I feel like the topic just scratches the surface; there are many more things that are way more interesting to talk about here.

For example: air density actually matters. Professional players sometimes struggle to make shots in different parts of the world. The balls are not the same either. Comparing DHS with Nittaku, for example, they have different properties and a different bounce. In my part of the world, DHS is the preferred ball, compared to the US, where, at least where I’ve been, they prefer Nittaku balls.

Now about the content:

The Bounce: This could have shown all three balls at the same time, instead of showing them one after another. That would make the effect clearer.

The Answer: This feels a bit odd, and I think something in the calculation is wrong because the usual push always goes over the table on backspin.

Overall, I get that this is a very simple representation of what table tennis is, but it gives me “I did it in 5 minutes with AI” vibes.

Also absolutely horrible UI and seems like you just put up whatever Fable shat out without checking or any thought. I am only saying this because you shared it for public feedback

Thanks Fable, we miss you

It visualizes topspin/backspin, spin rate, ball trajectory, bounce behavior, and why the opponent’s return reacts the way it does.

I built it because spin is central to table tennis, but most explanations are either too hand-wavy or too static. I wanted something you can scrub, slow down, and experiment with.
