Description
This function merges multiple 3D models of the same type into one. This function cannot merge 3D models of different types. For example, this function cannot merge scene objects of the gltf type with scene objects of the osg type.
The following figure shows an example.
Four neighboring 3D models exist before the merge.

One 3D model exists after the merge.
