Nettet30. +100. Assuming your matrix is an extrinsic parameter matrix of the kind described in the Wikipedia article, it is a mapping from world coordinates to camera coordinates. So, to find the position C of the camera, we solve. 0 = R C + T C = − R T T ≈ ( − 2.604, 2.072, − 0.427). The orientation of the camera is given simply by R T.

"NettetHow camera controls work. The camera position and direction is determined by three vectors: up, center, eye. Their coordinates refer to the 3-d domain, i.e., (0, 0, 0) is always the center of the domain, no matter data values. The eye vector determines the position of the camera. The default is $ (x=1.25, y=1.25, z=1.25)$. " - Movement vector from camera perspective

NettetThis is done by a translation using the negative vector of the camera position. So if the camera is positioned at (1,2,3) we need to move the object by (-1,-2,-3) in order to get the camera back to the origin. After that we generate the camera rotation matrix based on the camera target and up vectors.
