An Anaglyph is the name given to the stereoscopic 3D effect achieved by means of encoding each eye's image using filters of different colors, typically red and cyan. Anaglyph 3D images contain two differently filtered colored images, one for each eye. When viewed through the "color-coded" "anaglyph glasses", each of the two images reaches one eye, revealing an integrated stereoscopic image. The visual cortex of the brain fuses this into perception of a three-dimensional scene or composition. (Wikipedia)

With Microsoft Excel, students will create their own anaglyph of an object made of vertices and straight lines. Adding scrollbars, it is possible to animate the final anaglyph.

Videos showing each step of the project are available on YouTube, channel Anaglyph Project.

This project has been inspired by  “Les stéréogrammes”, an activity created by Vincent Papillon and François Trottier (Collège Jean-de-Brébeuf).
