Purpose of this Blog

This blog intends to be an evolving tutorial on how to hand-draw spherical perspectives and VR panoramas.

I have written a couple of papers (*) on this subject, but these are far too mathematical for the average artist/urban sketcher, so the purpose of this blog is to make it simple without dumbing it down. Artists are not dumb and they are not well served by teaching methods that hide the complexity of things. What is needed is time and a careful use of language. Also, the reader's patience, but that's not my part of the deal.

Here is my strategy: because I am too busy (teach, research, draw, live!) for long posts, I'll make this fragmentary, and, over time, I'll edit it into a coherent whole. Further, I'll start very simple and I'll refine it as we go along, by revisiting each subject and explaining it in ever more detail: spiraling up!

Let's see if this works!

First: What is a VR panorama anyway?
