SKETCH: an interface for sketching 3D scenes
SIGGRAPH '96: Proceedings of the 23rd annual conference on Computer graphics and interactive techniquesPages 163–170https://doi.org/10.1145/237170.237238Sketching communicates ideas rapidly through approximate visual images with low overhead (pencil and paper), no need for precision or specialized knowledge, and ease of low-level correction and revision. In contrast, most 3D computer modeling systems ...

Optimal Transport Approximation of 2-Dimensional Measures
SIAM Journal on Imaging Sciences (SJISBI), Volume 12, Issue 2Pages 762–787https://doi.org/10.1137/18M1193736We propose a fast and scalable algorithm to project a given density on a set of structured measures defined over a compact 2D domain. The measures can be discrete or supported on curves, for instance. The proposed principle and algorithm are a natural ...
