When using the rotation matrix, premultiply it with the coordinates to be rotated (as opposed to postmultiplying). The default order for Euler angle rotations is "ZYX". example rotm = eul2rotm(eul,sequence) converts Euler angles to a rotation matrix, rotm. The Euler angles are specified...
Euler angle和rotation matrix之间的转化其实上文提过,代码直接照搬上述公式即可。 因为所有的transform,无论是旋转还是平移,最终都要变成4x4矩阵代入到每个vertex的计算当中去,因此quaternion和matrx44之间的转换经常用到,所以先讲quaternion和matrix4x4之间的转化方法。 quaternion->matrix44 先上公式 M_{q} = \begin{...

Y and X axes. These angles are called Euler angles or Tait–Bryan angles. In the original Euler angle formulation, a rotation is described by successive rotations about the Z, X and again Z axes ( or for that matter Y-X-Y, or Z-Y-Z ). When the rotation is specified as rotations ...
eul = rotm2eul(rotm) converts a rotation matrix, rotm, to the corresponding Euler angles, eul. The input rotation matrix must be in the premultiply form for rotations. The default order for Euler angle rotations is "ZYX". example eul = rotm2eul(rotm,sequence) converts a rotation matr...

But molecules often contain rotations axes at some cockeyed angle, and we now have to learn how to deal with that. We will show two ways, the Euler rotation matrix (this chapter) and the Lie rotation matrix (next chapter).doi:10.1007/b13137_11William Martin McClain...
2. The output angles may become discontinuous if the rotation of the body goes through the singularity of the selected Euler angle rotation sequence. For classical (repeating) sequences the singularity is atsinθ2=0. For non-classical (non-repeating) sequences the singularity is atcosθ...
