Visualizing and exploring planar algebraic arrangements: a web application
A web application is presented to compute, plot, and interactively explore planar arrangements induced by algebraic plane curves of arbitrary degree. It produces accurate curve pl...

Cata-Fisheye Camera for Panoramic Imaging
We present a novel panoramic imaging system which uses a curved mirror as a simple optical attachment to a fisheye lens. When compared to existing panoramic cameras, our “cata-...

Curved surfaces and coherence for non-penetrating rigid body simulation
A formulation for the contact forces between curved surfaces in resting (non-colliding) contact is presented. In contrast to previous formulations, constraints on the allowable ta...

Art-based Rendering of Fur, Grass, and Trees
Artists and illustrators can evoke the complexity of fur or vegetation with relatively few well-placed strokes. We present an algorithm that uses strokes to render 3D computer gra...
