<h2>Code Example</h2>
|
||
|
|
|
||
|
|
<code>
|
||
|
|
const curve = new THREE.QuadraticBezierCurve(
|
||
|
|
new THREE.Vector2( -10, 0 ),
|
||
|
|
new THREE.Vector2( 20, 15 ),
|
||
|
|
new THREE.Vector2( 10, 0 )
|
||
|
|
);
|
||
|
|
|
||
|
|
const points = curve.getPoints( 50 );
|
||
|
|
const geometry = new THREE.BufferGeometry().setFromPoints( points );
|
||
|
|
|
||
|
|
const material = new THREE.LineBasicMaterial( { color: 0xff0000 } );
|
||
|
|
|
||
|
|
// Create the final object to add to the scene
|
||
|
|
const curveObject = new THREE.Line( geometry, material );
