A graphics system is described for simulating the interaction of two or more types of media on a simulated canvas. The graphics system performs this task by consulting a media adhesion matrix which determines a type of behavior that is produced when an attempt is made to add a new medium over the top of an existing medium. In one scenario, the new medium is a watercolor medium which does not apply over a hydrophobic media (such as an oil medium), but may tunnel under such hydrophobic medium in a flow layer during a simulation operation. Various provisions are also disclosed herein to improve the efficiency of the simulation operation. |
