Testing the eDrawings Virtual Reality Prototype with Google Cardboard

In the Partner Pavilion at SolidWorks World 2016, the mobile products team demonstrated a prototype of the eDrawings mobile app, with support for Virtual Reality via Google Cardboard.

Cardboard is an inexpensive, open source virtual reality viewer, meant to be used with apps on your phone. An alternative to expensive VR rigs like the Occulus, Cardboard uses the high-quality graphics, accelerometers, and processing power already in your pocket. Inexpensive Cardboard headsets are available available from many outlets, such as this one from Amazon.

The eDrawings team has worked quickly to integrate this technology into their product, and were able to demonstrate a functional prototype at SolidWorks World 2016. The prototype was hosted on an iPhone 6 Plus, but the team assured me that iOS and Android versions are being developed in parallel.

Viewing a model in eDrawings virtual reality allows you to add an extra layer of immersive realism to your design, using the movement of your head, rather than your finger, to manipulate the model.

Similar to other Cardboard apps, the VR function of eDrawings mobile generates two images of the object being viewed, with a slight offset to account for stereo vision, making the object appear three-dimensional. Convex lenses in the Cardboard headset resolve the two images into one, and make it appear farther than a few inches in front of your eyes. The accelerometers in the phone also track movement, so the object moves and rotates, changing your perspective as you move your head.

 

As a prototype, the new eDrawings VR mode I tested was certainly unpolished, but the basic functions – stereo imaging, head tracking, etc. – were implemented well. However, more functions will need to be added to make VR viable, rather than foregoing the goofy-looking box and simply using your finger.

If all goes well, the team hopes to release the VR feature update sometime this year (possibly alongside the release of SolidWorks 2017). Be sure to stop by the SolidWorks area in the center of the Partner Pavilion at SolidWorks World 2016, to try out the Cardboard prototype, along with a bunch of other great projects now under development.
