On Camera
Published:
Have you ever wondered how cameras project an object in 3D space into a 2D image? This post covers the overarching process and dives deep into the first half of it. I am writing this post because, despite being a fundamental concept, there are surprisingly few guides that explain it clearly—mostly due to an overload of redundant terminology with identical meanings, and because most tutorials jump straight into equations without establishing basic intuition. I personally struggled with this during my own research, so I hope this post helps anyone tackling the subject in the future.
