Hi there.

My name is Sanaz Zarghami and I am the master student of Digital Technology Architecture in Iran. I need to have some Basic information on how to work kangaroo for my final thesis. I deeply appreciate your help to get it done.

Giulio - Yes, the collisions below and the surface relaxation are using classical Newtonian/Hamiltonian mechanics and are deterministic.(Though things like the colliding balls are chaotic in that they are highly sensitive to initial conditions).
Random forces/displacements like those in the DLA thing I posted could certainly be added though.

Hi Daniel,

I mean in both the relaxation and collision examples is the algorithm deterministic or it takes into account some stochastic model? Tha is to say...for a given configuration will the result will be always the same? Is the interaction btw points/meshes following newtonian mechanics? Have you some refernce for the relaxation algorithm?
thanks

@Luis - Thanks, yeah I was really sorry I couldn't be there. Looking forward to hearing all about it and still hope to be back in Barcelona before too long.
@Giulio - I'm not sure I quite follow. What sort of stochastic model do you have in mind ?

Hi Daniel,
very interesting. Did you manage to implement a stochastic model as well within the algorithms ?

Excellent stuff man! Missed you today at the User Meeting in BCN!

Testing collision responses :
(Just between spheres, points and the floor plane so far. I might get on to collisions between moving geometry and fixed Breps later, but the general case of all moving geometry being able to collide with all other moving geometry is too much of a headache for now).

Now he's just teasing, giving us a snippet every other day.
looks really amazing daniel!
