To setup your browser, follow these steps: Firefox Nightly and WebVR Enabler Add-on (or equivalent) This includes the Oculus Rift runtime that is required to run any VR app, plus the OculusWorldDemo app, which is useful for troubleshooting. Oculus Rift SDKĪssuming you will be using an Oculus Rift, you should download and install the Oculus Rift SDK for your system. To run WebVR apps, you will need the software setup described below. If you have a slower computer, you will get a jerky display. Something like a modern MacBook Pro 15"/17" or Mac Pro, or a Windows gaming PC should be perfect. Ideally, you should be using a high spec laptop or desktop computer with a dedicated graphics card/GPU. Therefore, computers running VR applications need to be quite powerful. A lot of data needs to be processed to keep this up. Virtual Reality hardware needs to deliver high-precision, low-latency data to deliver an acceptable user experience - the display updates need to run at 60 fps otherwise the experience will seem juddery/jerky. The main issue here is that you won't have a positional tracker, and the phone processor won't be as powerful as a desktop PC, so the experience is not quite as realistic (you won't get the same effect by turning your head, and it might be jerky.) But, as an affordable test alternative, it works ok. This was the idea behind Google Cardboard. To create something approximating the same experience, you could use a supporting browser such as Firefox for Android Nightly - try running a VR app through this, and perhaps create some sort of head apparatus to mount your phone on. The display shows two slightly offset cropped and vignetted copies of a scene side by side, one for each eye, to create a stereoscopic view for the user - essential for creating the VR illusion. A VR HMD is just a high-resolution screen with a set of eye goggles in front of it. The Oculus Rift DK2 currently retails at $350, but prices are expected to come down as more headsets appear on the market, and the technology advances.įor those of you who are not in the position to invest in a full-on VR hardware unit, there are cheaper alternatives. There are a few options available for VR HMD hardware at present, but the best/most reliable one is the Oculus Rift, which comes with a robust head-mounted display and a positional tracking camera that mounts on a tripod or monitor. Head mounted displays/positional trackers Let's first look at the hardware required for WebVR. That got me the white screen and high fan noise.In this article, we'll take you through what you need to set up your WebVR testing environment - including necessary hardware and software - and share some troubleshooting tips. If your MBP doesn't get to white screen before shutting down while attempting to boot, hold down the option key and boot into recovery disk. Previously I had tried GFXbench to test it, and it went straight back to no vertical lines at boot. It got heated up a bit but no GPU issue so far. I even plugged it into a cinema display and played HD on youtube. I then I let it cool down completely, (in fact I put it outside on the balcony.) I left it for about half an hour then switched it off by holding down the power button. If you boot and get vertical stripes > apple logo > white grey screen, let it run hot as the fans kick in block the keyboard from venting airflow or wrap the mbp closed in a blanket. I followed these steps and got a workable fix: Saw all the online action, the lawsuits etc… Hopefully apple will do a recall as it was bought by me for graphic intense tasks like video editing. I had similar non bootable problem with a MBP 17 inch (early 2011). gfxCardStatus (integrated only mode) is better in this respect so I use both and now I can say that the machine is very stable and reliable after all. After about a week of gpu-switch testing, however, I have to conclude that this solution has its drawbacks too: it works fine after shutdown (including abnormal or forced one), sleep, hibernation, but it does not prevent mbp from switching to dgpu on running graphic demanding apps such as googlemaps in browser. This saved me from frequent overheat shutdowns under blanket just to load the os (after overheat shutdown the system forcibly uses igpu but this state changes back after couple of boots so it becomes necessary to overheat again). The application runs from terminal, reportedly uses the same code as gfxCardStatus but writes the setting into NVRAM(PRAM) so machine remains switched to internal GPU on next boot(s)/wake(s). Please note that only source code is there so Xcode is requred to compile the binary. It seems that I have found more reliable or permanent software solution allowing to permanently disable discrete GPU and use mbp (mine is Mbp 8.3 17i early 2011) with broken discrete GPU (failing to boot) than gfxCardStatus 1.8-2.2.1, namely.
