The following conversation was re-published with permission from the brand-new publication Spheres by Swiss graphic designer Philippe Karrer. Rafaël Rozendaal and Jürg Lehni discuss their shared interest in vector graphics, which are based on mathematically-defined geometrical entities such as lines, circles, and points, in contrast with more commonly used bitmap graphics, in which values are assigned to grids of pixels.
Rafaël Rozendaal: Vectors are based on mathematical equations. The equations are perfect. No matter how we try, we can never render a perfect circle in any medium. And even if we did, our imperfect eyes would not be able to register its perfection. Do we have to accept that such shapes can only exist in our mind?
