5RJ commented 4 years ago

Thank you for what you have done! I'm confused about the translate matrix .here are the specific question: (1)Is the original focal length=1(i.e. if elevation=0deg) ? (2)Why the translate matrix set to be as follows at first? 1

could you please explain it? I'll appreciate for you reply!
