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 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.
