Question about the coordinate system

UestcJay opened this issue · comments

hi, many thanks for your great work! I have questions about the line code. In nerf, there is opengl -> opencv, so y and z mul -1. Is it right? But why you also mul -1. I don't know when to multiply -1
Thanks for your time!
