Contact Clustering for Deformable Soil Interaction

I. García-Fernández, M. Lozano, M. Pla-Castells and J.M. Orduña

Presented at the ACM Siggraph/Eurographics Symposium on Computer Animation 2012 posters session.


Deformable soil simulation involves the computation of interaction forces and of the deformation suffered by soil. According to experimental studies, the deformation suffered by soil under a vertical pressure p depends on the size of the contact patch.

If soil is represented by a height field, after collision detection we have a list of contact points. If the list of contact points correspond to several contact patches, in order to obtain their size we need to group the points.In our poster Contact Clustering for Deformable Soil Interaction we propose the use of hierarchical clustering for this purpose.

In this video you can see the sequence of clusters generated during a collision of a box against bumpy soil.
