unfold

In this project, unfold, artist Ryoichi Kurokawa used 2 type of astrophisics data, observation data and numerical simulation data. Observation data includes various electric magnetic wave mainly from Vela such as H-Alpha wave from molecular cloud in Vela C region, X-ray from Pulser Vela, far infrared wave of dust emission in the Vela Molecular Ridge. The data was captured by 4 Space telescope, Herschel Space Observatory, Planck Space Observatory, Spitzer Space Telescope and Chandra X-ray Observatory. Data was provided as image or FITS file. Numarical simulation data includes simulation of shockwave effect to molecular cloud, gallaxy collision and super nova explosion. These simulation was implemented as a libray of Fortan code(Heracles, Dumses, COAST) which solve fixed grid astrophysical fluid flows. It was excuted on CEA supercomputer cluster. Simulation result was dumped as a set of HDF5 file or Fortran Unformatted Binary which contains sevelal parameters( particle density, velocity, energy, radial velocity, ...) in 64 bit floating point accuracy. These data was converted to appropriate data set and filtering and mininging process was applyed. Sound, visual and vibration data material was generated from custom application. Original data was employed as parameters of color, speed, velocity, shape, raw sound/vibration data, frequency control or initial/control variables for another algorithm. Artist aimed to realize different output from common scientific visualization/sonorization. Various astrophysics origin/non-origin software was used in production process including Karma, FITS Liberator, SAOImage DS9, Cinder, Qgis, and Blender. Electromagnetic waves is not visible with human eyes in a wide range of wavelengths. Therefor there is no 'correct' color to represent the data. Scinetifician use 'psudo' color or sound for understanding of data and research presentation. unfold is realized as visual/sound/vibration stimulus from different angle, which lead us to find the beauty of data/phenomena itself.
