What is it about?

Artists often have the need to alter fluid simulations. The problem is that re-running the simulation is too time consuming. This system we describe here allows users to interactively edit and alter fluid simulations, such as widening a simulated river or shrinking a dam break simulation.

Why is it important?

This system allows artists and others to alter realistic simulations in realtime. Once the fluid simulation has been run, it can be altered to meet artists needs without the cost of re-simulation.


Fluid simulations (water, smoke, fire, etc.) are becoming increasingly desirable in movies and animations. Having the ability to interactively edit a simulation can save artists a tremendous amount of time and can help them create realistic fluids in a much shorter time than has been possible.
