p5.mapper

p5.mapper is a projection mapping library for p5.js. This library makes it easy to code and keystone interactive, algorithmic sketches. Created by Jenna deBoisblanc.

• Examples
• Reference

You'll find the library, p5.mapper.min.js, in the dist folder of this repo. Include the library in your index.html (after loading p5.js).

<script type="text/javascript" src="p5.mapper.min.js"></script>

Inside the sketch.js:

const pMapper = createProjectionMapper(this);

// quad, triangle, lines:
const quadMap = pMapper.createQuadMap(400, 400);
const triMap = pMapper.createTriMap(300, 300);
const lineMap = pMapper.createLineMap();

// mask with 6 moveable points
const maskMap = pMapper.createMaskMap(6);

// draw()
quadMap.clear();
quadMap.background(255, 0, 0);
quadMap.fill(255);
quadMap.ellipse(100, 100, 100);

triMap.clear();
triMap.background(255, 255, 0);

lineMap.display(color(0, 255, 0));

maskMap.display();
