what is oculus Rift.?

Oculus Rift is the form of Virtual reality gaming. The Oculus Rift is an upcoming virtual reality head-mounted display. It is being developed by Oculus VR, who have raised $16 million, of which $2.4 million was raised with crowdfunding via Kickstarter.The company was founded by Palmer Luckey and the co-founders of Scaleform, and id Software cofounder John Carmack was later hired as its Chief Technology Officer. Developer kits are in the process of being shipped out.As a head-mounted display (HMD) designer at the University of Southern California Institute for Creative Technologies, Palmer Luckey earned a reputation for having the largest personal collection of HMDs in the world, and is a longtime moderator in Meant to be Seen 3D's discussion forums.

Hardware of Oculus Rift.

The first prototype of the device used a 5.6 inch screen, but after the unexpectedly successful Kickstarter, Oculus determined that the panel wasn't available in sufficient quantities, so they changed their design to use a new 7 inch screen, which makes the Rift dev kit somewhat bulkier than the first prototypes.

The new panel's pixel switching time is significantly faster, reducing latency and motion blur when turning one's head quickly. The pixel fill is also better, reducing the screen door effect and making individual pixels less noticeable. The LCD is brighter and the color depth is 24 bits per pixel. The 7 inch screen also makes the stereoscopic 3D no longer 100% overlapping, the left eye seeing extra area to the left and the right eye seeing extra area to the right. This mimics normal human vision, which does not 100% overlap either, although the overlap area is smaller on the Rift than in real life.

The field of view is more than 90 degrees horizontal (110 degrees diagonal), which is more than double the FOV of most competing devices, and is the primary strength of the device. It is intended to almost fill the wearer's entire field of view, and the real world is completely blocked out, to create a strong sense of immersion. The resolution is 1280×800 (16:10 aspect ratio), which leads to an effective of 640×800 per eye (4:5 aspect ratio). However, since the Rift does not feature a 100% overlap between the eyes, the combined horizontal resolution is effectively greater than 640. The image for each eye is shown in the panel as a pincushioned image that is then corrected by lenses in the headset, generating a spherical-mapped image for each eye. The panel's resolution is expected to be upgraded to at least 1920×1080 for the final consumer version.

Initial prototypes used a Hillcrest 3DoF head tracker that is normally 120 Hz, with a special firmware that John Carmack requested which makes it run at 250 Hz, tracker latency being vital due to the dependency of virtual reality's realism on response time. The latest version includes Oculus' new 1000 Hz Adjacent Reality Tracker that will allow for much lower latency tracking than almost any other tracker. It uses a combination of 3-axis gyros, accelerometers, and magnetometers, which make it capable of absolute (relative to earth) head orientation tracking without drift.

The weight of the headset is approximately 379 g (an increase of about 90 grams due to the increased screen size) and it does not include headphones.

The headset has a dial on each side that can be turned with a screwdriver which allows adjusting each display to be moved closer or further away from the eyes. The development kit also includes interchangeable lenses that will allow for simple dioptric correction. Adjustment for the interpupillary distance is done in software, although given its large exit pupil, this should not be a severe issue with the Rift.

The developer version Rift has DVI and HDMI input on the control box, and comes with one DVI and two HDMI cables, and a DVI to HDMI adapter.

A USB interface is used for sending tracking data to the host machine and powering the device, potentially negating the need for an external power supply. However, since its power requirements slightly exceed the rating for USB, it will come with a power adapter that can optionally be used to connect the control box to a power outlet for those computers that don't provide enough USB power.

Software of Oculus Rift.

Games and game platforms must be specifically designed to work correctly with the Oculus Rift. Oculus is producing an SDK (software development kit) to assist developers with integrating the Oculus Rift with their games. The SDK will include code, samples and documentation. According to Oculus, game integration will begin with PCs and smartphones and be followed by consoles at a later date.

Team Fortress 2 was the first game to add support for the Oculus Rift, and is currently available to play with the Oculus Rift dev kit by use of a command line option. The second title to support the Oculus Rift was the Oculus only version of "Museum of the Microstar" which was released in April 2013. Half-life 2 was the third, and Hawken is likely to be the fourth game to support the Rift; it was prominently featured in the Kickstarter, and Oculus used it to demo the Rift at the GDC. Doom 3: BFG Edition was originally going to be the first game to officially support the Oculus Rift, but after the change of tracker and the change to the 7" panel, id has not yet updated the game to support it.

The Gallery: Six Elements is the first announced game being designed specifically for the Oculus Rift and Virtual Reality, rather than adding Rift support to an existing game. This is considered important because many existing games use features that don't translate well to VR, such as a HUD, cutscenes, menus, third person sections, fast movement speeds, not being able to see one's own body, etc. It is currently on Kickstarter.

Epic Games, creators of the Unreal Engine, have announced that the engine will integrate support for the Oculus Rift. David Helgason, CEO of Unity Technologies, has announced support for the Oculus Rift with the Unity engine. John Carmack of id Software has stated that he plans to make the Oculus Rift a concurrent part of the Doom 4 development cycle to ensure that it works well with the game at launch. Star Citizen, the upcoming space role-playing simulator from Chris Roberts is being built with Oculus support.

Several prominent figures from the games industry, notably John Carmack, the co-founder of Id Software, Gabe Newell, the co-founder of Valve Corporation, Michael Abrash, the author of Zen of Graphics and Graphics Programming Black Book, Cliff Bleszinski, former design director at Epic Games, and David Helgason, the founder of Unity 3D publicly endorsed the campaign. Markus Persson, founder of Mojang, has stated that the company's games will likely support the Oculus Rift. Michael Abrash, who is researching virtual reality and augmented reality at Valve said "I personally would like to get our games running on the Rift and make it a great experience

Several titles are playae on the Rift via the free and open source Vireio Perception VR drivers.Games currently with full or partial Vireio Perception support include Left4Dead 1 and 2, Elder Scrolls V: Skyrim, Dear Esther, Portal 1 and 2, Half Life 2 and more.

Vireio Perception is the first to include the Schneider-Hicks Optical Calibration Tool (SHOCT), a software feature that makes it possible to safely calibrate the majority of stereoscopic 3D settings without having to wear an HMD through the process. Up until this time, it was difficult to calibrate settings like separation and convergence because head mounted displays are incapable of providing a reference for both views at the same time.

According to Meant to be Seen, open source developers of the Vireio Perception drivers, their current priorities include adding DX10 and DX11 support, easier to use game profiles, and solving the "time differential" flaw in the software's architecture.

While not yet released, another option for playing existing games is the VorpX driver ^[that has listed support for a wide variety of games built on DirectX versions 9 through 11. The majority of the rendering is expected to be using 2D+Depth technology, though true dual camera rendering will be available for a limited number of games.
