u_anipoints

points which move on the Riemann sphere or an object on the sphere at each update cycle

f uAniPoint() ...

factory function returns instance of a class represetning a point which moves in relation to a given geometric object of the Riemann sphere at each update cyle

constructors:
uAniPoint (float,<float> )
uAniPoint (<theta = float> <,phi= float> )
point of the Riemann sphere that moves as a spiral on the sphere from its initial point to its antipodal point, with the initial point determined by given polar coordinates, in radians
uAniPoint (zcircle <,float> )
point of the given spheric section of the Riemann sphere that moves along the spheric section at each update, with its initial position determined by optinal float argument, in radians
