I produced these diagrams as a way of better visualizing Carnelian's entry into the Wheel in The Chosen. They are indicative of the exhaustive preparatory work that I used to do and which was strongly influenced by my working method in my, then recent, previous career as a designer of computer games. Each diagram is an accurate perspective drawing.

The first diagram is what Carnelian can see as he approaches the gatehouses of the Wheel. The blue square is the projection plane. Note the Sacred Wall of Osrakum showing its size and the position of the sun and the shadow which it casts on the road on which Carnelian is riding.

The second diagram shows the view looking back when Carnelian is halfway across the bridge spanning the moat that runs around the Wheel.

The third diagram shows a view from the same spot looking down at the moat.

Gradually I moved away from such excessive preparatory work. It was simply over the top. My research became increasingly light footed as I gained experience in the writing process. These days my reasearches are much more focused and lean.
