spite / webvr-extension Goto Github PK

OK, I'm going to take a swing at this and lets see what you think.

There is an algorithm that is used to modify the screen so that the human eye can focus when a phone is held up close and viewed through lenses. You can see what the algorithm is suppose to do to the screen output at the 15 seconds point of this video when the little cardboard icon is clicked:

https://youtu.be/D8dj0bk3cWQ?t=13s

I don't know if that algorithm is actually used with this browser extension or if you're just calling some API function provided by chrome or android or whatever, but if you are or know of how to find that function, as in you could literally copy and paste the math into another file and it would have no additional dependencies left behind... then I would like your help in the idea of applying that algorithm to the entire Android operating system... the idea being you would use your phone with the VR goggle, be able to still visually use your operating system but now using a wireless keyboard and mouse (OTG cables work too)... this would be so empowering where, for very cheaply (I found the goggle, keyboard and mouse on ebay for like $30), just about anybody could immerse themselves in a different environment on demand (especially with ear buds if you're in public spaces or trying to work on code or study an article for school and want 100%)... as of Android 5.0 you can easily invert the screen colors so that reading text is much easier... there's got to be a way to update the older phones, obviously not for things they physically do not have (they do have a cpu that can do the math operations to split the screen) like the gyroscope features where your headset moves around if you twist your neck.

I have no idea if this is the correct direction as my area of focus for software development has been chrome extensions and JavaScript stuff, but I was sniffing around the android domains and think I've found this as a thing to look into, https://source.android.com/devices/graphics/arch-bq-gralloc of course, if someone who actually knew what they were talking about when it comes to android was reading this message, they could probably maneuver the copy/paste of that algorithm relatively easily I'd imagine. Oh, and I'm certain this is a general purpose algorithm in the sense I've been referring to since the same thing is also applied to youtube as well as video games according to the google daydream advertisements.

So, any comments? Know of anybody who might know of someone who would know how to do this?

Hello,

Recently, I have some errors with the WebVR Chrome extention to view the vr examples on threejs.com like the basic one > threejs.com cubes example

When I click on "ENTER VR", I have an error wich says
VM396:240 Uncaught ReferenceError: currentLayers is not defined

So the VREffect cannot display the dual view.
I suppose it is linked to the recent changes #19 because I didn't have this error a few days ago.

Do you have the same problem?
Thank you

• Intercept Gamepad API and inject poses from extension
• Add UX/UI to represent controllers, select them, and work with them

Potential solution: #4

From work on https://github.com/spite/WebVR-Recorder it might not be trivial to inject into the Gamepad API, since GamepadPose is read-only.

Hi, this is not critical issue but got confused by cuboid movements in webvr extension tab in web tools. I can see that cuboid turn around axes X and Z swaped with how turn appears to take place on the screen. While there no indication which angle is which in extension that may mean that turn is correct but visually still thinking of cuboid movement. I checked this on webvr examples and sketchfab models, currently just ignoring cuboid visual movement and accept turns as correct if they are same in examples present.

• Add dispatching of vrdisplayactivate and vrdisplaydeactivate events
• Add UX/UI to activate and deactivate HMD

Add support to use this extension in Firefox.

After mrdoob/three.js#14743 we no longer see the stereo view because an additional render is now done when the system has a external display.

Was the plan to have a dropdown and be able to select one of these?

Hi, seems buttons and inscriptions moving with window borders may make messy view sometimes.

Thanks for this extension :)
Any idea why this extension doesn't work on Shadertoy with VR shaders?
E.g. if I go to https://www.shadertoy.com/view/llj3Rz and click on the VR button, it says

WebVR API is not supported in this browser

But it works on this site:
https://webvr.info/samples/05-room-scale.html

Instead of replacing the API completely, try to build on top of it and add Emulated devices.

VRDisplayEvent received when onvrdisplaypresentchange is triggered should have a display property pointing on the VRDisplay instance.

From the spec

interface VRDisplayEvent : Event {
  readonly attribute VRDisplay display;
  readonly attribute VRDisplayEventReason? reason;
};

This would be a great addition. Thanks.

Add UX/UI to edit VRStageParameters.sittingToStandingTransform.

I'm absolutely sure that this is covered by #21, though I thought it might be useful to log a specific example of Origin Trial issues.

When viewing a page with an active webvr origin-trial, I get the following error:

TypeError: Cannot assign to read only property 'pose' of object '#<VRFrameData>'

It looks like I'm passing a native VRFrameData object which has a readonly pose attribute

Hi @spite,

First off, fantastic work! I hope I'm not stepping on your toes, but I was considering adding an emulated HTC Vive controller in a fashion similar to your monkey-patching of navigator.getVRDisplays. Initially just something simple in terms of being able to position/orient it in space and depress buttons. Should I get something functional in a PR in order to discuss further?

Thanks,

• Add support to modify stageParameters sizeX and sizeY
• Add UX/UI to modify those values

From the new spec, and this https://github.com/w3c/webvr/blob/gh-pages/js/webvr-1-1.js

Enable and complete renaming of poses

webvr.info recently implemented Origin Trials, so the WebVR API is available for the page.

One side-effect of that is that, since the API is "loaded" when the page loads and the OriginTrials token is processed, it overwrites with native methods what the emulator has injected from the content-script, creating a mess of native and injected methods.

Any plans to support WebXR in this extension or to make another extension WebXR-Extension?

Return an array of VRLayer (TBD)

I'm not sure if this is intended or it went unnoticed, but starting with a fresh reset position the orientation reads [0,0,1,0] in the GUI but [0,0,0,1] in the console using this code
var orientation = frameData.pose.orientation; console.log(orientation);
The WebVR spec says it should be [0,0,0,1] but somehow the GUI gets it wrong. I noticed this problem when wanting to use the individual values in a webgl lookat function trying to read orientation[2] instead of orientation[3] because of the GUI.
