Holger Lippmann describes a part of his work as digital painting. What distinguishes digital painting from traditional painting on canvas or paper? We need to distinguish between two categories of digital painting. The first includes works created on the computer with ready-made graphic tools like virtual paint brushes or pens, in something like the way that non-digital pictures are created on paper or canvas. David Hockney’s painting of a sunflower on an i-pad is an example of this. The second category includes works using computer generation, in which programs coded by the artist continually produce new aesthetic concepts as images or animations. Every execution of the software creates new works within the pre-defined boundaries of the system. This process can be called generative painting.
