I might missed it in the class. What is the standard FPS to define "Real-time"?
@cche Good question. I think it depends who you ask. Films/movies are usually recorded at 24 frames per second, though there are some exceptions (e.g., the Hobbit); Btw, not everyone is a fan of higher frame-rates in film. Video games traditionally target 60 frames per second, because this was the standard refresh rate of most computer monitors. There are computer monitors that support faster refresh rates up to 240 Hz, though there are diminishing returns in terms of a human's ability to see the difference.
In short, there is no standard definition for "real time", and it depends on the context. But I think there is a reasonable argument that it should be 25 FPS.
