p5.asciify `"accurate"` renderer plugin

| |:-------------|:-------------|:-------------|

A renderer plugin for the p5.asciify library that provides an additional renderer option "accurate" to add to any rendering pipeline. This renderer attempts to pick the most fitting ASCII representation to accurately represent the input sketch using the available ASCII characters.

Installation

Prerequisites

Plugins renderers require p5.asciify version 0.9.5 or later.
The plugin is compatible with all p5.js versions that are compatible with p5.asciify.
- This includes p5.js versions 1.8.0 to 1.x.x, and p5.js versions >=2.0.2.

Importing the plugin

Global mode

Download the latest umd version of this plugin from the GitHub releases page or import it directly from a CDN like jsDelivr. The plugin is distributed as a single JavaScript file, which you can include in your project by adding the following script tag to your HTML file after importing p5.asciify:

<!-- Import p5.js before p5.asciify -->
<script src="path/to/library/p5.min.js"></script>

<!-- Import p5.asciify after p5.js -->
<script src="path/to/library/p5.asciify.umd.js"></script>

<!-- Import the plugin after p5.asciify -->
<script src="path/to/library/p5.asciify-accurate-renderer-plugin.umd.js"></script>

Instance mode

Download the latest esm version of this plugin from the GitHub releases page, import it directly from a CDN like jsDelivr, or install it using npm:

npm install p5.asciify-accurate-renderer-plugin

import p5 from 'p5';
import { p5asciify } from 'p5.asciify';
import { AccurateRendererPlugin } from 'p5.asciify-accurate-renderer-plugin';

const sketch = (p) => {

    let asciifier;

    p.setup = () => {
      p.createCanvas(800, 800, p.WEBGL);
    };

    p.setupAsciify = () => {
      p5asciify.registerPlugin(AccurateRendererPlugin);

      asciifier = p5asciify.asciifier();
      asciifier.renderers().disable();
      asciifier.renderers().add("accurate", "accurate", { enabled: true });
    };

    p.draw = () => {
      p.clear();
      p.background(0);
      p.fill(255);
      p.rotateX(p.radians(p.frameCount * 3));
      p.rotateZ(p.radians(p.frameCount));
      p.directionalLight(255, 255, 255, 0, 0, -1);
      p.box(800, 100, 100);
    };
};

let myp5 = new p5(sketch);

Usage

To use the "accurate" renderer, you need to register the plugin with p5.asciify using registerPlugin(AccurateRendererPlugin), and add it to a rendering pipeline of a P5Asciifier instance. The "accurate" renderer can then be used in the same way as the pre-defined "brightness" renderer.

```javascript let asciifier; let accurateRenderer;

function setup() { createCanvas(800, 800, WEBGL); }

function setupAsciify() { p5asciify.registerPlugin(AccurateRendererPlugin);

asciifier = p5asciify.asciifier(); asciifier.renderers().disable();

accurateRenderer = asciifier.renderers().add("accurate", "accurate", { enabled: true });

accurateRenderer.update({ enabled: true, // redundant, but for clarity characters: " .:-=+*%@#", characterColor: "#ffffff", characterColorMode: "sampled", // or "fixed" backgroundColor: "#000000", backgroundColorMode: "sampled", // or "fixed" invertMode: false, // swap char and bg colors rotationAngle: 0, // rotation angle in degrees flipVertically: false, // flip chars vertically flipHorizontally: false, // flip chars horizontally }); }

function draw() { background(32); fill(255); rotateX(radians(frameCount * 3)); rotateZ(radians(frameCount)); directionalLight(255, 255, 255, 0, 0, -1); box(800, 100, 100); }

function windowResized() { resizeCanvas(windowWidth, windowHeight); }
