MammothPaleo_Guy's Most Recent Photosynths

Mystery Rib

"After a long hiatus, a new point cloud! This one is of 93HS0031, perhaps the most unusual rib in the sinkhole. Bonus points if you can tell me why."

"This is a synth of a 12"X4"X2" block of foam done to quantify the level of distortion that can be expected in the synthing process. It isn't a very interesting subject, the results should be enlightening."

"This is a semi-experimental synth of our badly scrambled mammoth, Humpty-Dumpty. It uses a relatively small number of photos, taken with multiple zoom levels from a relatively small number of positions. I don't have very high hopes for it, but maybe it'll produce something salvagable."

"The lower jaw of [Mammuthus columbi] showing the enamel plates forming in the back of the jaw, behind the teeth currently in occlusion."

"Hello, All! This synth is of a small tooth from a western camel, [Camelops hesternus]. [Camelops] was one of the last camels native to North America, the continent where the group originated 30+ mya. This synth is based on a very large number of not-too-terrific pictures. I'm hoping it'll work anyway, because using the semi-secret system I've got going really speeds up the synthing process. Wish me luck!"

"Photosynth really seems to be choking on this project!"

"I'm done with top-secret stuff for the moment, and I'm back to more conventional synths. This is another snyth featuring our bisected mammoth, Elvis the Pelvis. I added about 200 pictures to the data set I used before. This means that I'm mixing normal and wide-angle shots -- I rather curious to see how it works! By the way, I'm planning on using this particular synth in conjunction with the 2D mapping efforts here at the site. I show you how later. RESULT: Seems to have worked just fine!"

Top Secret Experimental Mammoth

"This synth is so top-secret that I can't yet tell you much about it. Suffice to say, it is a synth of the west-end mammoth, Murray Antoinette. I know now that a large number of images cannot fully compensate for low resolution, but I'm hoping I can get away with it. I'm not expecting a fantastic point cloud here, but any kind of 3D would be just fine. RESULT: It seems to have worked, for the most part -- there does seem to be pretty significant distortion in the point cloud, though."

Tony,

If I told you the details, it wouldn't be secret! Broadly though, what makes it special is:

1. How the (many) images were obtained and . . .
2. How the resulting synth will be used.

"A quick synth with just a few photos that the assistant curator took of the exposed part of a newly discovered skull. RESULT: Pretty darn good! You don't need many pictures, if the pictures are high-res, no? Kudos, Justin."

"This is a pretty big synth, with about 95% low-res pictures that I enlarged and enhanced in Photoshop, and 5% high-res pictures that didn't need any fussing. My last experiment in this vein didn't go so well (the computer shut down six hours in), but I'm using about 1/4 the previous number of photos (800) so hopefuly it won't choke. Anybody have any tips on making low-res pictures synth? RESULT: Blech. 50%? It didn't seem able to integrate any of the different vantage points. More problematic is that picture taken from the same view, but with (considerably) different resolutions didn't synth well either. Anybody know a way around this? P.S. The individual point clouds for each are actually OK. Wierd that they didn't integrate."
