By the'explosion, high dense and high pressure detonation products gasses expand rapidly and extremely strong shock waves are driven. The three-dimensional simulation is executed for the propagation of the blast waves driven by TNT32kg explosion in the underground magazine. We present an effective visualization of the fireball, and the key idea for the fireball with complex surface illuminated by the black body radiation is the combination of volume rendering with iso surface rendering based on a pure ray tracing method.
