Estimation of Error in Curvature Computation on Multi-Scale Free-Form Surfaces
A novel technique for multi-scale curvature computation on a free-form 3-D surface is presented. This is achieved by convolving local parametrisations of the surface with 2-D Gauss...

Modeling plant structures using concept sketches
Creating 3D plant models is often a hard and laborious task. To make it easier and more natural, we propose a sketch-based interface for modeling single-compound plant structures ...

Epipolar sampling for shadows and crepuscular rays in participating media with single scattering
Scattering in participating media, such as fog or haze, generates volumetric lighting effects known as crepuscular or god rays. Rendering such effects greatly enhances the realism...
