three.js SplineCurve

从一系列的点中,创建一个平滑的二维样条曲线。内部使用Interpolations.CatmullRom来创建曲线。

代码示例

// 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 );

构造函数

points – 定义曲线的Vector2点的数组。

属性

共有属性请参见其基类Curve。

.points : Array
