◆ generateAxisBaseFromDirection()

template<class T >

CMatrixTemplateNumeric<T> mrpt::math::generateAxisBaseFromDirection	(	T	dx,
		T	dy,
		T	dz
	)

Computes an axis base (a set of three 3D normal vectors) with the given vector being the first of them ("X") NOTE: Make sure of passing all floats or doubles and that the template of the receiving matrix is of the same type!

If $ d = [ dx ~ dy ~ dz ] $ is the input vector, then this function returns a matrix $ M $ such as:

$M = \left( \begin{array}{c c c} v^1_x ~ v^2_x ~ v^3_x \\ v^1_y ~ v^2_y ~ v^3_y \\ v^1_z ~ v^2_z ~ v^3_z \end{array} \right)$

And the three normal vectors are computed as:

$v^1 = \frac{d}{|d|}$

   If (dx!=0 or dy!=0):

$v^2 = \frac{[-dy ~ dx ~ 0 ]}{\sqrt{dx^2+dy^2}}$

otherwise (the direction vector is vertical):

$v^2 = [1 ~ 0 ~ 0]$

   And finally, the third vector is the cross product of the others:

$v^3 = v^1 \times v^2$

Returns: The 3x3 matrix (CMatrixTemplateNumeric<T>), containing one vector per column. Throws an std::exception on invalid input (i.e. null direction vector)
