Figure 1: A backyard scene rendered with a 2k × 2k shadow map and 5 × 5 Gauss filtering using (from left to right, statistics include mip-map memory): CSMs ESMs require 8× less memory than CSMs and have less light leaking at contact points while their filtering quality is almost indistinguishable. Like CSMs, ESMs also avoid the high frequency light leaking(More)
Designers and developers of virtual environments have to consider that providing adaptation in virtual environments is important to comply with users' different characteristics. Due to the many possibilities of adaptation that a designer can think of, it is necessary to support the integration of adaptation in the application in a rapid and practical way.(More)
This paper presents FluidPaint, a novel digital paint system using real wet brushes. A new interactive canvas, accurately registering brush footprints and paint strokes in high precision has been developed. It is based on the real-time imaging of brushes and other painting instruments as well as the real-time co-located rendering of the painting results.(More)
omputer-supported collaborative work over networks has become an important research topic over the past few years, including in the Visinet project. The Visinet participants conducted trials of new CSCW methods based on virtual representation and virtual reality techniques over trans-European ATM networks. Designers, architects, city planners, and engineers(More)
The use of handheld computers as a tool to enrich the museum experience has found its way into many museums, opening up new possibilities to increase the attractiveness of museum visits, especially for youngsters. We developed a mobile guide framework that supports the creation of mobile guides and adheres to social-constructivist principles of learning.(More)
