Abstract

Anamorphic art uses perspective and mirrors to view a distorted image or sculpture in the correct way. Normally, making anamorphic art is a difficult task where errors can easily occur, since the artist has to create the image while thinking of their desired perspective. So, for centuries anamorphic art has been relegated to a curiosity. In recent years interest in the topic has been renewed and various papers have been published on anamorphic art. One such paper [L. Pratt, A. Johnston, and N. Pietroni, 2023] has advanced the creation of anamorphic sculptures by computer simulation to work with free-form 3D shapes as well as reflective and refractive materials. However, the paper does not consider light sources or normals, which can lead to odd shadows or lighter areas being introduced to models where it is not desired. Our project expands on the original project by developing a simplified version with limited reflection depth and adding lighting. We experiment with multiple approaches to solve this problem. We conclude that there are exact solutions for some specific cases, but that an approximation by minimizing the angle between deformed normals and what they should be is the best, most general solution. However, due to the approximation, there remain issues with lighting to be resolved.
