Special effect

The temptations and pitfalls are to go too far -- to exaggerate too much and just put things on the screen because you can put them in. To me, the most important thing is the characterization: to know them, to understand them and appreciate them. The effects are just to allow you to depict the characters as WELL and vividly as possible.

Some of the physical phenomena commonly simulated in movie and video game special effects include water, fire, smoke, explosions, rigid body dynamics, and the deformation of elastic bodies. The governing equations for these processes are most often in the form of a system of partial differential equations.
