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.
Stochastic = Random. Stochastic AA, Anti-aliasing technique based on randomized sample distribution (as opposed to fixed sample pattern).
Also see: Monte Carlo Method
Temporal = depends on time. Temporal coherence, how consistent X is over time.
Typically you hear of temporal aliasing, temporal artefacts etc.
