In this workshop we will show how to use Dürer machines, both physical (made of thread) and virtual (made of lines) to create anamorphic optical illusions. We will do practical work on oblique anamorphosis and then briefly discuss curvilinear anamorphosis, as well as 3D anaglyphic anamorphoses, which can be seen with red-blue 3D glasses.

This talk may be had just for fun, with no special requirements, but it may be especially useful to teachers of descriptive geometry, since it uses othographic techniques to create enticing illusions that captivate young students and motivate them to learn the basics concepts of descriptive geometry.

I will also discuss how anamorphosis is - in my view - the foundational concept of conical perspectives (both classical and curvilinear) and is therefore a useful starting point for teaching and understanding them.
