How to merge the two meshes?

[bestxhh]

hi guys

 

I now do two kinds of ripples

 

But I don't know how to get them together.

 

I've tried ray but the shape will change.

 

I should how to integrate the two effects without changing the form??

 

thanks！

I now want to merge the two ripples onto a grid

 

I used intersect under the VOP it can only fusion half

 

I think it's not good for me to do.

 

help me

 

thank you

In this case you could probably get away with just ray'ing one of top of the other. For more complex setups/shapes you can use VDB's, but as I said, don't think it's necessary in this case.

 

Edit: Oh, I just got to think about how you set this up, if these are just out of the ripple solver, you could probably just feed one solve into the next one, thus stacking the effect instead of solving one, then another and combining them.

if your grid has the same topology for both of them and you have stored rest attrib of initial flat grid then you can just connect them both into wrangle and do:

vector a = @P-v@rest;
vector b = point(1, "P", @ptnum) - v@rest;

@P = v@rest + a + b;

Oh, that's even easier, just add them together.

Thank you for your help.

I have solved it.

I make it too complicated.

I ended up with two P.y.

Oh, my God. I think my brain is eaten by zombies.
