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...
Quaternion to Euler angle converter?pmazzoni Sat, 10/07/2023 - 01:05 pm I would like to write a conversion function from (unnormalized) quaternions to Euler angles representing a 3D rotation (from accelerometer data). Does anyone have such a routine already written and is willing to share ...

On this plane lines of common orientation are diagonal lines, that is rotation around 0,1,0 axis are given by angle = heading+bank. Similarly for the south pole. Example we take the 90 degree rotation from this:to this: Asshown herethe quaternion for this rotation is: (0.7071+ i 0.7071...
