The second topic, the creation of complex animation data, speaks to the relationship between frame rate and current animation practices. Typically character animation data is created not on a frame-by-frame basis, but by setting important positional information at specific key frames and then interpolating between the keys using spline-based curves. This presents a special problem with respect to HFR animation in that these curves do not increase in complexity as they are
subsampled. When compared to CGI, photography excels at capturing the complexity of reality, and so this is an area which must be addressed in the synthetic world in order to create effective tests of the perception of detail and clarity.
