I am assuming that the camera's transform matrix transforms any point's absolute [X,Y,Z,1] model/point cloud coordinates into a new space relative to the camera's local coordinate system. If I take the inverse of this matrix and then multiply it by the origin for the camera's local space augmented with a 1 to make a 4-dimension vector [0,0,0,1] then I should get the augmented camera's coordinates [X,Y,Z,1]. Can someone verify if this is correct?
Or is the camera's transform matrix already the inverse of the matrix that transforms camera relative to absolute coordinates in such case that I don't need to take the inverse of the matrix?
