Ishinuki Nagino Yokoana Kofun Gun Tomb #8

This morning as I was reading through my Facebook activity, I came across a post by Ryusei Kimura and liked by my Facebook Friend Toshiji Itoh. He is the NHK TV producer who I met when I was doing the project on Makimuku and the Search for Yamatai Koku, and who helped me secure permission to use the computer graphics I used in that post. Kimura san's post interested me for two reasons. One was the 3D modeling tool he used to create a photo quality model of a late 6th or 7th century tomb. The second reason was the striking similarity to the tombs I has reported on in my post Takaida Yokoana Kofun Gun Takaida Yokoana Kofun Gun. At the time I made that post, I was unable to locate many tombs of similar construction and history, but this tomb, the other tombs in the immediate area, and a similar group on the other side of the hill, look to be very similar and probably were constructed by people in the same wave of Korean immigrants who came to Japan about that time.

The online model is linked to in the placemark. It can be viewed by clicking on one of the 5 numbers, holding down the left click button, and dragging the mouse to rotate around the preselected axis. The mouse wheel can also be used to zoom in or out. I know nothing about the software that created this model, but it certainly looks like it may have many useful applications.

Sketchfab is excellent Washi. Thank you for sharing.

The link did not work for me inside GE but was OK when opened in firefox.

I have built a few 3D models and uploaded some to Sketchfab. You may like to see a local medieval lime kiln I photographed during its excavation by an archaeological society:

The procedure is fairly straightforward but involves taking a lot of photos.

Thanks Brian,



Am I correct in assuming that you have Tools > Options > General > Show web results in an external browser ticked off. By doing that I too was able to make the link to Sketchfab fail.



Kimura san's Facebook post made it seem that a high quality camera might be needed for using Sketchfab. Is that the case? Are the holes in the model areas that were not photographed? Is you model of the fort a model of a model?

Tools > Options > General > Show web results in an external browser now ticked ‘ON’ and the Sketchfab symbol works correctly but the big ‘>’ in the screen centre produces no response for me other than changing to ‘3D’ when I hover the cursor over it.

The lime kiln 3D model is interesting because I was on a guided walk with a small group and while they stood to hear the guide explain the history of the kiln I very quickly scrambled all around the object clicking away with my small ‘pocket’ Nikon while trying hard not to fall into it. I had only about 5 minutes and had never done this sort of thing before so I was very pleased that the result was a reasonable success even though I appear to have missed a few bits. The Nikon is certainly not a high quality camera.The 3d software I use is Agisoft photoscan.

Ideally the subject should be photographed say 50 times over 360° at one elevation and then another 50 times at a second elevation. I only had time for one elevation at the lime kiln. The resulting photos are then processed by Agisoft photoscan during an overnight run.

You can see that the tarpaulin was only partially removed which is unfortunate. My main problem was to prevent others in the group appearing in the camera shots. It would be interesting to return now that the excavation is complete and do the job properly but the land owner does not seem to be keen on the idea.

The fort is indeed a model of a model.
