Prefacing this question by saying I have no idea what I’m doing. Been reading for a few days about how I could make a field of grass, and curious if my conclusion is roughly right. As far as I can tell, there is no geometry shader, but if there was then this would be a good option. The other method…

There’s a lot of options and my beginnerness is overwhelmed. I’m glad I asked my question though! In one of the links above, there’s a reference to this page which I think is interesting. Aesthetically it’s exactly what I want. Just slow for me to understand the method. Maybe a sign I need to eat br…

Yes, at first sight, it looks like a good approach and some nice slick code. To be honest, I just had a quick look at the script, didn’t even see what it does. It’s based on angle and instanced/buffered arrays and is creating patches of grass with a certain level of interaction. I’m not sure what yo…

Adding @syntheticmagus who did a bunch of grass rendering experimentations

I’d be curious. So far I like the method of 6-10 vertices per grass blade, just a flat plane, so each blade is identical; then using custom attributes for the vertex shader to change each blade’s position/rotation/time/height/curvature. I think that’s what the playground in the thread above does ( h…

Apart from a fairly high inter-frame time and some freezes on cam movements when testing on an old rig (1gb GPU medium-range from a decade ago and slow memory, still 8 core CPU at 2.8Ghz), it seems to work pretty well. Of course on a newer system, (an MBP from late 2019 with 4gb GPU still medium ran…

I tried to create realistic grass with the Fur material. It’s quite convincing and I think it’s the best in terms of loading and FPS Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes [2022-04-04 21_47_16-Greenshot…

It’s amazing! Thanks for sharing

You’re welcome. I think that with another texture it could give even better results.

I was curious how it’d work on a different computer. Glad it’s not too bad. Could make grass a graphics option if necessary. I hope there’s still opportunity for performance improvement.
