Free-form sketching with variational implicit surfaces
With the advent of sketch-based methods for shape construction, there's a new degree of power available in the rapid creation of approximate shapes. Sketch [Zeleznik, 1996] s...

Shape Transformation Using Variational Implicit Functions
Traditionally, shape transformation using implicit functions is performed in two distinct steps: 1) creating two implicit functions, and 2) interpolating between these two functio...

Restoration of Curved Document Images through 3D Shape Modeling
In this paper, we address the problem of discovering the 3D shape of a book surface from the shading information in a scanned document image. This shapefrom-shading problem is cha...

Real-Time Ray-Casting and Advanced Shading of Discrete Isosurfaces
This paper presents a real-time rendering pipeline for implicit surfaces defined by a regular volumetric grid of samples. We use a ray-casting approach on current graphics hardwar...

Pyramid Coordinates for Morphing and Deformation
Many model editing operations, such as morphing, blending, and shape deformation, require the ability to interactively transform the surface of a model in response to some control...
