It would definitely be more convenient for me if you had a -matrix option. I'm
not sure off the top of my head how to go from my camera matrix to your
latitude/longitude/roll (although I'm sure I could probably figure it out).

I'll take a look. There's not currently any way to get the position portion of
the camera matrix out of LDView, but I can hack something together for a test.
I suspect the rows/columns might have to be swapped, but I don't see how
POVRay's matrix could be anything but a standard 3D transformation matrix.

| Thanks to both of you. Just for me, I would be completely satisfied if LDView shows (and exports to clipboard) full 4*4 trafo matrix instead of 3*3 matrix as it does in current version. Then I am able to derive .pov trafo matrix by myself. Small (...) (19 years ago, 4-Dec-05, to lugnet.cad.ray, FTX)
