Baking a 3D scene onto a plane using hexagonally packed... panoramas 8192x8192 image texture with ~50k spheres on it to create this 😂 #b3d

This is basically how most lightfield image capture works. Very cool!

Can't imagine how it would be realized. That requires too many pixels and perfectly aligned optics😂

Hope you don't mind, I made a slight upgrade to the lens shader- now it acts as just another wall for bounce lighting, giving more consistent shadows. (if you wanted to use lighting outside the box, you could also use a transparent shader.) (more explanation in image alt text)

Wow nice,such simple fix prevent the setup from interfere the scene! 👍

And I was proud of finally figuring out a parallax mapping shader. This is honestly incredible

@JitJoel Actually, I want to study parallax mapping too😂 Do you have any recommendations of article/tutorials?

What kind of machine you use to process such complexity in real time?

I use a 3090 + i9 here, but as long as the texture size can be handled, the final product will be real-time on most machines (I think). Disclaimer: baking takes a very long time. That's 50k panorama, each about 40x40px 😂

One cool trick you can also do is render a camera to a texture and apply it to a plane. If you put a constraint between the main camera and the "texture camera", you can create a "3d window", which is good for physically impossible effects, like windows falling from the wall.
