从一系列的点中,创建一个平滑的二维样条曲线。内部使用[page:Interpolations.CatmullRom]来创建曲线。
// 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 );
points – 定义曲线的[page:Vector2]点的数组。
共有属性请参见其基类[page:Curve]。
定义这一曲线的[page:Vector2]点的数组。
