Visual representations are essential to explore and communicate an idea or a phenomenon.
Narrative storytelling for the infection phenomenon
Contributions:
- A novel sketch-based modeling method to design distributions of 3D shape, enabling the modeling of dense 3D environments such as biological tissues with fiber networks in which cells evolve;
- A solution for sketch-based animation, applicable to both 2.5D and 3D settings, that builds on standard schematic conventions in biology to allow the specification of motion and deformation;
- An interface for specifying and controlling temporal narrative scenarios, with a series of events triggered over time;
- A final user study with 11 expert biologists, enabling us to validate the relevance of our tool and to identify in which use cases 2.5D vs. 3D illustrations are the most relevant.

Analysis/Synthesis of sketched-based shape distribution
Contributions:
- a fine-to-coarse analysis method enabling to hierarchically cluster user strokes depending on their proximity in position, alignment and/or orientation, into a support structure hierarchy;
- a coarse-to-fine planar synthesis method through domain partitioning, based on the extracted hierarchy;
- a second synthesis method based on the same input that creates a 3D distribution of elements perceptually similar to the input sketch, and in which users can navigate.

Sketching evolving environments for architectural design
Contributions:
- A recursive solution for creating a 3D sketch by drawing on semi-transparent 3D canvases, themselves extruded from user’s strokes interpreted as footprints — with the associated visualization and editing tools;
- A method, based on local attraction to dense stroke regions, for enabling interactive navigation through the alternative designs that the nested sketch visually suggests. This navigation may not only drive displacement, but also free-form deformation of the nested 3D canvases carrying the user’s strokes.
