Pictorial Style
Transfer function between scene properties and a set of primitives with
attributes (color, color gradient, etc.) (Willats & Durand 2003)
Existing rendering methods coming from Computer Graphics (Hertzmann et al.
2001, Landes et al. 2013)

(http://oxygene-project.sourceforge.net/)
implementation of controllable design tools
First step toward a Cassini style
basis for analysis of cartographic practices
knowledge identification about styles/data representation
Forthcoming works on Cassini renderings
relief rendering: more perceived than realistic
data/scale/style interpolation between Cassini and contemporary maps
Evaluation of resulting Cassini-style maps
