why touch grass when you can make fluffy grass for game (and maybe make it an plugin for the Godot editor for the public to use ).
thinking on add trampling to the grass so that the player can interact with it.
and the reference that i used to make grass in the above screenshot are.
and some nvidia GPU gem articles that helped for added no how for wind .
Chapter 7. Rendering Countless Blades of Waving Grass | NVIDIA Developer
Is it possible to create human hair using this principle?
Nope I guess.
maybe. but the technique is limed .
did some research on the demo that @tomcat showed above and think it use a technique from this .
from GPU gem 2.
from what i have read of the article it is vary complex algorithm to create in Godot and other 3D software.
found this as wall for hair .
This demo ran perfectly on Windows 7, but it absolutely refuses to work on Windows 11.
So, should we not expect to see hair like this in Godot?
But grass is nice, too. 
have you try ruing the demo in a offline VM of Window 7?
i mean you have open source hair framework like AMD’s TressFX but it has no way of integrate with Godot. and it is Old by modern graphics standers. and Vulken can do hair rendering from the example on GitHub.
you have to see if Hair rendering prioritize in later Godot version like 4.7 or 4.8 Maybe or even Godot 5.0
No. I ran it on an ancient real desktop running Windows 7.
I just need hair (among other things) for my project, and I’m looking for at least a minimally suitable solution.
