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…

Another playground! Some neat additions I see from an earlier version you made: Multiple zones with 1 mesh per zone. LOD variants to have different segments per base blade. The method of making a base blade, then pushing a bunch of clones into one merged mesh remains roughly the same. If I underst…

Wow, thx so much @Dad72 for this experiment. It really looks amazing, loads fast and works beautifully at high FPS even on lower end rigs. The only point is when looking closer you get a bit of this edged look rendering. I believe this can be tempered with the texture. Quickly added a rendering pi…

It rocks!! This is a good candidate for a tweet @PirateJC

Yes I also think it can be further improved with another texture (texture has thick grass, so it’s not the best of the textures I’ve used) Maybe a rendering pipeline would improve things too. in my PG I used a diffuseTexture : grassMaterial.diffuseTexture = new BABYLON.Texture("textures/grass.jp…

I made some adjustments to improve the result. But I can’t made better. Changing texture (grass.dds instead) just changes colors. I increased the density a little which reduced the thickness of the grass. Maybe something is missing in the material to reduce the thickness rather than increase the d…

I wonder what it could give by mixing the version with ShaderBuilder from nasimiasl and the Fur material with a lower density. For the moment I remain more convinced by the result with the Fur material. Nasimiasl’s version however has finer grass, but more holes. The result is interesting.

@Dad72 it would be cool to take this process but reverse the raymarching and do it inside an inverted cube, that way it could depth sort with real meshes and be longer blades then what can be marched on a single plane.

@Dad72 this is awesome! You’ll see a tweet go out tomorrow morning on this!

I don’t use tweeter. I am registered but I do not use it. But thanks :smiley:
