I think the code review method is good. I saw another comment in the discussion about how the Cameraraycaster codes can be a bit complex and require a bit of assumed knowledge. I guess to counter that problem, maybe you can set code reading/research challenges. So during the class, you can explain relevant parts and have people research the sections that we will need later, learn to read it and do challenges.
That said, I still think following along to code a bit is good to have. I suppose we need to find a balance between that and time factor as well.
All in all, I’m happy with the way things are going.
