three.js 提供了两种三维旋转表达方式： 欧拉角 (euler) 和 四元数 (quaternion) 。 它们相比较使用 矩阵的方式 进行变换更加的节省存储空间和更方便的进行插值。 但是 欧拉角 (euler) 存在万向锁问题，配置可能失去一定的自由度所以都是使用在 四元数 (quaternion) 。 欧拉角 欧拉角需要指定x,y,z三个轴的角度和旋转的顺序。 Euler ( x, y, z, order ) 万向锁 问题：当三个万向节其中两个的轴发生重合时，会失去一个自由度的情形。 https://zh.wikipedia.org 正常状态：三个独立的旋转轴.

2022. 6. 30. · Quaternion in Three.js: there seems to be quite some changes between versions. From below, these are the codes works for R69. 1. Initialize a quaternion object with axis-angle. 2. "copy" to the mesh.quaternion. function. Well for smooth rotation you could try using the THREE.js quaternion.slerp() functionality, but to be honest using quaternions may be a bit gnarly for someone beginning in 3D. 1 Share. Two rotation quaternions can be combined into one equivalent quaternion by the relation: ′ = in which q′ corresponds to the rotation q 1 followed by the rotation q 2. (Note that quaternion multiplication is not commutative.) Thus, an arbitrary number of rotations can be composed together and then applied as a single rotation.. three.js 欧拉角和四元数. 这篇郭先生就来说说欧拉角和四元数，欧拉角和四元数的优缺点是老生常谈的话题了，使用条件我就不多说了，我只说一下使用方法。. 1. 欧拉角（Euler）. 欧拉角描述一个旋转变换，通过指定轴顺序和其各个轴向上的指定旋转角度来旋转.

2019. 7. 4. · var euler = new THREE.Euler(rx,ry,rz); var quaternion = new THREE.Quaternion(); quaternion.setFromEuler(euler); object.rotation.setFromQuaternion( quaternion ) However, the results are not what we expected. Could be an issue on our end. We’re trying to build a simple keyframe system to change position and rotation over time. rotationMatrix = rotmat (quat, 'frame') rotationMatrix = 3 × 3 0 This class represents a quaternion that is a convenient representation of orientations and rotations of objects in three dimensions Now, to get position after rotation, you multiply 1x4 matrix by 4x1 matrix, which is quaternion (Quadruple Notation) by position (x, y, z, w), where.
