I have been working on my own renderer for a while, and I'm wondering if there's any way to remove the Monte Carlo noise from the rendered image, besides waiting for a long time for it to converge?The way I found is to blur the image, which is not really helpful, since it reduces the quality/sharpness of the image a lot. And I can achieve the same thing by rendering a small image with more samples, then scaling it up.Is there any algorithm designed to deal with noise in the image in path tracing?
