Viewpoints: A high-performance high-dimensional exploratory data analysis tool

Scientific data sets continue to increase in both size and complexity. In the past, dedicated graphics systems at supercomputing centers were required to visualize large data sets, but as the price of commodity graphics hardware has dropped and its capability has increased, it is now possible, in principle, to view large complex data sets on a single workstation. To do this in practice, an investigator will need software that is written to take advantage of the relevant graphics hardware. The Viewpoints visualization package described herein is an example of such software. Viewpoints is an interactive tool for exploratory visual analysis of large, high-dimensional (multivariate) data. It leverages the capabilities of modern graphics boards (GPUs) to run on a single workstation or laptop. Viewpoints is minimalist: it attempts to do a small set of useful things very well (or at least very quickly) in comparison with similar packages today. Its basic feature set includes linked scatter plots with brushing, dynamic histograms, normalization and outlier detection/removal. Viewpoints was originally designed for astrophysicists, but it has since been used in a variety of fields that range from astronomy, quantum chemistry, fluid dynamics, machine learning, bioinformatics, and finance to information technology server log mining. In this article, we describe the Viewpoints package and show examples of its usage.Comment: 18 pages, 3 figures, PASP in press, this version corresponds more closely to that to be publishe

Gamedec. UKW in IGDA Curriculum Framework

Launched in October 2013, GAMEDEC: game studies Design is a specialisation track within the 2nd Gen Humanities (aka Humanities 2.0) 3-year BA programme at Kazimierz Wielki University (UKW) in Bydgoszcz, Poland. The curriculum was created by UKW academic staff with game design experience, guided by the IGDA 2008 Framework and consulted with game dev professionals. It underwent slight modifications in 2014 and a significant transformation in 2015. This paper aims at a thorough analysis of the structure of the curriculum as seen through the lens of the IGDA Framework (2008), including the coverage of both Core Topics and Institutional Considerations. The analysis is conducted in the context of foreign (mostly U.S.- based) game degrees and supported with comments on its design, implementation and modifications
