Can i retrieve position,orientaion,direction.Sorry,execute my poor math!
I assume you’re talking about the camera position and direction (which is somewhat synonymous with orientation, since the direction is the result of orienting the camera in the world). Further assuming that the camera has an initial direction of (0, 0, -1), multiplying this direction with the inverted upper 3x3 matrix of the view matrix yields it’s world space direction. Translation with the negated 4th row of the matrix (except for the w-component) yields its position. You can get different results depending on the order of operations, i.e. first translating and then rotating generally isn’t the same as doing it in reverse.

Nope, that would be illegal in most countries.
