How can I make sure that 3D plots have the exact same orientation and viewpoint?

First off, I apologize that I can't come up with a simpler working example, but I only seem to have this problem with the larger examples.

I am trying to make animations, using functions like the ones listed here. In order to make an animation, I need for the resulting 3D image to have a stationary camera. Here are two examples that I can't get this to work on. My apologies on the filesize, both of the images are 14MB when put into a text file.

img1 = Import["https://dl.dropboxusercontent.com/s/8878c5m3cjv2zmv/img1.m"];
img2 = Import["https://dl.dropboxusercontent.com/s/qbyx4t7yexoerqc/img2.m"];
GraphicsRow[{img1, img2}]


If it isn't obvious that the two images have a different orientation, then try this:

    Manipulate[Show[{img1, img2}[[n]], ImageSize -> 500], {n, {1, 2}}]


I have even tried to make sure that they have the same options for ViewPoint, ViewVertical, and ViewCenter. This can be verified by a function I made,

Quiet[viewpoint[graphics_] :=
Evaluate[
FilterRules[{AbsoluteOptions[graphics]}, {ViewPoint,
ViewVertical, ViewCenter}]];];
viewpoint /@ {img1, img2}


which returns

(*{{ViewCenter -> {0.5, 0.5, 0.5}, ViewPoint -> {0.141, 0.19199, -3.37},
ViewVertical -> {0.0417, 0.0978, -2.0278}}, {ViewCenter -> {0.5,
0.5, 0.5}, ViewPoint -> {0.141, 0.19199, -3.37},
ViewVertical -> {0.0417, 0.0978, -2.0278}}}*)


So what am I missing? How can I make sure that every single time I create a 3D image that the view is identical? Is there another important viewing option besides those 3?

There are more View* options: ViewVector, ViewAngle, ViewVertical, ViewPoint, ViewCenter, and ViewRange (I think the first three are the ones you need to fix). Instead of setting each of these individually, you can just set the ViewMatrix (which in turn depends on these) and you should be fine. See this question for more, especially Heike's answer: mathematica.stackexchange.com/q/3528/5 (I think this fully addresses what you want to achieve) –  rm -rf May 16 at 22:44
@rm-rf, I am not finding the page you linked to to be especially helpful. In particular, I don't see that anyone answered the OP's question. What I apparently want is a function that can operate on a graphics object and return the ViewMatrix. –  Jason B May 16 at 23:01
