If your wonder what really amazing realtime grass might look like in a video game. (Fifa 17) https://youtu.be/WLsPstW0iGQ

Does Fortnite feature the same algo?

Isn't the grass on that video just a hi-res bitmap texture on flat ground? Sure looks like it.

I'm not sure, it's hard to see on that video, but it doesn't seem flat if you look at the players' shadows.

Nah, it's more like fur rendering. It looks like they do some raytracing to intersect with virtual grass blades.

well that was kinda disappointing - to me it looked like the players float slightly above the grass rather than in it and they leave no footprints nor disturbance. Now of course its damn nigh impossible with current hardware to do footprints and disturbance but, all the same, was hoping all the extra umph of modern hardware would get us there sooner.

I don't know. Considering it's like 8 years newer I'd say this doesn't look as good as Flower did in 2009:

Granted, the animated grass rendering was the main feature of that game, so it probably had a lot more time budget than a game like Fifa can allot to it.

That video isn't very good - this one provides a better idea of the image quality of Flower:

The poster child for me at the moment is Ghost of Tsushima: https://www.youtube.com/watch?v=kSAvzeopPC8.

Also I think Horizon Zero Dawn has very impressive vegetation, and it came out last year even.

I just want to remind people what an "Archaeologist Adventure" game used to look like:

Vs what it looks like recently:
