I looked back at my hobby activities in August 2022.
The activity was extremely concentrated on the 3D technology theme "3D modeling of archaeological survey maps". It has reached a higher level than the initially assumed "Nanchatte" 3D model. It's interesting, so I decided to continue this activity in September.
I looked back on the July 2022 activities of the blog “Walking in the Hanami River Basin” and its family blog.
Focusing mainly on the pottery exhibited at the Yamanashi Prefectural Museum of Archeology Special Exhibition "The Jomon People Drawing Hearts", I was enthusiastic about expressing the results of pattern observation by coloring the 3D model itself.
Regeneration of texture image suitable for UV unwrapping
When UV unwrapping a Jomon pottery 3D model created with photogrammetry, I have found that marking the appropriate seams can significantly reduce the distortion of the regenerated texture image. This will improve the accuracy of texture image editing.
I learned from Google Search that it is possible to perform a batch search for 5 blogs that I operate. I tried it and found that it was very useful for my activity. At the same time, my past hobby activities, which had diminished interest, revived vividly in my brain.

UV unwrapping and texture image regeneration of pottery with binocular protrusions
It is now possible to UV unwrapping a 3D model of pottery with binocular protrusions and regenerate a texture image that matches the unwrapping. This technology also allows 3D models of pottery with binocular protrusions to edit texture images in Photoshop.
I looked back on the activities of the blog "Walking in the Hanami River basin" and its family blog in June 2022.
The main activity in June was to observe the pottery exhibited in the Yamanashi Prefectural Archaeological Museum exhibition "Jomon people who draw the heart" with a 3D model. I became interested in pottery with human face decoration, and it became an activity that I never got tired of.
When I posted a 3D model to Sketchfab that couldn't completely remove noise due to its complicated three-dimensional shape, I received noise removal technical advice from Mr. Thomas Flynn, the cultural property manager of Sketchfab. With that as a trigger, I tried noise reduction measures.
「Thank you for sharing! I wonder if you could try using the 'select points by colour' tool in 3DF Zephyr to remove the white & orange geometry from this scan before creating a mesh: 3dflow.net/technology/documents/3df-zeph...Just an idea :)」
Thomas Flynnさんご指摘の3DF Zephyr チュートリアルを読むと、色指定により指定部分メッシュを削除できます。それを試してみました。スポイトツールでノイズの白を指定すると、ノイズ以外の部分も含めて範囲指定されてしまいます。詳しくは省略しますが、いろいろ条件を替えてもノイズだけを範囲指定することは困難でした。
Warranty replacement for Logicool high-performance mouse
The Logicool High Performance Mouse MX MASTER 3 purchased in September 2020 suddenly became unchargeable. I received a warranty replacement from Logicool one week later. Thank you for Logicool's response.
I learned that even if you accidentally quit the browser (and tabs), you can restore it to its original state with the shortcut key Ctrl + Shift + T. Convenient. I confirmed it with chrome and edge.
