Illustrated Interactive Panoramas
A unique method for telling an immersive story & a new way to enjoy hand drawn imagery.



Navigating the four point perspective

The earth is spherical. On a traditional map, the curved surface of the earth is displayed on a flat plane. In order to do this one needs to flatten the globe. Compare it to ‘cutting’ open the earth from top to bottom and then stretching out the top and bottom.

Equirectangular projection, the projection I most often use for my illustrated panoramas, is similar to the projection used for maps. The north and south poles are stretched to a line across the full width of the map. In reality they are a single point on the surface of the globe. This is why Antarctica and Greenland appear huge.

My drawings are often based on fisheye photos, ‘stitched’ together to form an 360x180 degree equirectangular image. Lately I've been using a Ricoh Theta S, an ‘instant’ panorama camera. No stitching needed.

The point in the ceiling or air directly above the camera (zenith) is just as the north pole stretched into a line. The same applies to the soil (nadir) and the South Pole.

The distortions, here mostly noticeable in the ground plane are a direct result of the 360x180 degrees perspective of the image.

Regular linear perspective rules don't apply in a panorama drawing. Instead of one vanishing point there are multiple. Whenever I draw a 'freehand' panorama I use a 'four point perspective grid' to figure things out.

From an equirectangular image, lots of other projections can be calculated. The cube projection, for instance, can be useful for complex panoramas with lots of detai. It’s perspective is slightly easier to navigate and (literally) cuts up the process. There is a disadvantage though as it involves lots of post processing work. The little planet projection is pretty useless but a lot of fun.

Tessa Schlechtriem started creating illustrated panoramas as a personal project (formerly aWorldaWeek), just for her own pleasure. While drawing her first panoramas she discovered how much is possible.
