This project builds on an existing Covid-19 simulation from Kutztown University, which tracks the spread of the virus across the campus via infected students and faculty traveling from class to class. The expansion adds polar geometry to visualization of the simulation for circular display in a planetarium or some other immersive environment. In the original code, each class was plotted using (X,Y) values in physical space based on the rectangular display. Polar geometry was achieved by plotting each class using (angle,radius) values instead, which allowed for rotations and resulted in a circular layout. In addition to the polar geometry, the expansion also builds all graphical primitives into one big vector shape and plots them all at once (instead of separately and one-by-one) in order to accelerate the simulation. This change, however, caused a trade of time for memory, since the elapsed time decreased by 34% while the memory consumption increased by 3400%.
