Cool little 3D photo app

Lovely, got it right away. Must be due to years of practice looking at air photo stereo pairs. I must try this out.

John - When I was in the Army and studying map making at Ft. Belvoir, Virginia, we used stereo pairs of terrain to draft contour maps. Brings back memories.

Gary,

I started looking at stereo pairs in university in the early 70's and continued doing so occasionally during my career in hydro consulting. We would look at stereo pairs with vertical exaggeration and it was quite stunning to see this. I got so that I could hold out 2 adjacent photos in front of me and get my eyes to focus (unfocus) to see the terrain in 3D. Of course, using even the simple pocket type stereoscope helped.

Then came LIDAR and 3D mapping of the ground and top of vegetation, but the air photos were still useful to see what was actually on the ground.

Wow. Didn't know that could be done without a viewer.

Very effective.

Wow. Didn't know that could be done without a viewer.

As long as the images don't get too wide.
