Before I address temporal supersampling, just a quick reminder on what aliasing is.
在我讲述时间超级采样之前，对锯齿是什么做一个快速的提示。
Aliasing is a problem that is very well defined in signal theory. According to the general sampling theorem we need to have our signal spectrum containing only frequencies lower than Nyquist frequency. If we don’t (and when rasterizing triangles we always will as triangle edge is infinite frequency spectrum, step-like response) we will have some frequencies appearing in the final signal (reconstructed from samples) that were not in the original signal. Visual aliasing can have different appearance, it can appear as regular patterns (so-called moire), noise or flickering.
锯齿是一个在信号理论中意义明确的问题。根据普遍的采样
