u_sliders

points pickable and movable constrained to the Riemann sphere or an object on the sphere

f uSlider() ...

factory function returns instance of a class representing points of the Riemann sphere that can be picked and moved on the sphere or constrained to an object on the sphere.

constructors:
uSlider (float,<float> )
uSlider (<theta = float> <,phi= float> )
point of the Riemann sphere that can be picked and moved constrained to the sphere and with initial position at the given spherical coordinates, in radians
uSlider (zcircle <,float> )
point of the given spheric section of the Riemann sphere that can be picked and moved constrained to the spheric section , with its initial position determined by optinal float argument, in radians
