In wagnius-GmbH/slvwagner: All Stuff that I`m Missing

3d rotation matrix

Description

Calculates a 3D rotation matrix for a given rotation axis x(unit vector) and an angle angle. The rotation will be applied by the right hand rule.

Usage

math_rot_matrix3d(x, angle)

Arguments

x	unit vector c(x1,x2,x3) defining the rotation axis
angle	in radiant
