# lab03-grammars
Let's practice using grammars! For this lab, please pull up the L-system node in Houdini.
Team members: Keyu and Kehan

## 1. Wheat grammar puzzle
Look at these iterations (n = 1, 2, 3) of a one-rule grammar. Using the built in symbols in Houdini, design a grammar that produces this output. Take a screenshot of your rules.\

## 2. Square grammar puzzle
How about this one? Take a screenshot of your rules.\

## 3. Custom plant
Choose a plant in the world. Working off a reference, design a grammar that mimics the structure of that plant. Unlike our simple puzzles, please use multiple rules for greater complexity. Think carefully about the structure of your grammar! EXPLAIN the structure of your plant in the README. What are the components? What do each of the rules do? Be sure to also include images of a few iterations of your output plant.
Explanation: We tried to create some symmetric trees like a pine tree. We used multiple rules for this one. The rule F=FF makes the branches longer, and the rule with X creates branches with rotations and allows for a symmetrical branches. We tried a few generations and n=10 and n=5 which look nice are shown below.

## Submission
- Create a pull request against this repository
- In your readme, list your solutions and format your README nicely
- Profit
We also experimented with single rule grammar and put here just to show. At n=4 they look nice.
