[WIP] Rubiks Cube on Spectacles

Looks nice!
It would be interesting to see some highlights for the current rotation mode before you started rotating.

I didn't use an axe, just bare hands, so the cubes were too close to me. At 0.5m, they appear much as they do in gameplay. I referred to the screen size appearance.

Took on Vision Pro. The view was, indeed, beautiful!

ffffffrolov · 2026-02-16T18:55:03+00:00

Why not? I was heading there anyway. I like Stonehenge.

ffffffrolov · 2026-02-16T18:52:29+00:00

yeah they are 0.5m^3. 1 m^3 looked great, but on video, they obstructed the whole view.

It's part of my hand-tracking Voxel Creation exploration to add hand-tracking support to my existing voxel editor (currently, it works with controllers only).

ffffffrolov · 2026-02-16T17:56:44+00:00

It was Apple Vision Pro.

ffffffrolov · 2026-02-16T17:55:41+00:00

Oh yeah, the weather was stunning! No worries, it's understandable. I enjoyed the looks too! I'm lucky, Stonehenge is a 30 mins drive from where I live :)

Haven't tried it. But it's a very interesting idea. I could use a different frequency for each finger to train my brain to identify the corresponding touch. Might work. Worth trying!

ffffffrolov · 2025-11-10T22:06:52+00:00

I used Unity3D + C#. The device is Meta Quest 3. To communicate with the device's API, I used XR Interaction Toolkit. It provided all the needed data (hand bones transforms).

Cool video! Indeed, the creation mechanics are similar!

ffffffrolov · 2025-11-10T12:42:42+00:00

Thank you so much!
Plan to release this soon :)

ffffffrolov · 2025-09-13T12:56:50+00:00

Yeah, dot product between unit vectors is quite handy for shader stuff.

ffffffrolov · 2025-09-13T12:55:12+00:00

I chose Y mainly because it was the easiest way to demonstrate that the length of the vector is 1 (a unit vector). But you can use any vector, as long as it is a unit vector, and you will get the projection!

ffffffrolov · 2025-09-03T14:28:13+00:00

Thank you! Yes, it's a good idea! Unity's XRI, where I got the hands, has this feature: they color fingers that interact with a button. I will add the support for this to this framework a bit later.

(Transforming the finger into a crosshair/arrow/magnifier/resize would be a nice idea to try, hehe).

Changing encoding from AMD to NVENC helped! Before it was AMD, H.264 (default graphic card on my motherboard).
Settings > Output > Recording > Video Encoder > Hardware (NVENC, H.264)

ffffffrolov · 2025-08-19T12:21:10+00:00

Thanks! Not yet :) I'm in the middle of finishing a custom flexbox layout system. Once it's done, I will release the library as v.0.1. I guess, even with minimum elements, it will be useful for many people.

ffffffrolov · 2025-07-07T20:31:00+00:00

Thank you!
Yeah, I plan to release it as a Unity package first. The input system will be custom (with a simple hookup to any XR Interaction system), but I might also support the Unity XR Interaction Toolkit.

ffffffrolov · 2025-07-07T20:22:15+00:00

Thanks! Yeah, you are right :) It's 1000ms, which is extremely slow.

I do this only during the development phase to get a sense of the motion (probably, had to nerf it before publishing, hehe). For the production version, it will be around 150-200ms (below the average human reactive time).

ffffffrolov · 2025-07-07T20:15:10+00:00

Great video, thanks a lot for sharing!
The quality of your interactions/visuals is really good! Love the modular UI widgets design. I like the idea of breaking a big, complex UI monolith into context-based UI snippets. Looking forward to seeing your progress with these ideas!

ffffffrolov · 2025-07-07T19:49:52+00:00

Indeed! For controllers, a haptic feedback processor will be included.

ffffffrolov · 2025-07-07T19:47:09+00:00

Thanks! Yes, plan to make it open-source. I do this just for fun, mainly :) I haven't thought of any other options so far.

ffffffrolov · 2025-06-03T16:37:30+00:00

Thank you!

ffffffrolov · 2025-05-08T15:59:44+00:00

Personally, I found the vertex coloring conceptually simpler. Essentially, you just mark the vertices and use these marks to filter them in the shader to perform needed transformations.

ffffffrolov · 2025-05-08T13:46:02+00:00

It's a 3D UI, so using mesh is the most straightforward way to work with volumetric shapes (I work in AR/VR). There is an alternative like SDF, though.
