Loon Lake B-23 Isometric
There's background on the B-23 and how it crashed here:

Here's the story on the image itself. Back in 2009 I attended an aviation archaeology field school. (Long, stupid story....) Anyway, I had my pole aerial photography gear with me and a couple of us thought a good way to survey and document the site would be to take overhead shots of everything. We were hoping to stitch them all together to make a photo-realistic map of the site. The images we got were interesting but, unfortunately, we weren't able to combine all the images into the map we wanted. One software package I had heard of was too expensive for us and another that I did get my hands on was too fussy and wouldn't work with our raw images.
A few days ago, though, I learned about a new web site called Hypr3d.com that lets you upload images and it creates 3D models from them. I didn't mess around. I uploaded all 145 clear images we had of this site and let it chew on that overnight. By morning it had produced a rough model I could view in my browser and a higher resolution one that I could download to my PC. I used another application, Meshlab, to rotate it around to the views I wanted and had it render these two images. Both of these views are rendered in "Ortho" mode so there is no perspective. I think that is why it looks less like a photo and more like a painting or model. So, two years after field school ended, I finally have my orthographic projection of the whole site.
In retrospect, I would do this a little differently if I went back. Because all of our images were shot straight down, more or less, there isn't enough information about the vertical faces of the wreck. This shows up as a lot of distorted shapes on the front and sides. We should have taken more oblique shots from the perimeter looking inward. But when you look at the results from an overhead point of view, it looks damn near perfect.
