I would like to plot a sphere $x^2+y^2+z^2=4$ by revolving a circle $x^2+y^2=4$ with respect to diameter. The whole revolution process will be shown by animation. How can I do this?
For each step of the (discretized) revolution process you have to define a picture, and you will glue the pictures into an animation with the animate function. Since each picture corresponds to a range of longitudes, the easiest way to do this should be to use a representation of the sphere by it spherical coordinates, so, you can use the following:
