'''3Glasses D2''' is a [[virtual reality]] [[head-mounted display]] released in 2015.
The '''3Glasses D2''' was a tethered [[virtual reality]] [[head-mounted display]] developed by [[3Glasses]], a Chinese VR technology company. Released in 2016, the D2 was one of the first China-developed VR headsets capable of competing with established Western brands. The device featured a 2K resolution display and 110-degree field of view, making it an affordable alternative to premium headsets like the [[HTC Vive]].<ref name="digitaltrends">{{cite web|url=https://www.digitaltrends.com/vr-headset-reviews/3glasses-d2-vanguard-edition-review/|title=3Glasses D2 Vanguard Edition Review|publisher=Digital Trends}}</ref>

=== D2 Vanguard Edition ===
The D2 Vanguard Edition was released as an upgraded version of the original D2, featuring improved specifications and broader compatibility.<ref name="androidheadlines">{{cite web|url=https://www.androidheadlines.com/2016/06/3glasses-releases-d2-vanguard-edition-2k-vr-headset.html|title=3Glasses Releases D2 Vanguard Edition 2K VR Headset|publisher=Android Headlines}}</ref>
 
=== US Market Entry ===
3Glasses brought the D2 to the United States market, making it one of the first Chinese-developed VR headsets to officially launch in Western markets.<ref name="pocketnow">{{cite web|url=https://pocketnow.com/china-vr-specialist-3glasses-2k-goggles-us-launch|title=China-based VR specialist 3Glasses brings 2K goggles to the US|publisher=Pocketnow}}</ref>
 
== Design and Hardware ==
 
=== Display System ===
The D2 featured a 5.5-inch TFT-LCD display with notable specifications:
* '''Resolution:''' 2560 x 1440 (2K)
* '''Pixel Density:''' 534 PPI
* '''Refresh Rate:''' 60 Hz
* '''Latency:''' Screen response time less than 13ms
 
=== Field of View ===
The headset offered a 110-degree field of view, comparable to the [[HTC Vive]], providing an immersive viewing experience.
 
=== Optical System ===
The D2 used double non-spherical lenses with special coatings:
* Anti-blue light coating for reduced eye strain
* Anti-fogging treatment
* Adjustable to user's sight
* Compatible with eyeglasses
 
=== Weight ===
At approximately 246 grams, the D2 was notably lightweight for a tethered VR headset of its era.
 
== Tracking ==
 
The D2 utilized 3DoF (three degrees of freedom) tracking, detecting head rotation but not positional movement. This was a known limitation compared to 6DoF tracking systems like the HTC Vive's Lighthouse.
 
== Controls ==
 
The headset included:
* Touch field on the side panel
* Multiple control buttons
* Compatible with third-party motion controllers
 
== Connectivity ==
 
=== Video Connection ===
* DisplayPort 1.2 or higher
 
=== Data Connection ===
* USB 2.0 or higher
 
== Software Platform ==
 
=== SDK Compatibility ===
The D2 was compatible with:
* 3Glasses proprietary SDK
* [[Oculus Rift]] DK1 SDK (enabling compatibility with some Oculus content)
 
=== VRSHOW Platform ===
3Glasses developed its proprietary content platform called VRSHOW, providing native content for the D2.
 
== System Requirements ==
 
=== Recommended Specifications ===

== Limitations ==
 
=== No Positional Tracking ===
The D2's 3DoF tracking could not determine the user's position in a room, limiting room-scale VR experiences.
 
=== Display Technology ===
The TFT-LCD screen, while offering high resolution, had higher persistence compared to AMOLED displays, which could affect image clarity during rapid movement.
