Is there a difference between "3D model monomer" and "monomer modeling"?

Monomer modeling: objects (such as buildings, street lamps, trees, etc.) that need to be managed separately in the process of manual modeling. ) will naturally be made into a separate model, which is a separate entity that can be selected.

Three-dimensional model unit: oblique photography three-dimensional model, laser point cloud and other geographical scenes. After cutting, reconstruction, vector superposition and other operations, geographical entities are built into independent objects in three-dimensional form, which can be independently expressed, linked with attributes and queried for statistical analysis.

BACKGROUND: The 3D model of a real scene can be regarded as a continuous grid covered with high-resolution images. In practical application, it can only be viewed as a base map like an image map, and it is impossible to select geographical entities and query attributes separately. Single building can give corresponding semantic information to meet the different needs of users, which is particularly important in various industries. At present, there are three-dimensional modeling software cc and M3D.
