Introduction

In the previous module, we gained some fluency in reading source code and making minor modifications to it. Our visible output was mostly white lines on a black background. We will now revisit what we learned, instead placing colorful pixels in a rectangular canvas. Our context for employing these new skills is territorial design: we will calculate Voronoi cells as models for delivery zones for pizza restaurants.

Learning outcomes

This module will help you do the following:

• Draw on a canvas
• Calculate distances
• Produce a return value from a subroutine
• Group values in tuples
• Express colors in RGB
• Generate pseudorandom numbers
• Employ logic to establish conditions

Concepts

After this module, you should be familiar with the following concepts:

• Distance
• Condition
• Optimization
• Minimization
• Objective
• Territory
• Voronoi diagram

Remember that you can always look concepts up in the glossary. Should anything be missing or insufficient, please report it.
