Hi

I am interested in Image Modeler, but I need to know how the distorsion is modeled in it, the information on this point is nowhere to be found! the distorsion aspects of the problem also seem excluded from the tutorials while it can be very problematic when modeling objects from pictures!

I know earlier versions (from REALVIZ back then) used to model it as radial distorsion with only one parameter, but this isn’t enough :)
I need to know precisely the model since I will use the measures in my own software, not in a 3D modeler such as 3DS max, which -to my knowledge- doesn’t come with a distorsion adder/correcter!

So correct me if I’m wrong, but there is no way to re-add distorsion to a render made in 3DS Max into the original pictures I would have worked on in Image Modeler! I could pay for a plug-in but I wouldn’t know how to use the values computed by Image Modeler!
(this isn’t what I call full integration with 3DS max, so I do hope I’m wrong with this :) )

I would have to work on undistorted pictures, so then I would use my own methods to estimate and correct the distorsion, and I could completely master how it’s corrected, and how it’s added back… but there are many other advantages to Image Modeler that I am interested in!

Please bring me up to speed on this issue!

Note: the model is use is described in this paper, and I limit myself to the 2nd degree:
