      I’m not sure what major steps are missing. The buildings are drawn conforming the guidelines of the sphere.

        Even after your explanation of step 2, I’m not sure it’s really a single step. 3 could probably be broken down, too. Maybe 8-10 steps total instead of four.

        It’s a cool graphic and a cool approach though. It explains what you’re doing, so I can understand it. But it doesn’t really give me small enough steps, so I could do it.

    How do you draw step 2? Centre a pair of compasses at points between vp1 and vp4 and sweep arcs between vp2 and vp3?

      If you’ll excuse the crudeness of the page, I whipped this up quickly using a circular stencil probably too small for this. But this is a quick and dirty way that doesn’t technically need anything more specialized than a ruler since you can make the initial circle with it.

      Make your x and y lines through the center. Then you can make 45 degree lines off of those and measure marks, and then use those as ellipse guides. Then keep measuring out guides for your ellipses.

      Again, this won’t be mathematically perfect ellipses since you have to draw the lines freehand, but for perspective guides they should work. More specialized tools, or just doing to digitally will simplify the process.

        I see, yes. I like the approach, the perspective is very nice. Unfortunately, it’s not so easy with basic tools since I realise now that the arcs are not circular so compasses will not work.
