Bunkspeed Shot processed image of Spectramap Rhino Virus (OBJ file)

We have used Bunkspeed Shot to create a photo realistic image of a Spectramap Biplot from Rhinovirus test data. A Spectramap Biplot visualizes the contrast between row items (common-cold virus strains) and column items (antiviral compounds) of a data table. The data was published in: J Virol 1990 64 3 1117–1123 K Andries, B Dewindt, J Snoeks, L Wouters, H Moereels, P J Lewi, ‘Two groups of rhinoviruses revealed by a panel of antiviral compounds present sequence divergence and differential pathogenicity.’ The Spectramap Biplot can be thought of as a multidimensional scatter plot. Instead of three axes (XYZ) to scale three variables (e.g. in this example only three antiviral compounds), the biplot uses decomposed factors of both the columns and the rows of the original data table. Therefore, we are able to see all items in one plot, one 3D system of informational objects: cubes for columns and globes for rows. Note that they differ in size, which shows the mean potential of the antiviral compound or the mean sensitivity of the common-cold virus. Furthermore, color coding was applied to indicate the spectral contribution of the next three higher decomposed dimensions (i.e. factors 4, 5 and 6). Some of the items have their label displayed but all items have one. The Bunkspeed Shot photo realistic image adds a visually appealing additional sense of depth to the visualization. We hope soon to be able to have one published on the cover of a scientific journal!
