Water Lilies

[Timursq]

Hello,

 

I was wondering if I could get some advice on how to best approach Water lilies?

 

Currently I have an ObjectSlice node to cut the branches at water level.

 

I am using a Vector direction curve to point the ends straight up and am able to align most leaves this way but not all of them. Is there a better way to align the leaves to the surface of the water?

 

Also is there a better way to distribute the leaves on the water, so they are not overlapping, than to manually place them with the Shape modifier node? Is there maybe some sort of branch collision system that could be implemented?

 

One problem with the Shape modifier node, besides being manual, is that one cannot copy the modified positions into another growFX instance, that I need to convert to mesh.

 

Any advice appreciated.

Hello Timursq,

 

I looked at your plant, and I think it's possible to align the leaves, but avoiding collisions is more difficult. There need to reduce the number of leaves, or make the whole plant wider.
I can try to recreate your plant, but I wanted to ask, do you want to get this lily with wind animation?
It's just more difficult to do with the wind without leaf collisions.

 

Thanks!

Hi @Eduard,

 

I included the wind not for the animation but for the flowing shape that it gives to the stems, which seems to look more natural, and water-y, than I can do just with VectorDirection.

 

(These will eventually become 3d prints cast into steel, or aluminum, that's also why the heavy leaf meshes.)

 

Thanks for taking a look into it!

Hi @Eduard

 

just to clarify: how would one be able to align the leaves without wind?

 

Thanks!

Hi Timursq,

 

I think Vector direction can do this easily.
Since your leaves are objects of instanced geometry, you can direct the path lines straight up using Vector direction, and place leaves on them.

Just turn the pivot of the leaves so they are oriented correctly.

 

BTW, we found a bug with Vector direction, but we've already fixed it, and will soon update all the files on the server.
The problem was that with a large Strength value, the path lines was greatly distorted.

 

Thanks!
