Back to aRtBee's "...can somerun run similar tests for the Revolving cam?"
I've just completed a very simple initial test to get approximate figures.
I imported a large cube OBJ that I created into Poser 9 - centred at the origin, each face is a different colour, and all faces face inwards.
I set up a single point light at the origin so I'll actually see something when the camera's inside the cube.
I set the Main Camera DollyX/Y/Z and OrbitX/Y/Z to (0,0,0) , focal length to 12.7mm (as per dolly cam), and scale to 100%.
I set the view to use the main camera, and ensured that the view pane width and height were equal.
I then adjusted the main camera's DollyX until the cube face I was looking at just about filled the FOV. The DollyZ value I got was about -113" / -290cm / -1.1PNU
I then rotated the main camera to point at each of the remaining five cube faces i.e. OrbitX/Y/Z set to (0,90,0), (0,180,0), (0,270,0), (90,0,0) and (-90,0,0). Each face just about filled the fov perfectly. I didn't render
I also got the same results as above for the Aux and Posing Cameras. (I also tried this simple test with the Face/Hand cameras, but ran into other problems, so I can't say anything about those yet)
My initial conclusion is that the main/aux/posing cameras in Poser 9 seem to produce a 90° FOV with the same 12.7mm focal length as the dolly camera, and that the main camera's offset is about 113" along the Z axis (I won't say + or - since it depends how you define the offset!). More tests are still required to verify this and to get more precise figures.
The 3Dcheapskate* occasionally posts sensible stuff. Usually by accident. And it usually uses Poser 11, with units set to inches. Except when it's using Poser 6 or PP2014, or when its units are set to PNU or something else.
