The daVinci Pursuit and Scientist Ruben Sandoval are working with experts from the Indiana University School of Medicine (pathologists, cellular biologists, medical imaging professionals) and faculty from the Indiana School of Informatics (music informatics, artificial intelligence, visualization and animation, advanced computing) to design new ways to explore 3D images from the field of medicine throughout the campus of the Indiana University School of Medicine.
Artistic Statement (Ruben Sandoval):
My contribution to the research we conduct in our laboratory focuses on in vivo imaging. Here, I attempt to corroborate observations made by other technologies, within a living system which is capable of providing spatial (where are these change in physiology occurring?) and temporal information (and when?). The three dimensional data sets I collect in particular have the ability to convey stunning realizations in the differences that occur between normal and altered physiologic states.
This art project started out with my desire to introduce the perception of depth into the tessellations I make from these images. There are two methods I use to convey the three dimensional information.
The first is the most simple; the creation of red/cyan anaglyphs that are viewed using red/cyan filtered glasses. This method is the easiest for most viewers to become accustom to with the only drawback is the loss of the color palettes that occur naturally in these images.
The second method preserves the inherent color information but it is more difficult to visualize; relying on “deep” or “relaxed” focus to merge repetitive visual landmarks and induce stereoscopic vision. This technique was popularized in the early 90’s in books and prints under the generic “Magic Eye” moniker. In the work presented here however, the viewer is able to distinguish more than simple or intricate shapes that “float” above the perceived background. Because the research images I collect have inherent special information, by rendering two different viewing angles and processing the resulting images identically then overlaying one small section over the other, the upper and lower viewing planes will reveal spatial information about the living structures while the middle plane will appear “flat”. This accidental observation has motivated me to continue delving into making subtle adjustments that can aid the viewer in perceiving the spatial information contained within these static images.
