Stumptown Preview #5: Curvilinear Grids

More excerpts from the demonstration talk I'm giving tomorrow at Stumptown:

David Chelsea is listening to:

A Hard Day's Night by The Beatles

I worked out the construction of curvilinear perspective years before I did my first perspective book, but all things curvilinear wound up on the cutting room floor that time. Now, 14 years later, my new book, Extreme Perspective!, includes chapters on curvilinear perspective (which comes in two main types, fisheye and cylindrical), and the accompanying DVD includes dozens of curvilinear grids for those who don't have the time or inclination to do the construction themselves.

Each grid appears in two versions: a cubic lattice with tiled columns, and a simpler pattern of a cube with squared-up faces.

While many artists will likely use the grids as a background layer in Photoshop, I prefer to print out pale blue versions and sketch over them in pen and ink.

Perhaps my favorite grid of all is this "Oblique Cylindrical" which includes all six vanishing points in a single view.

Working over it results in delightfully loopy panoramas like this one:
