Hi,
I'd like to create a sphere with lines for longitudes and latitudes,
which basically is just a white sphere with thin black lines on horizon
and parallel to the horizon, and lines from north to south.
How would I do this?
I tried to apply a texture with a color map onto the surface of the
sphere, but the gradient is just a linear vector of x,y,z and not
a term (e.g. the angle phi cannot be used).
Another approach would be to mix the sphere with very flat and black
cylinders which are just a little big bigger than the sphere, but then
the sphere is not perfect anymore.
How could I get a sphere with those lines?
regards
Hadmut
