Visualization of Objects in the Vicinity of Black Holes

Rachel Mary Costello

Three computer simulations written in C++ have been created to model the visual appearance of a star, a star field, and an accretion disk in the vicinity of a Schwarzschild black hole in three-dimensional space. The models allow for flexibility in the placement of the objects and the observer in relation to the black hole. The programs attempt to illustrate basic gravitational lensing effects to give insight into the theory.
