3D Renderings of the 1956-D Mintmark

[georoxx]

For those of you who have this talent, if you bring up Ray's 3D view (the one where 2 side-by-side images appear on your monitor), if you cross your eyes and find what would be the middle of 3 images, you can then focus in on that middle image and actually see it in true 3D. (Kind of like the colorful 3D lithographs that perhaps you have seen.

Very cool.

Well, I've never even figured out how to do overlays yet so I will leave the 3D printing to you. If you want to try something like that, let me know. I could look for a well-punched EDS coin to test the concept on, or you could send me one. Getting the CNC info to the printer might be interesting. The program I used to generate these has a 3D model export function so I'd bet that could be hacked to work with a 3D printer.

One of these days I will run into a 3d printer in some capacity, and when I do, I will try to do this.

Those are pretty cool pics Ray. I am pretty much blind in one eye and can't see out of the other one, but I can see those!

Here's 1951D-1OM-001

Here's a 1949-S Lincoln Cent DDO#3 presented with a couple of techniques.

Unprocessed image using 5x magnification, 25-stack of images:




Unprocessed image using 10x magnification, 36-stack of images:




3D processed 10x image but looking straight on to compare with unprocessed:




3D processed 10x image looking at 45-deg from 9:00:




3D processed 10x image looking at 45-deg from 2:00




I think this technique is useful to help visualize variety details in a similar way to viewing then with a microscope, at least the way I view them. I'm not so sure the 3D versions of these is all that useful, but some may like them. I find them kind of gimmicky, and while they can be sort of cool they don't offer any more information than the 2-D perspective views above. If you disagree, let me know. It's not too hard to include 3D versions of these.

Ray, these are SO much fun to look at. I'm really loving the perspective. As you say, they may not be super useful for identifying varieties, BUT I think some of these shots could be very revealing for looking at some of these odd errors we have recently seen. For example, I think some of us would LOVE to view some of these bizarre rim-restricted design/die deterioration duplications that have recently been posted using this technique.

Will...I do think the 2D "perspective" images may be useful in identifying varieties. I just don't think full 3D images add that much other than novelty factor. If I zoom in, and do a 3D image on a fine detail that really needs stereo imaging to see well, it may be another story...Ray

Here's a 3D image of a 1953D-1OM-001, in XF. I cropped the images to bring the MM closer so it would be easier to see, ie you don't have to cross your eyes as much.

I think those pics are amazing Ray!
