  • 1. Changing the solid space over time
  • 2. Moving the point being rendered through the solid space

The first approach has time as a parameter that changes the definition of the space over time, a very natural and obvious way to animate procedural techniques. With this approach, time has to be considered in the design of the procedure, and the procedure evolves with time. Procedures that change the space to simulate growth, evolution, or aging are common examples of this approach. A related technique creates ...
