How to find the full argument list of a built-in function?
My first use of Sage is utilizing its fantastic 3D plotting capabilities with Jmol. I am visualizing 3D curves from data points via line3d() and than using the show() method on the graphics objects. line3d? and show? give a short list of arguments such as color, thickness, radius for line3d, and frame for show. I know there are many more arguments, for example corner_cutoff for smoothing, but I only stumble upon them while browsing the Sage documentation. So far, I haven't found a source to list all the arguments for line3d or similar functions. I understand that these are Python wrappers and I tried things like dir() but I could not find more information than that given by line3d? Where am I going wrong? I am quite sure there are arguments controlling background color, the way frames and axes are labeled, etc. How can I find them? -Thanks.
