Question about ConstructTrans function #113

Open ShuyiZhou495 opened 1 year ago

ShuyiZhou495 commented 1 year ago

Hello, author. The idea of perspective warping is just too smart and I want to try on my workframe. But I am not familiar with C++ and I have some questions about the ConstructTrans function.

Maybe I misunderstand, but I think you rotate the cameras so that the z axes of the cameras are towards the center point in the ConstrucTrans function. Won't it change the situation from perspective to some kind of 360 degree scenario? If I want to use the warping function, is it necessary for me to turn the cameras around?

I will really appreciate if you reply me!
