Overview of modeling grass with parabolas
Welcome to environment modeling!
In this topic we're going to explore how realistic blades of grass are modeled using parabolic arcs.
This topic contains two lessons:
- Appropriate for grades five and up
- Design your own blade of grass using midpoints and simulate it as a flowing field.
- Appropriate for grades nine to 12
- Discover the equation used at Pixar to efficiently draw parabolic arcs.
