Résumé
There are only a dozen representations of fish in parietal art in the world. The one in the Fish Shelter is said to be the oldest of all. This fish figure is so rare and precious that it was almost cut up and sold. This engraving is complex to understand, many details leave researchers perplexed. A new survey campaign, the first in 30 years, was conducted between 2016 and 2019 to obtain a very detailed geometric model of the shelter, fish and other archaeological evidence present. Just for fish engraving, the photogrammetric model has a resolution of 16 polygons per square millimeter, which enables us to digitally investigate every detail. For this article, we will show how we use Grasshopper, a parametric software well known in architecture, to create two types of maps: a depth map and an incidence map. These two pieces of information are essential to understand how the engraving was made.
