Hi there, I'm Boris!

I'm the founder of VGC, a startup based in Lyon, France.

I like to create all sort of things, and give them life :-)

Vector Graphics Animation with Time-Varying Topology

Boris Dalstein, Rémi Ronfard, Michiel van de Panne

ACM Transactions of Graphics, 34, 4 (SIGGRAPH 2015)

[ PDF ] [ BibTeX ]

We introduce the Vector Animation Complex (VAC), a novel data structure for vector graphics animation, designed to support the modeling of time-continuous topological events. This allows features of a connected drawing to merge, split, appear, or disappear at desired times via keyframes that introduce the desired topological change. Because the resulting space-time complex directly captures the time-varying topological structure, features are readily edited in both space and time in a way that reflects the intent of the drawing. A formal description of the data structure is provided, along with topological and geometric invariants. We illustrate our modeling paradigm with experimental results on various examples.
