title: Using Mesh Shaders for isosurface extraction

authors: Elliott, Hamish Robert

subjects: CGI

abstract: This thesis investigates the use of the Mesh Shader graphics pipeline, utilising in particular its ability of parallel and dynamic choice of geometry, to gain computation efficiencies in realising the Marching Cubes isosurface extraction algorithm. The thesis details how the Marching Cubes algorithm was mapped to the Mesh Shader pipeline, to form a baseline implementation. In addition, two heuristic-based variants are presented that reduced the GPUs workload, but at the potential cost of compromising accuracy. In evaluation of the work, a comparison of the baseline Mesh Shader pipeline implementation is made with a previous compute-shader based implementation. We also present a set of experiments that investigate the speed and accuracy of the two heuristic-based variants.

title: Proceedings of the INTERACT97 Combined Workshop on CSCW in HCI-Worldwide

authors: Rauterberg, Matthias

subjects: computer science

abstract: This is the proceedings for the INTERACT97 combined workshop on “CSCW in HCI-worldwide”. The position papers in this proceedings are those selected from topics relating to HCI community development worldwide and to CSCW issues. Originally these were to be two separate INTERACT workshops, but were combined to ensure sufficient participation for a combined workshop to run. 
The combined workshop has been split into two separate sessions to run in the morning of July 15th, Sydney, Australia. One to discuss the issues relating to the position papers focusing on general CSCW systems, the other to the development of HCI communities in a worldwide context. The CSCW session uses as a case study a proposed groupware tool for facilitating the development of an HCI database with a worldwide geographical distribution. The HCI community session focuses on developing the content for such a database, in order for it to foster the continued development of HCI communities. The afternoon session of the combined workshop involves a joint discussion of the case study groupware tool, in terms of its content and likely groupware facilities.
The position papers have been grouped into those focusing on HCI communities and hence content issues for a groupware database, and those focusing on CSCW and groupware issues, and hence likely groupware support in the proposed HCI database/collaboration tools. We hope that you find the position papers in this proceedings offer a wide range of interesting reports of HCI community development worldwide, leading CSCW system research, and that a groupware tool supporting aspects of a worldwide HCI database can draw upon the varied work reported.

title: Experiencing cultural tourism: Visitors at the Maori Arts and Crafts Institute, New Zealand

authors: Ryan, Chris

subjects: indigenous tourism

abstract: This study reports results derived from semistructured interviews with 40 visitors to the Maori Arts and Crafts Institute in Rotorua, New Zealand. The article discusses briefly the mode of data capture used and adopts an approach of identifying classifications of a primarily functional nature to list reasons why people visit such a site and what it is they seek. In general, visitors reported high levels of satisfaction, yet the cultural component of their experience was primarily reported in terms of the visit being informative and entertaining. Additionally, whereas modest levels of interest in things Maori seemed to motivate visits to other Maori sites, the actual list of other locations being nominated was few in number. The impression results that visits are made to Maori sites because this is a "done thing" when visiting New Zealand, but overall, the level of interest shown by most visitors in indigenous culture is modest.
