Interactive visual music

How can Visual Music be composed and presented in such an engaging way that it will turn spectators into participants? How to connect a youthful, twenty-first century audience who are keen to update their Instagram story with Visual Music? Visual Music is an art form, which is “an equal and meaningful synthesis of the visible and audible” (Lund & Lund 2009 149) and “is typically non-narrative and non-representational” (Evans 2005 11). Visual Music is often presented as cinema. Cinema audiences are generally considered to be passive spectators, whose “reactions are pre-programmed by the director, crew, cast and writer” (Mackintosh 2003 2). This paper highlights the nexus between, to use McCall’s (2004) terms ‘the cinematic, the sculptural and the pictorial’, with a focus on creating interactive Visual Music installations

Structural analysis of the central Columbia Plateau utilizing radar, digital topography, and magnetic data bases

Interest in the Hanford site (Washington) as a nuclear production, power, and waste disposal site has led to generation of a vast quantity of geophysical and remote sensing data sets of the central Columbia Plateau. To data, these various studies, including at least 13 independent magnetic linear and image lineament studies, have not been adequately correlated. Therefore, these studies provide a unique opportunity to compare and contrast the viability of the different geophysical and remote sensing techniques. The geology of the central Columbia Plateau is characterized by subdued topography and limited outcrop, with most of the exposure concentrated in localized folded/faulted mountains (the Yakima folds) and along river canyons. In order to efficiently compare lineament data bases, we have written an automated computer routine that correlated lineaments that are within a user specified distance of each other. The angle between their trends has to be less than an input maximum separation angle. If more than two lineament maps exist for the area, the analyst may also specify the minimum number of times each structure must be seen. The lineament correlation routine was applied to data bases of all aeromagnetic linears as well as lineaments seen on radar and a digital elevation model DEM image. Geologic structures align with a set of three-dimensional planar structures identified with our Geologic Spatial Analysis (GSA) system. The GSA analysis is based upon computer automated detection of valley bottoms as defined by a DEM
