What steps should I follow in three.js to generate a sturdy ellipse and then apply a custom color fill to it?

As a newcomer to three.js, I've written some code to create a linear ellipse. Now, my goal is to achieve a solid color-filled ellipse instead.
  Additionally, I'm curious to learn how I can implement dragging functionality for the solid ellipse once it's generated.

var curve = new THREE.EllipseCurve(
0,  0,            // ax, aY
2, 16,           // xRadius, yRadius
0,  2 * Math.PI,  // aStartAngle, aEndAngle
false,            // aClockwise
0                 // aRotation
);

//ellipse
var path = new THREE.Path( curve.getPoints( 50 ) );
var geometry = path.createPointsGeometry( 50 );
var material = new THREE.MeshBasicMaterial( { color : 0x59d1c1} );
var ellipse = new THREE.Line( geometry, material );
scene.add(ellipse);

Answer №1

To create ellipses in Three.js, you can utilize the THREE.Shape and THREE.ShapeBufferGeometry classes. Below is a sample code snippet demonstrating how to achieve this:

var path = new THREE.Shape();
path.absellipse(0,0,2,16,0, Math.PI*2, false,0);
var geometry = new THREE.ShapeBufferGeometry( path );
var material = new THREE.MeshBasicMaterial( { color: 0x59d1c1} );
var ellipse = new THREE.Mesh( geometry, material );
scene.add(ellipse);
