Hi kintuX, thank you much for your story.

Sure, for other eyes you can pass through or below a rainbow, but you cannot see it with your eyes and you cannot look at the back side of a rainbow, could you?

In reality you cannot pass below a rainbow

These pictures are more than amazing, they are unique!

How did you update and from which version?

Nice Nvidia demo, but it is only a demo. Some guys tested the so called real time ray tracing. In fact it is not feasible yet. You need at least 4 to 16 samples per pixel and this is not much as we know. They optimized a lot. Let us wait for cards with more than 100 Tflops for 32 bit floats with tdp...

Simply virtual.

Some ‚basic‘ knowledge behind rendering materials leading finally to holographic textures. Nice illustrated in this presentation:

Nice example in there with reflections of CDs.

🌈 Rainbow: This tipic is actually much complexer than ny basic understanding of optics considers it. Although I was ble to simulate a faint noisy rainbow with current luxcore it might be not possible to render an acceptable image. Who ever is interested in that matter I suggest to look at this paper...

Thank you for sharing time requirement. I think you are pretty fast considering all the details and perfections in your pictures.
