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 (also available in DAZ and HiveWire3D flavours) 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.
