Inflating

by Nicolas

Jun 3, 2017

Hi Everyone I'm starting to use Kangaroo2

It is amazing and super intuitive.

I'm trying to replicate things that are done in kangaroo 1.

It works like a charm.

I'm just having trouble understanding something

I'm trying to inflate a sphere inside a box, and it behaves in a weird manner.

When I apply pressure it moves upwards, even though it should stay still. since the pressures should pull equally in opposing directions. Then when it reached the boundary of the cage it just starts spinning out of control.

 

In the inflation plus collision examples from kangaroo 1, the mesh was more stable when colliding.

I attach the file, any help would be much appreciated.

Thank in advance, and thanks Daniel for such an amazing plug in

    this is because pressure goal works with triangles, even you input quad mesh it takes first 3 vertices of mesh face :

    the same goes with hinge goal even it does not give error it does not take into account 4th vertex

    the same goes inside component:
