the calling semantics for primitive rendering functions were changed in favor of vertex arrays, and fixed-point data types were introduced for vertex coordinates. Attributes were also added to better support the computational abilities of embedded processors, which often lack a floating point unit (FPU). Many other functions and rendering primitives were removed in version 1.0 to produce

700-427: The real-time patch has now been implemented into the vanilla kernel, and considering the difficulties in maintaining linux-rt, Ubuntu Studio decided on using linux-lowlatency in its place. The scheduler allows applications to request immediate CPU time, which can drastically reduce audio latency . In 9.10, the "Ubuntu Studio Controls" provided under System>Administration permit the user to "Enable Nice", allowing

728-530: The transform and lighting stage, such as the specification of materials and light parameters formerly specified by the fixed-function API, are replaced by shaders written by the graphics programmer. As a result, OpenGL ES 2.0 is not backward compatible with OpenGL ES 1.1. Some incompatibilities between the desktop version of OpenGL and OpenGL ES 2.0 persisted until OpenGL 4.1, which added the GL_ARB_ES2_compatibility extension. Actual version

756-523: The use of wireless networking and proprietary graphics cards drivers while maintaining low audio latency free of XRUNs (audio drop-outs) in JACK . A more negative value entered for nice reserves more CPU time for real-time audio processes. Ubuntu Studio also includes custom artwork and a blue-on-black theme, as opposed to Ubuntu's default purple and orange. As with the main distribution of Ubuntu, if an accelerated graphics card and appropriate driver are used,

784-424: Was publicly released in March 2007. It is roughly based on OpenGL 2.0, but it eliminates most of the fixed-function rendering pipeline in favor of a programmable one in a move similar to the transition from OpenGL 3.0 to 3.1. Control flow in shaders is generally limited to forward branching and to loops where the maximum number of iterations can easily be determined at compile time. Almost all rendering features of
