In this paper, we present a feature-based free-form shape modelling technique based on solving a fundamental problem of reconstructing the depth information from 2D sketch planes....
This paper describes on-going work in the analysis of motion dynamics in pen-based interaction. The overall goal is the creation of a model of user motion in pen gestures where co...
We propose an efficient framework for dynamic cloud rendering. Base on the proposed simplified lighting model, the Shadow Relation Table (SRT) and Metaball Lighting Texture Databa...
Arc splines are G1 continuous curves made of circular arcs and straight-line segments. They have the advantages that the curvature of an arc spline is known and controlled at all ...
Three-dimensional fractals consisting of constellations of spheres can be constructed by iterative sphere inversions. Three methods are explored in this brief artistic statement. ...
Many applications of geometry processing and computer vision rely on geometric properties of curves, particularly their curvature. Several methods have already been proposed to est...
We describe a trainable, hand-drawn symbol recognizer based on a multi-layer recognition scheme. Symbols are internally represented as binary templates. An ensemble of four differ...
Sketch-based user interfaces provide a more direct and convenient way for interacting with computers, especially for performing graphical tasks. Most computer programs provide a m...
Early in the development of Computer Graphics it was realized that projective geometry was well suited for the representation of transformations. Now, it seems that another change...
Sketch recognition systems are currently being developed for many domains, but can be time consuming to build if they are to handle the intricacies of each domain. In order to aid...
