Conical Anamorphic Projection of Photographic Images

This Demonstration explores the anamorphic projection of rasterized photographic images.
Each image is divided into a set of square cells. Each cell is then mapped as a polygon with the same color as the original cell in the photograph.
The conical anamorphic projection of a point at as seen from infinity in a conical mirror with opening angle and base radius 1 is given by the mapping .
The central image is what you see in a conical mirror placed with its base covering the central black circle and the eye at infinity above the top of the cone. Without the mirror, the image is unrecognizable.

Snapshot 1 shows how the different cells of a simple 8×8 raster are projected.
Snapshots 2 and 3 are projections of images divided in a raster of 48×48 cells.
