Smoothing an arc spline
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 ...

Sphere inversion fractals
Three-dimensional fractals consisting of constellations of spheres can be constructed by iterative sphere inversions. Three methods are explored in this brief artistic statement. ...

Curvature and torsion estimators based on parametric curve fitting
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...

An image-based, trainable symbol recognizer for hand-drawn sketches
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...

Geometric computing in computer graphics using conformal geometric algebra
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...

LADDER, a sketching language for user interface developers
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...

A novel constrained texture mapping method based on harmonic map
In this paper, we present a novel constrained texture mapping method based on the harmonic map. We first project the surface of a 3D model on a planar domain by an angle-based-fla...

Combining geometry and domain knowledge to interpret hand-drawn diagrams
One main challenge in building interpreters for hand-drawn sketches is the task of parsing a sketch to locate the individual symbols. Many existing pen-based systems avoid this pr...

A hierarchical sampling approach for polygonizing variational implicit surfaces
This article discusses an enhanced polygonization algorithm for variational implicit surfaces. The polygonization scheme is a simple hierarchical adaptation of the Marching Cubes ...
