Fem balloon inflate/deflate

Recommended Posts

Hey,


See attached. I found this example in another thread (totally forgot which one, sorry!). 

I have some questions about this setup:

- This is the first time i have seen targetV used rather than just v. What is the advantages of targetV over v?

- How would you go about "deflating" the balloon? I tried just negating the targetV, with little success.


Cheers,


Nick

Consider that if you set a "v" you are forcing a velocity for a point, exactly that velocity. "targetv" works like a goal, you're not setting a hard value for the velocity, just a goal and the solver try to reach that velocity.

Something like this can help with the "deflating"?

Hey,

 

Sorry for the late reply.

 

TargetV: Makes sense

 

Deflate: The old position vector, that should do the trick :)
