This project revolves around the use of imposters as replacement of real particle or fluid system in interactive environments. This is done to maximize frame rates. During the test a set of complex imposters which changes viewing angle of the actual animation will be compared to a normal imposter that is constantly viewed from the same angle. This will be to test whether or not the difference in orientation is a major factor in the perceived quality of the effect. However as no test has been conducted yet, the results cannot be presented. This report is still a work in progress and is thus incomplete.
