Three.js中如何实现模型对象角度旋转

这篇文章主要介绍了Three.js中如何实现模型对象角度旋转，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

model.rotation.x = -Math.PI / 4;

model.rotation.z = Math.PI / 4;

model.rotation.y = Math.PI / 2;

function rotateAroundWorldAxis(object, axis, radians) {

let rotWorldMatrix = new THREE.Matrix4();

rotWorldMatrix.makeRotationAxis(axis.normalize(), radians);

rotWorldMatrix.multiply(object.matrix);

object.matrix = rotWorldMatrix;

object.rotation.setFromRotationMatrix(object.matrix);

}

//调用方式，设置x、y、z轴的旋转

let xAxis = new THREE.Vector3(1, 0, 0);

let yAxis = new THREE.Vector3(0, 1, 0);

let zAxis = new THREE.Vector3(0, 0, 1);

//模型、旋转轴和旋转角度（弧度）

rotateAroundWorldAxis(model, xAxis, Math.PI / 8);

// Three.js r49之前:

object.rotation.getRotationFromMatrix(object.matrix, object.scale);

// Three.js r59之前:

object.rotation.setEulerFromRotationMatrix(object.matrix);
