Abstract
I present a diffusion based shape interpolation method which is applicable to 2D and 3D surfaces. As input, 2D shapes are represented as diffusion curves, the 3D shapes are simply 3D meshes. The algorithm generates an exact Voronoi diagram of two surfaces along with a distance map, both are stored as textures for further manipulation and lookup. The Voronoi diagram is used as starting point for the iterative color diffusion. After the diffusion step, an isovalue can be applied to the resulting texture. By varying the isovalue, different intermediate surfaces between the two input surfaces arise. In 2D, Diffusion Curves [3] are used as input, whereas in 3D, textured surface meshes as used. This shape interpolation method is applicable to every kind of shape that can be represented by diffusion curves or 3D surface meshes.Additional Files and Images
