Unexpected result with Kangaroo physics

by McKinnley Workman

Nov 27, 2011

Hey guys,

 

Expected result is that the force vectors deform the dome/building when Kangaroo component is toggled to false but instead nothing happens. Should be a simple execution right? What am I missing?

 

Insight would be much appreciated.

Thanks

    just have to connect the time component to the kangaroo physics engine and turn to false the boolean....it does something, but maybe not what you expect.

      Hi McKinnley,

       

      Kangaroo works essentially with particles/points. The points are what forces get applied to and what gets moved.

      The force objects create relationships between those points - for example a spring tries to keep 2 particles a certain distance apart.

      It is possible to use the points of any geometric object in the simulation, but relationships between points do not exist unless you create them by adding a force. In the definition you posted there is a force acting on the points around the cylinder, and they get moved, but there is nothing linking them with the dome.

      You have made some of the edges of the dome springs, which is a start, now to make the dome deform you would need to apply forces to the ends of those springs.

       

      hope that helps
