You can think of it as a rendering engine. var camera = new THREE.PerspectiveCamera(75,window.innerWidth/window.innerHeight) Recall from Chapter 2 the pages of code it took to create the shape and texture map data for a simple cube using WebGL buffers, and then it required yet more. Let’s set it to 75, next is the aspect ratio, we’re going to use current width divided by height. What we are going to look at through this article is Build a Three.js 3D Cube With Different Textures and Colors in Browser Using HTML5 & Javascript We will. So the first parameter of the camera is the field of view, basically it’s the width of the perception angle. For orthography camera, you’ll see an isometric view of specified angle with no perspective. For most of the time, we’re going to stick with perspective which is a normal camera type where you will see closer object bigger and smaller when they’re away. Next we need to setup the camera, There are perspective and orthographic cameras. Scene is like a universe where we can add objects, camera and lights etc. Setting Up Sceneįor every project, First thing we need to do is to create a scene. Here is the bare minimum you need to render something onto a texture in Three. They always look cool in 3D: const torusGeometry new THREE. This time we'll add a torus, or donut shape. Three.js has more built-in geometries, so let's add another shape to the scene. There are a lot of examples out there on how to do this that tend to be embedded in more complicated effects. The BoxGeometry constructor takes three arguments: the width, height, and depth of the cube. If not, check out How to Learn Three.js for Game Development.

To show you the ideas of fundamental steps to create an animating 3D object with three.js, we’re going to add a spinning cube to an empty webpage. Note: This tutorial assumes you have some basic familiarity with Three.js.
