Show HN: 3D-Parallax, labelfree 3D experience from a 2D image using parallax

I don't know what's the "it" that you mean. I simply think that this piece of work would greatly benefit from some image or video examples of the technique being applied in practice, especially to help people who are not very acquainted with 2D and 3D image processing.

For instance, I can only imagine right now how this technique works; I'd rather not leave that to my very imperfect imagination.

Earlier quoted context omitted.

I don't know what the intent of the op was, but a lot of times repos are submitted without proper readmes, explanations or examples, such that it feels like "working out the usefulness of this thing is left as an exercise for the reader".

"We offer an experience of 3D on a single 2D image using the parallax effect, i.e, the user is able move his real-time tracked face to visualize the depth effect."

Since there are no examples I can't be sure if this is is what I think it is, but IF it is:

I want this on huge monitor for any 3D game instead of clunky headgear VR or tiny smartphone AR.

Months ago I also tested this with a small 3D visualization and very crude head tracking.

The effect is damn awesome! To be able to move around in real space with the rendering adapting to it, makes it so immersive, even for my very crude tests.

In my opinion the resulting 3D effect is MUCH better than viewing in stereo with one picture per eye.

Here is an example from someone else from 2007:

From 2012:

Obviously this works for only one person viewing it, but does that really matter? There are a LOT of use cases where only a single person uses a single monitor for viewing, especially in these times. In fact it is the standard.

How do you calculate the angle between the persons eyes and the screen, in order to render the parallax effect?

I wonder if this could be use for better videoconferencing.
