# Chapter 3: The Rendering Pipeline As I read this book, I summarize what I think is wrong. If you think my comments are wrong then please let me know. We can dicuss more and update your opinion. ## The rendering pipeline * There is a typo on page 86. It should be replaced to alpha testing. So the correct sentence will be like that **alpha-testing** determines which opaque objects are drawn and which are not based on alpha testing.
