Research

My interests in computer graphics are related to art practices and history, geometry, and the psychology of visual perception. One theme in computer graphics tries to reproduce the appearance of the world: it uses models based on physics to simulate the interaction of light with matter. Another theme, non-photorealistic rendering, seeks to imitate the practice of painters, who make less realistic but more true depictions of the world. The second interests me, but imitating the actions of artists, I want to understand their representational practices, using them to enhance computer graphics.

For example, I am investigating the interaction between two and three dimensions in the process of depicting the world on an image. Specifically, looking into how perspective was used in Renaissance painting and how it was integrated with strong image plane composition techniques I built a program that relies on those artistic practices. I also created a mathematical formalism which uses 2D matrices to calculate the geometry involved. Another example is that at the difference of computer graphics modelling, artists do not create faces as collections of triangles. Instead starting from a depiction of a 3D primitive, they add details, displacements, on its surface.
