title: Distributed OpenGL Rendering in Network Bandwidth Constrained Environments

authors: Neal, Braden

subjects: computer science

abstract: Display walls made from multiple monitors are often used when very high resolution images are required. To utilise a display wall, rendering information must be sent to each computer that the monitors are connect to. The network is often the performance bottleneck for demanding applications, like high performance 3D animations. This paper introduces ClusterGL; a distribution library for OpenGL applications. ClusterGL reduces network traffic by using compression, frame differencing and multi-cast. Existing applications can use ClusterGL without recompilation. Benchmarks show that, for most applications, ClusterGL outperforms other systems that support unmodified OpenGL applications including Chromium and BroadcastGL. The difference is larger for more complex scene geometries and when there are more display machines. For example, when rendering OpenArena, ClusterGL outperforms Chromium by over 300% on the Symphony display wall at The University of Waikato, New Zealand. This display has 20 monitors supported by five computers connected by gigabit Ethernet, with a full resolution of over 35 megapixels. ClusterGL is freely available via Google Code.

title: The importance of restoring the Rotorua Lakes

authors: Chadwick, Hon Steve

abstract: In November last year the Rotorua District Council resolved to change our trading name to Rotorua Lakes Council. This was passed at Council and caused a stir; everything I do seems to cause a stir because we did not consult the wider community. In retrospect I still believe it was the best decision to keep at the Council table.

title: A report to iwi on the kaupapa Māori environmental outcomes and indicators kete

authors: Jefferies, Richard

subjects: New Zealand

abstract: Tangata whenua in Aotearoa have been largely excluded from participation in local government  planning since colonisation, but tikanga and Māori values have for the past two decades been acknowledged in resource management and local government legislation, especially the Resource Management Act, 1991 (RMA) and Local Government Act, 2002 (LGA). For example, the RMA has provisions in over 30 sections for councils to give effect to Māori interests.

In practice, however, there is widespread concern that despite these provisions, Māori are largely excluded from local government resource management processes and their values subordinated to those of the wider community, particularly western scientific values.

This report describes research that resulted in a kaupapa Māori outcomes and indicators framework, and associated methods, that can be used by iwi to assess the quality of statutory plans and the environmental performance of councils in their rohe.
