This monograph reviews both the theory and practice of the numerical computation of
geodesic distances on Riemannian manifolds. The notion of Riemannian manifold allows …

This paper presents an unpaired method for creating line drawings from photographs.
Current methods often rely on high quality paired datasets to generate line drawings …

Implicit surfaces (IS) are commonly used in image creation, modeling environments,
modeling objects, and scientific data visualization. In this article, we present a survey of …

We propose a method for reconstructing 3D shapes from 2D sketches in the form of line
drawings. Our method takes as input a single sketch, or multiple sketches, and outputs a …

Inside-outside determination is a basic building block for higher-level geometry processing
operations. Generalized winding numbers provide a robust answer for triangle meshes …

This article introduces a method for partial matching of surfaces represented by triangular
meshes. Our method matches surface regions that are numerically and topologically …

Realistic 3D facial generation based on Neural Radiance Fields (NeRFs) from 2D sketches
benefits various applications. Despite the high realism of free-view rendering results of …

Product designers extensively use sketching to reason and communicate about 3D shapes,
as documented in popular design sketching textbooks [Eissen and Steur 2008, 2011; Pipes …

Shape structure is about the arrangement and relations between shape parts. Structure-
aware shape processing goes beyond local geometry and low level processing to analyze …

Three-dimensional shape can be drawn using a variety of feature lines, but none of the
current definitions alone seem to capture all visually-relevant lines. We introduce a new …
