This Demonstration explores the anamorphic projection of rasterized photographic images.

[more]

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.

Snapshots


Details

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.
