three.signal-line v1.1.8

Three.Signal-Line

three.signal-line is a JavaScript package that provides a signal line component for the popular 3D rendering library, Three.js. It allows you to create animated signal lines in your Three.js scenes with customizable colors, speeds, sizes, and more.

Features

• Animated Signal Lines: Create visually appealing animated signal lines in your Three.js scenes.
• Customizable Options: Control the appearance and behavior of signal lines with customizable options such as color, speed, size, opacity, and texture.
• Backward Movement: Choose whether the signal lines move forward or backward along their paths.
• Texture Support: Apply textures to signal lines for enhanced visual effects.
• Smooth Animation: Signal lines smoothly transition between points, creating fluid animations.
• Easy Integration: The package integrates seamlessly with Three.js, making it easy to incorporate signal lines into your existing Three.js projects.

The package also have nice some things:

• Backwards compatibility for Node.js-style (CommonJS) imports
• Both strict and flexible typescript configurations available
• Collocated, atomic, concurrent unit tests with AVA
• Source-mapped code coverage reports with nyc
• Configurable code coverage testing (for continuous integration)
• Automatic linting and formatting using TSLint and Prettier
• Automatically check for known vulnerabilities in your dependencies with nsp

Installation

You can install Three.Signal-Line via npm or yarn:

npm install three.signal-line

or

yarn add three.signal-line

Usage

To use Three.Signal-Line, you need to have Three.js already set up in your project. Once you have imported the required dependencies, you can create a signal line by providing the necessary options and a line geometry:

import { SignalLine } from 'three.signal-line';

// Create a Three.js scene
const scene = new THREE.Scene();

// Create options for the SignalLine
const options = {
  linePath: [
    new THREE.Vector3(0, 0, 0),
    new THREE.Vector3(1, 1, 1),
    new THREE.Vector3(2, 2, 2),
  ],
  lineType: LINE_TYPE.NORMAL,
  materialOptions: {
    color: 0xff0000,
    opacity: 1.0,
    blending: THREE.NormalBlending,
    transparent: true,
    depthWrite: true,
    lineWidth: 2,
  },
  isDebug: false,
};

// Create a new SignalLine instance
const signalLine = new SignalLine(options, scene);

Sending Signals:

To sending signals you should pass signal options by using send method:

// Define the options for the signal
const options = {
  color: '#ff0000',
  speed: 200,
  size: 30,
  backwardMoving: false,
  opacity: 0.5,
  particleTexture: 'path/to/texture.png', // not required
}

signalLine.send(options);

Working with Labels:

You can add label by using public addLabel method:

// Define the options for the signal
const options = {
  textOptions: {
    color: "#ff0000",
    size: 2
  },
  position: "start",
  lookAtCamera: false
};

signalLine.addLabel(options);
