◆ 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.

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)

w	Vector about which to rotate.
A	$\frac{\sin \theta}{\theta}$
B	$\frac{1 - \cos \theta}{\theta^2}$
R	Matrix to hold the return value.

Detailed Description

Classes

Typedefs

Functions

Variables

Simple intersection operations, relying basically on geometrical operations.

Angle retrieval methods. Methods which use TSegments will automatically use TLines' implicit constructors.

Creation of lines from poses.

Other line or plane related methods.

Projections

Polygon intersections. These operations rely more on spatial reasoning than in raw numerical operations.

Other intersections

Distances

Bound checkers

Creation of planes from poses

Linear regression methods

Miscellaneous Geometry methods

SLERP (Spherical Linear Interpolation) functions
