Rhino3dPortugal 2013 and Rhino3dPortugal Masterclass identity for 2013. Every cover and poster image is based on a parametric definition that defines random points in canvas based on squared shapes generating the main grid for the image. After that, behind the grid, we use another definition of a raster delaunay triangulation to decompose the chosen image. So the same image input can give several different types of behing image. So every cover and poster is infinite. Everytime a new cover is need we use the two definitions to generate it. Parametric design.
