Mastering Three.JS: Unlocking the Secrets of "Circle Geometry" and Testing its Functionality

Recently, I came across THREE.js and managed to make it work successfully. This is how I included it in my HTML:

<script src="https://rawgithub.com/mrdoob/three.js/master/build/three.js"></script>

I am now interested in accessing the "extras". Specifically, I'd like to use CircleGeomtry. Although I checked their documentation, I'm uncertain about how to implement it in my HTML.

According to their documentation, this is what's mentioned:

src/extras/geometries/CircleGeometry.js

Do I need to download it? Or can I reference it similar to the way I did above?

Answer №1

Looking through the source code provided at the URL for three.js, you can find that the CircleGeometry is already part of the file.

THREE.CircleGeometry = function ( radius, segments, thetaStart, thetaLength ) {
    THREE.Geometry.call( this );

    radius = radius || 50;

    thetaStart = thetaStart !== undefined ? thetaStart : 0;
    thetaLength = thetaLength !== undefined ? thetaLength : Math.PI * 2;
    segments = segments !== undefined ? Math.max( 3, segments ) : 8;

    // snipped...
}

This means there's no need to add any extra scripts. You can simply create your circle object.

var circleGeom = new THREE.CircleGeometry(10);

All the "extras" in three.js are already included in the distributed library. The library's source code is divided into multiple files for organizational purposes. However, when it comes to using the library on a webpage, all these files are combined into one for easy inclusion.
