Abstract
Catoptric anamorphosis is an image which seems to be distorted, but looks normal when observed from a specific point of view and indirectly via a reflective object. While some methods already exist that can create such images, they are limited in the amount of differently shaped reflective objects they support or they require you to obtain a 3D model of your object. We propose a new method, that can work with a reflective object of any shape and that requires minimal work from the user. After a suitable reference pattern is generated, the user can give a picture of both the reflective object and the pattern along with a picture of the reflection of the anamorphosis as input and the output is the corresponding anamorphosis. The results show that the method creates accurate catoptric anamorphoses for most differently shaped reflective objects. It is concluded that this method can help existing and new artists to create catoptric anamorphoses more easily while still offering the same features as older methods.
