Let me expand the example a bit. We are given two points. We draw a line segment connecting the two points. Then we want to draw a circle with a diameter the line segment.
Certainly we need to compute the center and the radius of the circle. The standard way to do this with Sage is, as Travis described, to do some vector calculus. But an intuitive way (or an object-oriented way ?) is to get the necessary information from the line segment. Thus if L is the line segment, I do p = L.mid_point(); r = L.length() / 2. Then circle(p, r) will do the work.

Then we do L.draw() + C.draw(). This is an interesting idea. But this would make graphics module a dependency of Euclidean space module. By the way, the purpose of my original post is to ask whether providing the facility for the intuitive way of drawing (algorithmic drawing or object-oriented drawing, to invent a fancy term) is worth while or just waste of energy... -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
