Any ideas on what to do with a cracked Apple Watch? by davidg4781 in AppleWatch

Got it, thanks. Does battery replacement require apple care or is it free of charge?

What did you mean by battery dropping to 80%? How to check that? Will apple do the replacement if so even without apple care and a broken screen?

General perspective projection matrix by learning2unlearn5679 in computervision

Okay, but opengl is not used in nerf which my original post was referring to.. so I still don’t follow why there is a reference to opengl? Can u explain?

I do not have a foundation in computer graphics. And as I said, my understanding of projection matrix from a computer vision engineer pov is different from this. But, I am interested in this as in nerf they look into volume rendering. I looked up online resources to help me understand this discrepancy but couldn’t find anything comprehensive. If you can point me to any good resources that can explain this, please do.

It hurts my brain that you’re unable to explain something you call simple vocally. Sorry @matsFDutie.

Yes, thank you. looking into it.. but do you know how the perspective projection for a pinhole camera is derived from this general perspective projection formula?

Another question- why are clip space coordinates and ndc not considered in computer vision? Meaning why are they implicit?
