In this paper we introduce a new approach to the deformation of surface and raster models in two and three dimensions. Rather then deforming the objects in the model, we deform the rays used to render the scene. The mechanism to specify the deformation, which we call a deflector, is a vector of gravity positioned in space. This gravity vector bends any ray that travels through its field of grav...

Caricature is an art form that expresses subjects in abstract, simple and exaggerated view. While many caricatures are 2D images, this paper presents an algorithm for creating expressive 3D caricatures from 2D caricature images with a minimum of user interaction. The key idea of our approach is to introduce an intrinsic deformation representation that has a capacity of extrapolation enabling us...

We present a novel approach to real-time shape editing that produces physically plausible deformations using an efficient and easy-to-implement volumetric approach. Our algorithm alternates between a linear tetrahedral Laplacian deformation step and a differential update in which rotational transformations are approximated. By means of this iterative process we can achieve non-linear deformatio...

We present a methodology to derive the growth history of a fault-tip fold above a basal detachment. Our approach is based on modeling of the stratigraphic and geomorphic records of deformation, as well as the finite structure of the fold constrained from seismic profiles. We parametrize the spatial deformation pattern using a simple formulation of the displacement field derived from sandbox exp...

Cartoon animation, image warping, and several other tasks in two-dimensional computer graphics reduce to the formulation of a reasonable model for planar deformation. A deformation is a map from a given shape to a new one, and its quality is determined by the type of distortion it introduces. In many applications, a desirable map is as isometric as possible. Finding such deformations, however, ...

Image-guided prostate interventions often require the registration of preoperative magnetic resonance (MR) images to real-time transrectal ultrasound (TRUS) images to provide high-quality guidance. One of the main challenges for registering MR images to TRUS images is how to estimate the TRUS-probe-induced prostate deformation that occurs during TRUS imaging. The combined statistical and biomec...
