It was first shown at the LinuxWorld Expo. Although Apple threatened to sue Sun for breach of intellectual-property rights, other window managers have implemented some of the functionality in Looking Glass. By development was discontinued by Sun, whose primary business was transitioning from graphically oriented Unix workstations to selling enterprise mainframes. Implementing compositing under the X Window System required some redesign, which took place incrementally.
In compositing, 3D effects could be applied on windows to provide 3D desktop effects. Modern compositing window managers use 3D hardware acceleration. Compositing window manager software communicates with graphics hardware via programming interfaces such as OpenGL or Direct3D. The earliest widespread implementations using this technique were released for the Mac in Mac OS X OpenGL is still not fully supported in hardware, so performance of OpenGL-based compositing should continue to improve as hardware improves [ citation needed ].
Stacking window managers running on X server required a chroma keying or green screening extension. Compositing was introduced by way of the "Composite" extension. Compositing managers use hardware acceleration through this extension, if available. Under Linux and UNIX, the ability to do full 3D-accelerated compositing required fundamental changes to X11 in order to use hardware acceleration.
Originally, a number of modified X11 implementations designed around OpenGL began to appear, including Xgl. The introduction of AIGLX would eliminate the need to use Xgl, and allow window managers to do 3D accelerated compositing on a standard X server, while still allowing for direct rendering. Compiz introduced a cube effect, which allows the user to see up to 6 virtual desktops at once.

Each desktop is converted into a surface texture of the cube, which can be rotated at will. Compiz displays a wide array of 2D and 3D effects and has relatively low hardware requirements. It uses the display engine Clutter, which has been ported to all major operating systems, netbooks and smartphones. KWin features much of the same functionality also present in Compiz. Project Looking Glass was a window manager combining 3D rendering and the cross-platform Java programming language.
In the aftermath of it being discontinued, some of its features, such as cover switching and thumbnail live previews, have found their way onto other window managers. Its more original features included window tilting, two-sided window frames and parallax scrolling backgrounds.
As such, their window managers have mostly planar rendering capabilities that include composite layering, alpha blending, gradients, high resolution and multiple desktops "screens" that can partially clip one another. While the window manager in Windows does perform compositing, it does not perform transformations such as a per-pixel alpha.

Few commercial applications took advantage of alpha blending; freeware programs were among the first to experiment with it, albeit through optional settings. In addition, it is automatically disabled by Windows in order to perform hardware overlay through the Overlay Mixer Filter. The compositing approach makes it easier to implement a number of features that make the user interface more accessible, simpler to use or with eye candy elements. Vector graphics , such as TrueType fonts and 3D-accelerated elements, can be expanded without degradation usually due to aliasing.
A screen magnifier enlarges an area of the screen, making portions of text easier to read — whether to prevent eye strain , for the visually impaired , or simply at a distance. Zoom effects such as the fish eye magnifier and zoom desktop effects provide this functionality. A preview of a window can be displayed in a pop-up thumbnail when the user hovers its associated taskbar button. This allows the user to identify and manage several concurrently running programs.
Windows with similar names and icons tend to cause confusion, especially when their title bars overlap; the position of every such window on the taskbar has to be memorized. When there are many open windows in this manner, the user often has to resort to trial and error—clicking each taskbar button one-by-one—before proceeding. Window switching allows one to quickly preview several windows at once by temporarily rearranging them against a decorative background.
After a selection is made, the windows are then restored to their original arrangement.
What Are Tiling Window Managers?
Selection begins when the user either enters a hotkey combination , moves the mouse pointer to a hotspot on the screen , or, in some situations, uses the mouse's scroll wheel. Items are navigated using the keyboard or mouse. An item is selected by either releasing the hotkey, hitting the Enter key or clicking on it with the mouse.

The flip switcher is an enhancement to the Alt-Tab switching feature. Running windows are arranged into a stack — similar to a flip-style selector in a s jukebox , or a Rolodex. In some systems, the user can press Alt-Shift-Tab to navigate backwards. Visual transitions are applied to each item while navigating. Cover switching is like flip switching with a few, mostly visual, differences.
Instead of one stack with the selection at the top, two symmetrical stacks are shown with the current selection front and center similar to the window tilting feature in Looking Glass. Cover Flow is an implementation of cover switching in macOS. More recent versions use blurring to de-emphasize non-selected items. Cover Flow has also been implemented in other software published by Apple such as iTunes.
Ring switching is like flip switching, except the windows move in a circle, with the current selection in front, usually at the bottom.
If you are a well aware Linux follower for last 4 years, you might have heard of Pear OS. This was simply MacOS of Linux world. It has a logo of a bitten pear. But 3 years back, Pear OS suddenly announced its demise. It is clearly inspired by MacOS. The bottom plank is not the only thing that you can relate to MacOS. Look at the Geary, Photos, Scratch and other apps.
They have a Mac feel despite being so elementary-ish. Do keep in mind that they are not just putting a MacOS looking theme on the top of Ubuntu. They are doing some serious work to give the entire OS an elementary feel. If you want a Linux that has a Mac feel but provides a great community support, elementary OS should be the first choice.enter site

Deepin Linux was initially based on Ubuntu but it now uses Debian as its base. They have created their own desktop environment along with a range of other Deepin specific applications that blend perfectly to give you an aesthetic feel. As you can see in the video above, Deepin Linux is undoubtedly one of the most beautiful Linux distribution ever. The Deepin team is based in China and their primary target is Chinese audience and hence some of their applications are not available in other languages. This is an area where they can certainly improve. BackSlash Linux is relatively new and relatively unknown entrant in the Linux distribution world.
It is based on Ubuntu and follows a release cycle similar to Ubuntu. While it is available for a free download, you also have the option to buy support. Unlike the above mentioned MacOS look alike Linux distributions, Gmac is not a full-fledged distribution. Gmac already does it for you. Plus you get to keep your Ubuntu distribution. There is not enough information available about Trenta OS at this time. Focus has been kept on the looks and UI. Terminal and some other regular applications are also tweaked to make it look like MacOS.
You can also watch it on GitHub. Puppy Linux is one of the best lightweight Linux distributions for older computers. There is one problem with it, though. In a few months, the support for this version would end.
