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 ...
