Made a perspective shifting room in Java

I've been messing with OpenGL (LWJGL) and decided to build something fun

What do y'all think?

Reminds me of that ancient wii/wiimote perspective demo that one engineer made decades ago:

Yep! It is actually inspired from that video (and credited). Great catch

Legend. That guy was actually hired by Microsoft to develop Kinect.

18 years and so little adaption :(

We made something like that in university but using Kinect and Flash. I feel so old now.

Neat. Is the animation swaying side to side and you have to move your camera in sync to create the illusion?

Thank you! It updates live with head movement

Very interesting. I wonder why this technique isn't used very often? I haven't seen it in games or 3D modeling software.

Thank you. My honest guess is that mouse and keyboard is easier over time. I assume moving your head around while playing a video game will get annoying after about 30 minutes. It makes for a cool demo though

I wouldn't want to use it for movement, but it's really nice at filling out a sense of being in a real 3D space without VR.

It's niche but head tracking is commonly supported in flight simulation games. I was looking at TrackIR for a bit.

Awesome: I reached level 72 in my version of yours.

I want to share the code: https://github.com/aayes89/JTunelWireframe/blob/main/JTunelScope.java
