#yyds干货盘点#three.js中Vector3向量的四则运算

1.代码

const v3 = new THREE.Vector3(5, 10, 15)

// 1.加法
v3.add(new THREE.Vector3(10, 10, 10))
console.log('v3', v3)

v3.addScalar(20)
console.log('v3', v3)

// 2.减法
v3.sub(new THREE.Vector3(2, 3, 4))
console.log('v3', v3)

v3.subScalar(10)
console.log('v3', v3)

// 3.乘法
v3.multiply(new THREE.Vector3(5, 10, 15))
console.log('v3', v3)

v3.multiplyScalar(10)
console.log('v3', v3)

// 4.除法
v3.divide(new THREE.Vector3(2, 3, 4))
console.log('v3', v3)

v3.divideScalar(10)
console.log('v3', v3)
