Now I will show a short video from our system. Using a scanned mesh of an Egyptian cat, we created a volumetric model with three layers. Here we show an interactive visualization of the model, by clipping it first in the z-plane, then in the x-plane.

We interactively sculpt the model, first with the hammer tool. We have specified that only the brittle fired clay will be affected by this tool. The clay is fractured and broken away from the model. This model has approximately fifty thousand tetrahedra. We have disabled collision detection for this session to improve interactivity.

Next, we clean and polish the statue with a sphere-shaped tool that removes fired clay and brightens and shines the bronze material. All of these actions are automatically logged to a script file. Details of our interactive fracture and rigid body simulation are available in my co-author's paper from last year's Eurographics Workshop on Animation and Simulation.
