A spatially-aware tangible interface for computer-aided design
This paper presents a Computer-Aided Design (CAD) platform for designers to navigate and construct 3D model intuitively through Tangible User Interfaces (TUIs). We suggest that 3D...

Parallel Banding Algorithm to compute exact distance transform with the GPU
We propose a Parallel Banding Algorithm (PBA) on the GPU to compute the exact Euclidean Distance Transform (EDT) for a binary image in 2D and higher dimensions. Partitioning the i...

A novel page-based data structure for interactive walkthroughs
Given a data layout of a large walkthrough scene, we present a novel and simple spatial hierarchy on the disk-pages of the layout that has notable advantages over a conventional s...

Hair self shadowing and transparency depth ordering using occupancy maps
This paper presents a method for quickly constructing a highquality approximate visibility function for high frequency semitransparent geometry such as hair. We can then reconstru...
