What is the meaning of words 'stochastic', 'temporal' in computer graphics? Last time I see a lot of papers which operates on this words, i.e. stochastic AA, temporal coherence etc. What does that means? Can you provide examples with explanations in plain English?
A stochastic process is one where you gather your samples randomly. So stochastic AA is antialiasing where you gather multiple samples for the same pixel with small random changes.
Temporal refers to a process over time. Temporal coherence is for instance mentioned when you have no flickering artifacts, or aliasing that you see during movement. It means that frames are coherent in a certain time window.
