Astroboy: breaking complex geometries with Voronoi diagram

In Astroboy , breaking geometries is a very common effect. Sometimes a high level of user control is required to break an object in the right way. This is often done by adding edges manually. Time investment is huge and the result cannot be edited easily. Even in the case that the appearance of the pieces is less important, the geometry to break can be very complicated, for example, a building, that any manual editing becomes prohibited in tight schedule. We thus developed a three phrase fracturing system that can automate the breaking process, while also allow certain level of user control.
