Sorry, Robert Comsol, I gotta go with blssdwlf on this one.
No need to be sorry. This is not about supporting a rationalization theory (I got one for later today regarding the interpretation of the TWOK torpedo bay footage).

I would just like to remind that the issue that started this discussion was not "how to exactly measure the max. width of the connecting dorsal based on pictures" but "would the dorsal's width in an orthographic drawing be 48% of the torpedo bay launcher's width or rather 59%?"

Let's have again a look at the latest wireframe graphics published.

On the left side we have exclusively stern views of the dorsal while the two on the upper right are bow views. Unfortunately the width of the torpedo bay launcher as a reference point is 67 mm (on my screen) on the left and 6% less on the right side.

All the three on the left are orthographic renderings while the three on the right are simulations of how they'd appear in pictures and the like with the inevitable distortions you get because objects further from the viewer will appear smaller / narrower than objects closer to the viewer (especially with a diagonal connecting dorsal in contrast to the "straight" conning tower of a submarine).

However, since we are looking at a basic "ovoid" dorsal shape the edge of the dorsal's bow is too narrow to "hide" the wider dorsal areas behind.

On my screen this orthographic rendering on the left shows the maximal width of the dorsal to be 37 mm, the "picture view simulation" on the top right takes the distortion into account and therefore yields only 29 mm (- 6% = 27 mm) where the dorsal rests on the torpedo bay because the maximal width of the dorsal is further from the viewer than the launchers of the torpedo bay - it therefore appears narrower than it is in relation to the observable width of the launchers.

Conclusion: The max. width of the connecting dorsal part (that rests on top of the torpedo bay) in pictures appears narrower than it would be in real life compared to the observable real life width of the torpedo launcher (reference point for measuring)



That the dorsal's width in the above picture near the torpedo bay roof measures "only" 56.7% (and not 59%) therefore doesn't come as a big surprise because the widest part of the dorsal is not near the bow and atop the torpedo bay launchers but further behind and at a greater distance from the viewer and/or camera.

Bottom line: Regardless whether the max. dorsal width is 59% (my estimate) the width of the torpedo bay launcher or 56.7% it most definitely is not 48% as the CGI TMP DE model orthographic rendering wants to make us believe.



@ QuinnTV & Maurice

Great pictures gentlemen, thanks! The one Maurice provided will help me immensely trying to reconstruct a decent top view of the torpedo bay.

But here is one from cloudster.com (hopefully back online soon again) that should be helpful, because it's a straight stern view of the TMP Enterprise's connecting dorsal.

Of course, since the bottom part of the dorsal (the black "photon exhaust" area) is closer to the viewer than the (diagonal) dorsal's upper part one could decide to take the picture with a grain of salt.

OTOH the upper part of the dorsal is rather close to the impulse engines and almost at the same viewing distance, so the width of the upper dorsal could be estimated or calculated by using the width of the impulse engines as a reference.
IMHO it nevertheless gives us a good impression that the TMP Enterprise's dorsal is wider than previously assumed.
