"Contrast sensitivity can be described as the minimal frequency and contrast required such that two distinct stimuli are perceived as separate."
- Implementing four methods which exploit quality degradation of resolution, Screen-Space Ambient Occlusion (SSAO), tessellation, and ray-casting steps with visual eccentricity.
- Discerning at what level of degradation do artefacts become noticeable to the observer.
- A function for calculating the foveal window size.
- Experimentally confirming why resolution degradation is a popular (and successful) method for foveation.
