Hello all, So I finally got the Andrew Loomis book for drawing heads. At the beginning ( going right back to basics! ) you start off with a sphere and mark the axis ready for constructing the rest of the head. I am struggling though because I am not sure exactly how you accurately find the axis lines on the sphere. I know roughly where they would go and can do an alright job ( I think ) with guess work, but I would like to be more accurate with these measurements, but I am not sure how. Is there a method or a way of finding the axis / slicing the sphere accurately or is it down to guess work?
I realise this seems like a novice question, but you have to ask to learn right?
Just a quick image of the paper next to me, it's not the best example as they are just doodles/ not even accurate circles but hopefully it gives you an idea what I am talking about if the text above made no sense.
I am not sure if it's actually marking the axis I am struggling with or more wrapping it around the sphere, knowing exactly the point it falls off at / you can see to. Am I making sense or talking gibberish?
