The Personal Interaction Panel - a Two-Handed Interface for Augmented Reality
(Blackwell Publishers Ltd and the Eurographics Association, 1997)
This paper describes the introduction of a new interaction paradigm to augmented reality applications. The everyday tool handling experience of working with pen and notebooks is extended to create a three dimensional ...
Consistent Schemes for Addressing Surfaces when Ray Tracing Transparent CSG Objects
(Blackwell Science Ltd and the Eurographics Association, 1992)
Constructive Solid Geometry (CSG) defines the shape of objects, i.e. the inside and the outside regions of objects, but it does not define the material properties of the space in the interior of objects. The definition is ...
Two-step Prediction and Image Deflection for Exact Head Tracking in Virtual Environments
(Blackwell Science Ltd and the Eurographics Association, 1995)
An Image based Measurement System for Anisotropic Reflection
(Blackwell Science Ltd and the Eurographics Association, 1996)
This paper introduces an image based method for measuring bidirectional reflectance distribution functions (BRDF). The measurement system uses a CCD camera connected to a workstation to capture images from the material ...
Demand-Driven Geometry Transmission for Distributed Virtual Environments
(Blackwell Science Ltd and the Eurographics Association, 1996)
We present a strategy for rendering in distributed virtual environments. A geometry database is maintained by a server, while users invoke individual clients to interact with the environment. Instead of downloading a ...
CCD-Camera Based Optical Beacon Tracking for Virtual and Augmented Reality
(Blackwell Science Ltd and the Eurographics Association, 1996)
We introduce a scheme for optical beacon tracking using two CCD-cameras and LED beacons. Due to the sub-pixel accuracy of the beacon detection algorithm a very high precision can be achieved so that the tracking method is ...
