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{...
在实时图形渲染领域,矩阵变换是执行物体位置、形状、光照以及摄像机方向等关键操作的基础手段。旋转变换,作为矩阵变换的一种特殊形式,是本文的主要关注点。本文将深入探讨旋转矩阵、欧拉变换和四元数变换的原理、转换关系和适用范围,而不涉及具体API的使用。旋转变换有三种主要表达形式:旋转矩阵、欧拉变换...

Here E denotes the ECEF frame and N denotes the local level wander-angle frame. The resulting DCM projects from N frame to E frame. If ``wan=0`` then the 2nd axis of N frame points to North. Parameters --- lat, lon : float or array_like with shape (n,) Latitude and...
