Field of grass?

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 think we can work on this but as i see using texture have better result and optimizing in the Mobile side

Hi @Dad72,
Saw your attempts to improve but it doesn’t change much from the original issue. I think (as you said) combining with other techniques might be the best way to further improve (what is already awesome, I say it again). And yes probably working the texture could help. Obviously problems appear most on the upper part of the grass, which is perfectly understandable because of the top down view of the texture.
So yes, as @nima says I wouldn’t attempt to increase the quality/load but rather work the integration with texture and combining with other techniques.
I can see the ‘grass topic’ seems to be very appreciated by the community.
Bookmarked and will continue to follow and if I get a chance, will eventually try contribute (not just soak-up :wink:

Thanks for sharing. That looks amazing :heart_eyes: and the text saying you can customize per point Color4 sounds really cool :yum:. You mentioned a website… would you have a link to share with us?

This is great. I love all the different “kinds of plants” you can produce with it. Thanks!

Indeed, awesome.
Thank you to the unknown creator.
I am just the finder - I found it in the playground this morning :slight_smile:

crazy demo！high performance and low computation cost

Here is a nice explanation about how to create a grass simulation in GLSL. Useful to create some other type of 3D space simulations.
