New journey in the mystery GPU software world has began.

@rabovitz Sky belorussian protest 🤪

[Ivan Chupakhin @grinchmanXR]

Finally tried #OculusQuest2. Given the price it really seams like a worth to buy #VR headset! Enjoyed its tracking speed, picture clarity and seamless setup procedure. 😊
As everyone, hate to have being tied to #facebook account!

[Ivan Chupakhin @grinchmanXR]

Technically, my #openXR api layer is ready. Looking for any real application build against openXR for reliability, usability and performance testing.

It's alive!!! 🤪 Hooked texture, processed texture, back to pipeline!
Geeeently 😊 #openXR #dlvr

[Ivan Chupakhin @grinchmanXR]

According #OpenXR spec, API Layers are considered as loggers, validators, metric collectors, etc...But I intend to modify render textures in my layer, interfaces allow me do that. Is it legal?)

[Ivan Chupakhin @grinchmanXR]

Am I wrong or #OpenXR group really didn't make a developer guide for creating API Layers and Extensions?
I ain't blaming them, but digging into source code of OpenXR-SDK, Lunar_overlay_ext and other samples isn't so productive though is interesting )

If you have HTC Vive Pro Eye, developing some cool stuff for it in Unity then just try out our free plugin 'Digital Lens for VR' to boost clarity of what you see! https://t.co/eMkWL1oRNO

We programmers are always left out of the cool artist memes on twitter. Not this time. We have #4styles too, and we get very upset with each other for not liking the same styles #gamedev #indiedev

[Ivan Chupakhin @grinchmanXR]

Why does adding simple text widget on a viewport in #VR make so much suffering in #UnrealEngine ? Am I so stupid or what?

[Varjo @varjodotcom]

Varjo has some real big news.

We’ll be making a product announcement at Augmented World Expo on May 29-31, 2019. Find us at booth #751 on the show floor.

#AWE2019

[Ivan Chupakhin @grinchmanXR]

Happy as child! Made a custom editor's file path picker for string property in #Unity! 🤗
Rocket science! 🙈

[Ivan Chupakhin @grinchmanXR]

We've made it! All of these 4k, 8k, whateverK pixels are now visible like as no single lens stands between display and your eyes! Participants of #AWE2019, come to check our demo at booth 615.

I'm partially agree with Mr.Luckey, especially in part of overvalued expectancies. But in general #MagicLeap is a good product, it's a one of the many number of neccessary steps towards bright future of #XR

[Palmer Luckey @PalmerLuckey]

My review of Magic Leap ML1. It focuses on a few points that have not been broadly reported or analyzed by the media.

It's seems that integrating into the rendering pipeline of #Unity3D is easier than into #UnrealEngine.
But I still love the fact that Unreal is #Cplusplus
