PerspectiveCamera ( fieldOfView, aspectRatio, nearPlane, farPlane ) // Finally, set the camera's position in the z-dimension camera. Only objects // between those planes will be rendered in the scene // (these values help control the number of items rendered // at any given time) var nearPlane = 0.1 var farPlane = 1000 // Use the values specified above to create a camera var camera = new THREE. innerHeight // Specify the near and far clipping planes. Scene () Ĭamera: The camera determines the position from which viewers see the scene: // Specify the portion of the scene visiable at any time (in degrees) var fieldOfView = 75 // Specify the camera's aspect ratio var aspectRatio = window.
Scene: The scene contains all objects to be rendered: // Create the scene and a camera to view it var scene = new THREE. To get started with Three.js, one needs to provide a bit of boilerplate code with the three essential elements of a Three.js page: For a quick sample of the projects others have built with the library, check out the Three.js homepage. Using Three.js, one can build complex 3D environments that would take much more code to build in raw WebGL. Three.js is a JavaScript library that generates lower-level code for WebGL, the standard API for 3D rendering in a web browser. If you’re interested in creating something similar, feel free to check out the full code. In this post, I wanted to discuss how we used the amazing Three.js library to build a WebGL-powered visualization that can display tens of thousands of images in an interactive 3D environment : Some of those experiments have involved identifying similar images and visualizing patterns uncovered in this process. For the last year or so, Yale’s DHLab has undertaken a series of experiments organized around analysis of visual culture.
