<h2>代码示例</h2>
|
|
|
|
<code>
|
|
// Create a sine-like wave
|
|
const curve = new THREE.SplineCurve( [
|
|
new THREE.Vector2( -10, 0 ),
|
|
new THREE.Vector2( -5, 5 ),
|
|
new THREE.Vector2( 0, 0 ),
|
|
new THREE.Vector2( 5, -5 ),
|
|
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 splineObject = new THREE.Line( geometry, material );
