In the past few weeks I have repeatedly reported on new China virtual reality headsets, which have been on the rise since 2016 and may even form a popular niche for “branded VR”. A very interesting China VR glasses come from the manufacturer 3Glasses, which sells a VR headset called the "3Glasses D2 Vanguard", which, similar to the Oculus Rift, has its own SDK and is also connected to the PC via HDMI.
3Glasses D2 Vanguard
The 3Glasses D2 there are so far very few information in the network, let alone reviews or reviews. Only on YouTube is a brief hands-on VR headset, but to what extent the 3Glasses D2 actually with current VR as the Oculus Rift or HTC Vive is comparable, can only guess.
The manufacturer's website is surprisingly available in English. Some information about the D2 Vanguard can be found here. The Virtual Reality Headset D2 has a 5.5 inch display with a resolution of 2K (2560x1440). The dot density is 534 PPI. According to the FAQ on the website, this is a TFT screen. The disadvantage of a TFT display, however, is that the image "drags" a bit and the colors and the black level will not be too strong. One can only hope that 3Glasses will use a high-quality AMOLED display in subsequent models.
With a field of view (FOV) of 110 °, the D2 is based on an HTC Vive. The refresh rate, on the other hand, is only 60 Hertz, the delay, however, is given a fairly solid value of <13 milliseconds. The lenses are double, non-spherical lenses. The 3Glasses D2 can also be used with low myopia. To achieve accurate head tracking, the 3Glasses D2 has an integrated inertial measurement unit (IMU). This is a combination of acceleration sensors and yaw rate sensors that precisely record head movements. What this headset lacks, however, is the ability to determine the position in the room.
The VR headset is connected via HDMI. The device also has a USB 2.0 socket. It is operated via a touch field on the side and several control buttons. With a weight of around 246g, the D2 is comparatively light, which, in combination with the 3-point head strap, should be comfortable to wear.
A very interesting feature is the compatibility of the D2 Vanguard with the Oculus Rift DK1 SDK. In addition, the VR glasses also have their own SDK, which gives developers a lot of leeway. However, it is not compatible with the Oculus Rift DK2 SDK or even runtime.
The D2 has been available since March 2016 and can be ordered via the manufacturer's official website. Alternatively, this VR headset is also available from various online shops, such as “Gearbest”. There are no reviews of the 3Glasses D2 yet.
