In JavaScript, geometries are used to create and define shapes in Three.js. An instance of the Three. Geometry class is geometry, and faces and vertices define a shape. The position of points in space is defined as a vertex, and a face represents a shape's surface. 


One of the powerful game libraries for creating web-based games is the Three.js library in JavaScript. It is a cross-browser JavaScript library and API designed to help us build and display 3D animations in the browser using webGL - anything from simple three-dimensional patterns to photorealistic and real-time scenes. We can also build simple and complex three-dimensional geometrics, animate, and move objects through a lifelike scene, and more on the three.js library. This library enables us to apply textures and materials to our objects. It also provides various light sources to illuminate our scene, advanced postprocessing effects, custom shaders, etc. We can load objects from three-dimensional modeling software for our game or application. 


Here is an example of how to create a three.js geometry earth's surface: 

Fig : Preview of the output that you will get on running this code from your IDE.

Code

In this solution we're using React, Nodejs and three.js libraries.

How can you create a three.js geometry that is equivalent to looking over the earths surface?

Dependent Libraries : 
var geometry = new THREE.SphereGeometry(3, 16, 8, 0, Math.PI * 2, 0, Math.PI/4);

var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera( 75, window.innerWidth/window.innerHeight, 0.1, 1000 );

var renderer = new THREE.WebGLRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );

var geometry = new THREE.SphereGeometry(3, 16, 8, 0, Math.PI * 2, 0, Math.PI/4);
var material = new THREE.MeshBasicMaterial({
        color: 0xff0000,
        wireframe: true
    });
var sphere = new THREE.Mesh( geometry, material );
scene.add( sphere );

sphere.position.y -= 3;
camera.position.z = 4;
camera.rotation.x -= Math.PI / 9

var render = function () {
  requestAnimationFrame( render );

  renderer.render(scene, camera);
};

render();

Instructions

Follow the steps carefully to get the output easily.

  1. Install the Node.js and React on your IDE.
  2. Create React Application using npx create-react-app foldername.
  3. cd foldername.
  4. Open the folder in Visual Studio Code IDE.
  5. Copy the code using "copy" button above and paste it in app.js file(remove the earlier code from app.js).
  6. Cut the script tag which is present at end of the code and paste it in index.html file(remove the earlier code from index.html if present).
  7. Import three.js library as import * as THREE from 'three'.
  8. Add export default statement as 'export default render'.
  9. Open the terminal from Visual Studio Code.
  10. npm start to run the file.


I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.


I found this code snippet by searching for 'create three.js geometry earth surface' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in Visual Studio Code 1.73.1.
  2. The solution is tested on node v18.12.1 and npm v8.19.2.
  3. React version-18.2.0.
  4. three version-0.148.0.


Using this solution, we are able to create a three.js geometry earths surface with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to create a three.js geometry earths surface.
