Modeling of Trees with 3D Gestures and Growth Simulation
(The Eurographics Association, 2005)
We propose a modeling system that enables users to create tree models with 3D gesture input. It generates tree models by using growth simulation based on the trunk or silhouette shapes of trees given by user gestures. The ...
Friction surfaces: scaled ray-casting manipulation for interacting with 2D GUIs
(The Eurographics Association, 2006)
The accommodation of conventional 2D GUIs with Virtual Environments (VEs) can greatly enhance the possibilities of many VE applications. In this paper we present a variation of the well-known ray-casting technique for fast ...
Multi-scale Manipulation in Indoor Scenes with theWorld in Miniature Metaphor
(The Eurographics Association, 2009)
The World in Miniature Metaphor (WIM) allows users to select, manipulate and navigate efficiently in virtual environments. In addition to the first-person perspective offered by typical VR applications, the WIM offers a ...
