rotateTo

rotateTo是Yuka js库中的Quaternion类的方法,用于将当前四元数旋转到目标四元数。

语法

rotateTo(target: Quaternion, step: number): Quaternion

参数

  • target:目标四元数,类型为Quaternion。
  • step:每一帧的旋转步长(0~1之间的值),类型为number,默认值为0.05。

返回值

旋转后的四元数,类型为Quaternion。

描述

使用该方法可以将当前四元数旋转到目标四元数,可以设置每一帧旋转的步长,从而平滑的旋转过渡。

示例

const currentRotation = new Quaternion(0, 0, 0, 1);
const targetRotation = new Quaternion(0.707, 0, 0, 0.707);

function animate() {
  // 旋转到目标四元数
  currentRotation.rotateTo(targetRotation);

  // 更新对象的旋转
  object.rotation.setFromQuaternion(currentRotation);

  requestAnimationFrame(animate);
}
animate();

备注

  • 旋转步长越小,旋转的过渡越平滑,但可能会增加计算量。
  • 如果当前四元数与目标四元数的距离很近,则不需要进行任何旋转操作。
