Camera projection done in Maya and Photoshop. The explosion is done using the Voronoi script for the shatter, customized to concentrate the shards in the center of the shattered mesh, then simulated using Dynamica. The debris and and dust are done with nParticles and expressions and rendered in mental ray.
