Sand Table Pattern Maker

Launch Pattern Maker

This is part of my Sand Table Build

Built with p5.js

Installation

npm install
npm run dev

Controls

• Press "o" to toggle an overlay of the pattern settings in the canvas
• Press "c" to toggle the live coordinates and plotter mechanism view
• Press "d" to download a heightmap PNG of the pattern.

How to Build a New Pattern

In order to build a new pattern a few things must be done:

1. Create a Pattern Class and save it to the assets/js/patterns folder
2. Link to Pattern Class file in index.html
3. Add the Pattern Class to the Patterns config in the main sketch file (sand_table_pattern_maker.js). This object must have a key that matches the class's this.key value and the object value must be a Class instantiation.

Pattern classes are made up of at least 4 methods:

• constructor - The class constructor defines a few aspect of the class including:
  • this.key - Used for identifying the class's properties in the main sketch file
  • this.name - Used for referencing the pattern in the UI.
  • this.config - This is an object that defines the pattern's input configuration options.
  • this.path - Initializes the pattern's output path coordinates
• draw - This class is called by the main sketch to draw the pattern. It reads and updates the UI input values and sends the input to the class's calc method.
• calc - This is where the algorithm for the pattern is implemented. Using the selected inputs, the method returns the coordinates for the complete path.

Once you've completed your design, submit a Pull Request and if it works, I'll merge it in. Thanks in advance!
