A linked volumetric representation for graphical objects is presented together with techniques for physically-plausible modeling of object cutting, joining and tearing. In one embodiment, each element is may be explicitly linked to its six nearest neighbors by storing pointers to those neighbors in the element's data structure. The link between two elements can be cut when a graphical representation of cutting tool passes between the elements by setting the appropriate neighbor pointers in the two elements to point to NULL instead of to each other.
