Correspondence between pottery fragments in excavation photos and the distribution map of densely packed pottery in 3D space
By observing the correspondence between pottery fragments shown in excavation photos and the distribution map of densely packed pottery (information derived from artifact registers and artifact distribution maps), I was able to truly appreciate the high accuracy of the 3D coordinates of artifacts obtained from paper documents.
Spatial Settings for Statistical Analysis of Artifacts in 3D Space
A spatial setting was created for statistical analysis of the distribution of artifacts by species excavated from the shell layer on the northern slope of the Ariyoshikita Shell Mound in 3D space. Blender's Shrinkwrap modifier was used to set up the 3D space.
Shell layer divisions and artifact distribution in 3D space
The shell layer divisions and artifact distribution in the study space (3D space) of the shell layer on the north slope of the Ariyoshi Kita Shell Mound were observed using a 3D model. The artifacts excavated from the slope shell layer are prominent. The artifacts excavated from the collapsed layer indicate the existence of a shell layer containing artifacts from a previous era that was lost due to gully erosion.
Understanding the relationship between shell layers and artifacts in 3D space 2 (3D spatial arrangement of materials)
A test space framework was set up in Blender to display the shell layers and artifacts in the shell layer on the north slope of the Ariyoshi Kita Shell Mound in 3D space and examine their relationship. 331 grids were used as the test grid, and a shell layer cross section, shell layer major division boundary surface, and artifact distribution map were placed.
Understanding the relationship between shell layers and artifacts in 3D space 1 (organizing materials)
I will try to understand the relationship between shell layers and artifacts in the shell layers on the north slope of the Ariyoshi Kita Shell Mound in 3D space using a test grid. This was made possible by creating a shell layer cross section, creating an artifact ledger database, and having an artifact distribution map. First, I organized and confirmed the materials.
Creating a 1m buffer of pottery fragments in 3D space
A prototype 1m buffer space was created for the distribution of pottery fragments in the 3D space of the shell layer on the northern slope of the Ariyoshi Kita Shell Mound. It seems to be one of the expression materials for visualization of the 3D distribution of pottery fragments.
A rudimentary BlenderPython script to represent object density in 3D space
I wrote a rudimentary BlenderPython script that expresses the distribution density of a mesh object (CUBE) in Blender3D space. Backed by ChatGPT. Creating 3D heatmaps is no longer a dream.
Arrangement of Jomon model in 3D space of Ariyoshi Kita shell mound northern slope shell layer
I placed a Jomon model in the 3D space of the shell layer on the northern slope of the Ariyoshi Kita Shell Mound. As a result, it became possible to grasp the sense of the vastness of the north slope shell layer space, which had been vague until now, as a realistic sense. One burial activity site and two related ritual sites have emerged.
