What do we mean by 3D models?
from project-support-wp8.
Or 2.5D?
from project-support-wp8.
2.5-D is a 2-D dataset draped onto a 3-D surface; the data doesn't suddenly become 3-D in such a situation, but it gives the appearance of 3-D, hence 2.5-D
A globe itself may also not be regarded as 3-D if the surface does not have 3 dimensions (x,y,z), it's just another 2-D representation. So a 2-D dataset draped on a 2-D globe is 2-D not even 2.5-D

We might also want to distinguish between sharing (exchanging/downloading) models and accessing models.
So you could for example have some index/catalogue that shows you where models exist and what they do... then give a download ~ so no web view of the model itself, and no direction interaction with it.
and/or you could have some service that interacts with the model, so for example creates a synthetic cross section (for web view or not) or ask some numerical question~ you never get to see the whole model.
and/or you might want some 3D or pseudo-3D view of the model...
For accessing the model we might envisage WCS/WCPS/WPS services
For viewing an index and download WMS/CSW both would work.

So consider the following.
We have a 3-D voxel model on a server and we query it to make a set of 2-D slices along each axis (x-y-z), then we fetch them all and show them in a browser
We are accessing the 3-D model and making a 3D representation that we can interact with ~when all slices are visible it makes a it's a pseudo 3D volume.

Similarly we can have multiple 3D geological surfaces, and query them to make a queryable model in a browser like:
