Item Repoussé: Automatic Inflation of 2D Artwork(The Eurographics Association, 2008) Joshi, Pushkar; Carr, Nathan A.; Christine Alvarado and Marie-Paule CaniWe describe a new system for the interactive enhancement of 2D art with 3D geometry. Repoussé creates a 3D shape by inflating the surface that interpolates the input curves. By using the mean curvature stored at boundary vertices as a degree of freedom, we are able to control the inflated surface intuitively and efficiently using a single linear system. Repoussé handles both smooth and sharp position constraints. Position constraint vertices can also have curvature constraints for controlling the inflation of the local surface. We show the applications of our system in font design, stroke design, photo enhancement and freeform 3D shape design.
