Adjust the rules to create a field of grass



Design your grass.

The sliders change five parameters of the blades of grass: number, distribution, color, length, and curvature. You can also control the amount of variety.


Run the program.

Click on the Generate grass button on screen to apply your rules. Click and drag the screen to change your view.


Revise the rules.

Edit the rules until the grass looks the way you (and the director) want it to look. What other parameters might you like to add to this program?
