Description

This project is to implement the L-System.

I also implmented a dusty, orange background by fbm noise function to incorporate the autumn theme.

Drawing Rules

• F: expand forward and scale down a little bit
• L: draw a leaf
• +: rotate positively around Z axis
• -: rotate negatively around Z axis
• ~: rotate positively around X axis
• *: rotate negatively around X axis
• =: rotate positively around Y axis
• _: rotate negatively around Y axis

The axiom is FX.

Randomness

The rorating amount is an angle with some random offset added.

Controls

• Iterations: change the number of iterations in L-System
• Angle: change the angle in L-System
• leaves_color: change the color of leaves
