Description

Visualize p5.js arc drawing modes (OPEN, CHORD, PIE) with interactive start and stop angles in degrees and radians.

Learning Objectives

  • Primary Goal: Students will master the arc() function syntax, angle direction in p5.js, and how mode parameters alter geometry.
  • Bloom's Taxonomy Level: Apply

How to Use

Interact with the visual elements and adjust the control sliders and buttons located beneath the simulation canvas to explore how parameter changes affect the output in real time.

Lesson Plan

Prerequisites

  • Understanding of basic coordinate systems and p5.js sketch execution.
  • Familiarity with variables and interactive event handling.

Interactive Exploration

  1. Observe the default initial state of the simulation.
  2. Adjust the sliders systematically to observe the range of behaviors.
  3. Compare the visual feedback against the theoretical concepts presented in the chapter.

Assessment Questions

  • How does changing each individual parameter influence the resulting visual output?
  • What underlying algorithm or mathematical model governs the state transitions shown in the simulation?
