eulerAnglesFromMatrix
Functions
- coeff(mat4, row_index, column_index) ⇒
number - eulerAnglesFromMatrix(res, m4, a0, a1, a2)
\returns the Euler-angles of the rotation matrix \c *this using the convention defined by the triplet (\a a0,\a a1,\a a2)
Each of the three parameters \a a0,\a a1,\a a2 represents the respective rotation axis as an integer in 2. For instance, in: \code Vector3f ea = mat.eulerAngles(2, 0, 2); \endcode "2" represents the z axis and "0" the x axis, etc. The returned angles are such that we have the following equality: \code mat == AngleAxisf(ea[0], Vector3f::UnitZ()) * AngleAxisf(ea[1], Vector3f::UnitX()) * AngleAxisf(ea[2], Vector3f::UnitZ()); \endcode This corresponds to the right-multiply conventions (with right hand side frames).
The returned angles are in the ranges [0:pi]x[-pi:pi]x[-pi:pi]. NOTE: ported from Eigen C++ library
