Description
In section 6.2, "Using a Uniform PDF Instead of a Perfect Match", there's a need for clarification to avoid confusion.
The section currently states -
This will still converge on the correct answer, as all we've done is change the PDF, but since the PDF is now less of a perfect match for the real distribution, it will take longer to converge. Which, for the same number of samples means a noisier image:
....
You should get a very similar result to before, only with slightly more noise, it may be hard to see.
In my implementation, I am getting a much brighter image after changing the PDF to uniform, which as per my knowledge is the expected behavior. While the section does mention increased noise, it doesn't adequately address the potential issue of a brighter or dimmer rendered image. This omission can be frustrating for beginners, who would expect to see a slightly noisy image but would instead get a drastically different render after changing the pdf.
Or am I mistaken and going wrong somewhere?
