- Introduction of meschers, a mesh representation for impossible objects inspired by M.C. Escher's works.
- Meschers store 2D screen-space positions per vertex and depth differences per edge, differing from standard meshes.
- The representation is based on discrete exterior calculus, supporting geometry processing operations like smoothing and inverse rendering.
- Demonstrates the ability to perform inverse rendering to deform possible objects into impossible ones, matching target images.
- Highlights the potential of meschers in both computer graphics and understanding human visual perception.
