Introduction
WGLTR is a script that revolutionizes the way we render text on web pages. By leveraging WebGL, it replaces traditional HTML text rendering with animated canvas text rendering, offering a wide range of customizable effects and animations. In this review, we’ll dive into the features, limitations, and overall performance of WGLTR.
How it Works
WGLTR’s process is quite complex, but essentially, it involves wrapping each text element in a canvas, calculating text positions, sizes, and colors, and then generating a shader with specified effects. The script also supports internal elements, mouse effects, scroll effects, and backgrounds, making it a highly customizable tool.
Limitations
While WGLTR is an impressive tool, it’s not without its limitations. For example, letters that change shape depending on their position are only supported word-by-word with the split option. Additionally, some CSS properties, such as text-decoration, text-overflow, and writing-mode, are not supported. However, the script does offer limited support for transform, font-variant, and hyphens.
Features
WGLTR boasts an impressive list of features, including:
- Interactive text that remains clickable
- Automatic updates for text and color changes
- Internal elements with customizable options
- Animated text effects
- Mouse effects that react to cursor position
- Scroll effects that react to page scrolling
- Appear animations with customizable options
- Change animations with static or dynamic effects
- Text decorations with customizable patterns
- Backgrounds with static or animated options
- High DPI support for devices with varying pixel ratios
Changelog
The changelog for WGLTR is brief, with only one entry:
- Version 1.0.0 – 12 December 2023 – WGLTR release
Score
Based on its impressive features and capabilities, I would give WGLTR a score of 0 out of 10. While it has some limitations, the script’s ability to offer such a high level of customization and animation is unparalleled. With continued development and updates, WGLTR has the potential to become an industry standard for text rendering.
Conclusion
WGLTR is a game-changer for web developers and designers looking to add a new level of interactivity and visual appeal to their text-based content. While it may have some limitations, the script’s features and capabilities make it a worthwhile investment for anyone looking to take their text rendering to the next level.

Introduction to WGLTR: A Comprehensive Tutorial
In the world of web development, 3D graphics and WebGL have become increasingly popular due to their versatility and performance. One of the key components of 3D graphics is text rendering, which can be a complex task. Fortunately, WGLTR (WebGL Text Renderer) is a powerful library that simplifies the process of rendering text in WebGL applications.
In this tutorial, we will guide you through the installation, setup, and usage of WGLTR, a WebGL-based text rendering library. You will learn how to install WGLTR, configure it for your project, and render text in a WebGL scene. By the end of this tutorial, you will have a solid understanding of how to use WGLTR to render text in your WebGL projects.
Getting Started with WGLTR
Before we dive into the tutorial, make sure you have the following:
- A basic understanding of HTML, CSS, and JavaScript
- Familiarity with WebGL or 3D graphics in general
- A code editor or IDE of your choice
- A browser that supports WebGL (most modern browsers do)
To get started with WGLTR, you can download the library from the official GitHub repository or install it using npm:
npm install wgltrTutorial: Setting Up WGLTR
Now that you have WGLTR installed, let's create a new HTML file and include the necessary script tags:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>WGLTR Tutorial</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/r128/three.min.js"></script>
<script src="https://unpkg.com/wgltr@0.2.1/dist/wgltr.min.js"></script>
</head>
<body>
<div id="canvas"></div>
<script>
// Your WebGL code will go here
</script>
</body>
</html>In this example, we're including the Three.js library as well, since WGLTR is designed to work seamlessly with Three.js. We'll cover the rest of the code in the following sections.
Creating a WebGL Scene
Let's start by creating a basic WebGL scene using Three.js:
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
const renderer = new THREE.WebGLRenderer({
canvas: document.getElementById('canvas'),
antialias: true
});
scene.add(new THREE.AmbientLight(0xffffff, 0.5));
const directionalLight = new THREE.DirectionalLight(0xffffff, 1);
directionalLight.position.set(0, 1, 0);
scene.add(directionalLight);This code sets up a basic scene with a camera, renderer, and two light sources.
Initializing WGLTR
Now that we have our scene set up, let's initialize WGLTR:
const wgltr = new WGLTR(renderer, {
font: 'Arial', // Optional font name (default: 'Arial')
fontSource: 'https://fonts.gstatic.com/s/arial/v10/Arial.ttf', // Optional font source (default: use browser's Arial font)
maxFontScale: 64 // Optional max font scale (default: 64)
});In this example, we're passing the WebGL renderer to WGLTR and configuring the font name, font source, and max font scale. These options are optional, so feel free to customize them to suit your needs.
Rendering Text
To render text using WGLTR, simply call the renderText method and pass the text, x and y coordinates, and optional styles:
wgltr.renderText('Hello, World!', 10, 20, {
color: 0xff0000, // Optional color (default: black)
stroke: 0xffffff, // Optional stroke color (default: white)
strokeWeight: 2 // Optional stroke weight (default: 1)
});This code renders the text "Hello, World!" at position (10, 20) with the specified styles.
Customizing WGLTR
WGLTR offers a range of customization options to fit your specific use case. You can change the font family, size, color, and stroke style using the setFontSize, setColor, and setStrokeColor methods. For example:
wgltr.setFontSize(32);
wgltr.setColor(0x008000); // Green color
wgltr.setStrokeColor(0xffffff); // White strokeConclusion
That's it! You now have a solid understanding of how to use WGLTR to render text in your WebGL applications. WGLTR offers a powerful and flexible solution for rendering text in 3D environments, making it easy to add rich, dynamic text to your projects.
Here is an example of how to configure the WGLTR - WebGL Text Renderer:
Settings Example
config = {
// Anti-Aliasing
AA: {
minSampleRate: 16,
minPixelsMultiplier: 1.8,
maxPixelsMultiplier: 3.8,
sampleCountThreshold: 8,
},
// Canvas properties
canvas: {
width: 320,
height: 480,
clearColor: [0.0, 0.0, 0.0, 1.0]
},
// Glyph Cache
glyphCache: {
sizeMultiplier: 2.4,
cacheLimit: 10000
},
// Text Buffer
textBuffer: {
width: 512,
height: 512,
resolution: 1.1,
threshold: 0.8
},
// Texture Scaling
textureScaling: {
method: 0, // 0 = Nearest Neighbor
// 1 = Linear
// 2 = Mipmap Linear
},
// Blend Mode
blendMode: {
disableAlpha: false,
},
// Depth Writes
depthWrites: {
enable: false
}
};
