Questions about the real-time GUI shown in the demo

[Kooroshoo]

Hi,

I recently watched your demo: https://www.youtube.com/watch?v=ggfsGD1PCQA&t=1s and was curious about how this setup was implemented.

From my understanding, achieving a similar result would require using the Nyx library. However, Nyx appears to be a headless library and does not seem to provide a GUI out of the box.

Could you clarify how the GUI shown in the demo was built? In particular, I'm interested in how you were able to visualize the scene and tune the Gaussian parameters interactively in real time.

I also have a question regarding performance. Is the demo actually running in real time? Looking through the Nyx examples, I couldn't find any examples that appear to run interactively at real-time frame rates, so I'm wondering whether the demo uses additional components or optimizations that are not part of the public examples.

Any details about the architecture, tooling, or integration used for the demo would be greatly appreciated.

Thanks!
