The [page:Layers layers] that the camera is a member of. This is an inherited property from [page:Object3D]. Objects must share at least one layer with the camera to be seen when the camera's viewpoint is rendered. [property:Matrix4 matrixWorldInverse] This is the inverse of matrixWorld. MatrixWorld contains the Matrix which has the world ...
The most common camera in three.js and the one we've been using up to this point is the PerspectiveCamera. It gives a 3d view where things in the distance appear smaller than things up close. The PerspectiveCamera defines a frustum. A frustum is a solid pyramid shape with the tip cut off. By name of a solid I mean for example a cube, a cone, a ...
Camera Video Lecture. Description. There are several types of Cameras in Threejs. In this video we will experiment with the Perspective and the Orthographic cameras. The camera properties describe a Frustum which are the dimensions inside the scene that will be rendered. Perspective Camera

Let's figure out how we can make a 3D model we build with three.jsinteractive – when we click on it, the camera moves to put the clicked object to the center of the screen, like this: I currently need this for a project I'm working on, Nuffshell, a social network and collaboration tool based on mind maps. For this part of my series, however, I'm no...
As a first step, I'm going to set up my basic 3D scene that shows four colored cubes, for now, without interactivity or animation.
Me need to be able to click on 3D objects to tell the camera where to move to. To achieve this, I'm adding a dependency to the npm package three.interactiveto my project. This library allows us to add event listener to our 3D objects, just like with HTML DOM nodes. At the beginning of my index.js, I'm adding an import statement to use three.interac...
Now let's actually move the camera to the position of the cube that was clicked. This is actually pretty straightforward – I just have to update the camera's position to match the X/Y coordinates of the cube that was clicked. Here's the updated forloop that creates the cubes: Note that while the camera's X and Y coordinates change, the Z coordinate...
So far, when a cube is clicked, the camera jumps to the cube's position immediately. This is a step in the right direction, but actually want the camera to move over to the cube's position in a smooth motion (technically, this is called “panning”). In short, we want to add some proper animation magic!
For creating smooth motions in animations, we use a technique called inbetweening, or “tweeting”, in short. This technique is as old as animating itself, it was used by the artists making Snow Whitein the 1930s, just as it is used by the artists making animations today. The basic idea is that you have a start and end state or something to animate (...
To make our camera move smoothly, we need to use tweening. Like interactivity, three.js does not provide this out of the box. We're going to have to add another npm package dependency to our project: @tweenjs/tween.js. This library is not specifically for use with three.js. You can use it any time something should be changed over a period of time. ...
Here's the final version of our project: When you click on a cube, the camera pans smoothly over to its position – nice!
This tutorial is part of my project diary. I'm building social media network and collaboration tool, based on mind maps. I will continue to blog about my progress in follow-up articles. Stay tuned!

As we saw earlier, the PerspectiveCamera class needs some parameters to be instantiated, but we didn't use all the possible parameters. Add the third and fourth parameters: const camera = new THREE.PerspectiveCamera(75, sizes.width / sizes.height, 1, 100) You should get the same result but let's talk about those parameters in detail.
The pattern for instantiating an orthographic camera in three.js is: var camera = new THREE.OrthographicCamera( width / - 2, width / 2, height / 2, height / - 2, near, far ); where width and height are the width and height of the camera's cuboid-shaped frustum measured in world-space units.
