Description

The web-based virtual environment you built is fantastic! I'm interested in the reconstruction.html file. Especially the opticalCenter (shots) function and rotate function inside, I don't quite understand how they use the rotation and translation of the camera. Could you tell me the mathematical and practical significance of the rotate function and the opticalCenter function? What is the difference between the camera pose and the opticalCenter which you get? Thanks for your reply!

Research direction

Start by reading reconstruction.html, focusing on the opticalCenter(shots) and rotate functions and their surrounding camera-pose code. Compare the available comments or related OpenSfM reconstruction documentation, then document the mathematical and practical roles of both functions and the distinction between camera pose and opticalCenter.
