Saying I feel sorry for backing the pimax 8k because Google is working on a headset thats alot better that will probably release over a year after the 8k would be like saying I feel sorry about buying a gtx 1080 when that released when I knew that a 1080Ti and a new generation of graphics cards would be released later. No buyers remorse with the Pimax 8K as of yet as its going to stand as the best headset if they meet their promises for atleast a year from release.
it’s going to take a long time for that headset to come out i believe. in the mean time the pimax will do nicely!
also looking at those drawings it doesn’t look like like it has a very wide fov tbh.
Very old drawings.The concept may have changed a lot.
Can you spot the logic failure in your post ?
Let me help a little: buying a 1080 now is buying a 1080 now. Buying a Pimax 8K now is buying a Pimax 8K in the future, when most probably you could buy another maybe better headset.
It is like you buy a 1080 and you request to be delivered to your door in 6 month, when 1080Ti is already on market and afordable (this is a speculative example, because we all know what happened with cards prices due to mining).
Do not pretend that Pimax 8K exists and everything is ok.
`1. Delivery in Q2 means within the next 3 months
2. The Pimax 8k Exists very much.
Indeed even if it was q3 or q4 it is highly unlikely google will have these released let alone in a headset for purchase. Lol
The first UltraGear prototype is more than a year old and worked perfectly with Lighthouse 2.0. They said it was a first prototype, which would surely improve both optics and displays.
Unless you work for the US air force, humble mortals like us will not have access this kind of resolution this year. Maybe a good reason to go the CES 2019 thus…
Indeed & with how hard it has been to get the hardware combo to 90hz stable at hi res even more unlikely at 120hz tethered by a video cable. I am curious to see if when the wireless module releases if it can get 90hz stable with the bridgechip in the 5k/8k headsets.
I like the part where google solves the bandwidth problem by only sending a fraction of the display at once
"Deliver " and “Q2” are concepts that will never match together other than in our dreams.
You should take Pimax’s words with a large dose of uncertainty or approximation. .Eventually they will do it, but it is very unclear when and how good the final product will be.
Yes, the uncertainty applies to the quality too, and that’s the bad news.
Google’s new ultra high res, wide FoV, 120 hz VR HMD ------> for Smartphone gaming
Pimax 8K -----> for PC gaming
Google’s new ultra high res, wide FoV, 120 hz VR HMD -> Lenovo standalone, LG UltraGear VR PC Gaming.
But Pimax 8k specifications are better.
So it’s all market HTC can do a Pimax 8K but they don’t.
Pimax 8K is the best option if production quality is good.
This is the point.
We don’t know the actual LG UltraGear especifications. Pimax 8K is the best option if the LG UltraGear is worse or if Pimax arrives far before.
Technically at 4.3 inches they could use Three displays to achieve a ultra wide viewing angle shouldn’t be that hard to Create the illusion of a single display
I think Pimax could work with this company to get better refresh rates in their panels
EDIT: or the new DisplayLink DL-8020 chip. Seems capable of 4k 90Hz!
But I don’t think curved displays solve the issue of vergence accommodation. They may solve the optical issues that companies like pimax face because you could just use a curved fresnel lens across the entire screen without hybrid optics.
However we need either retinal projection, like in the Avegant Glyph or we need stacked displays like NVidia showed some time back, coupled with light field rendering.
I am not sure if multiple focal planes can be sent to current VR headset to allow us to focus differently on objects that are far vs those that are close. Perhaps with foveated rendering and eye tracking as well as dynamic depth of field this can be achieved.
From what I’ve heard lightfield rendering is extremely heavy on gpu, yes you would not need eye tracking for a lightfield display, producing lightfield displays is not widely available nor do they yet reach the resolutions needed to be close to on par with pimax yet, not can they reach near the fov of pimax. Curved displays may make for a better physical form factor and make Lens distortion an easier problem I’d guess.
Light field displays can be made today by stacking two conventional LCD panels one behind the other, Nvidia has a number of articles and videos on this. If you also offset the the two displays by a fraction of a mm then you can effectively fill in the gaps between the pixels making the display dense. SO you could have two 1440p panels one behind the other which would be good enough to hide the SDE.
EDIT: Occulus has also teased conventional displays with Spatial Light Modulators to allow a sort of faked focal planes to be displayed. May or may not work with light fields, perhaps they will talk more about it at the next event they do.
As for rendering, foveated rendering can help minimize the load. But ideally using an engine like the one OTOY is working on or the rendering engine Starbreeze just purchased will make a huge difference.
I do not think Dynamic DoF is applicable for actual eyeball “focus” on single panel VR. The distance to any object anywhere on the screen is too small to trigger focus, accept maybe for sudden changes in contrast. After all DOF in rendering is just partial blur.
I think the layered displays idea is pretty neat though and seems to be the Achilles heel for AR type devices where our eyes are constantly focusing due to the real world. Strangely I did not experience discomfort on the Hololens in a 14 foot room, maybe it requires much larger focal changes for it to become an issue.
